A chemical engineer who almost chose music as a major and went on to work on a project that was named one of Time Magazine’s Best Inventions of 2023 has been selected as speaker for the First Year Engineering Lecture Series.
Her talk takes place at 6 p.m. Monday, Aug. 26, in Michigan Tech’s Rozsa Center for the Performing Arts.
Christopher Middlebrook (ECE) was a panelist at a meeting on May 9 hosted by the Upper Peninsula Economic Development Alliance (UPEDA). The event took place at Northern Michigan University. Distinguished leaders from universities and community colleges in Michigan’s Upper Peninsula discussed innovations in the higher education landscape of the U.P. Panel discussions will explore challenges and collaborative opportunities with the workforce.
Middlebrook, a professor in the Department of Electrical and Computer Engineering, will discuss the new semiconductor-focused curriculum and learning paths now being developed at Michigan Tech — both for traditional undergraduate engineering students, and for other individuals interested in short-term, flexible training to jump-start career paths for in-demand job roles in the semiconductor industry in Michigan.
A wide range of students will be eligible to participate in the new semiconductor learning programs at Michigan Tech, including high school students, University students, community college students, job seekers and veterans. Learning will occur online, on campus at Michigan Tech and on-site at industry partner locations. Scholarships, transportation, child care and other wraparound services will be available to support students. Much of the new curriculum will kick off in fall 2024, said Middlebrook, with further details to be announced. To receive updates via email, add your information to the Michigan Tech Electronics Hub sign-up form.
Some opportunities for high school students will be happening this summer through Michigan Tech’s Summer Youth Programs (SYP). The week of July 21-26, students in grades 9-11 can attend NEXT Scholars: Semiconductors, a weeklong exploration offered on campus. Full sponsorship of the cost is available for 12 students for the program. “This will allow students to attend at no cost, which is very exciting and such a wonderful opportunity,” noted Middlebrook.
In addition, students who take part in two additional SYP sessions, Women in Engineering (June 16-21) and Engineering Scholars (June 23-28), will have opportunities for hands-on semiconductor fabrication activities and field trips to nearby Calumet Electronics.
MTU has received grants totaling $970,000 from the Michigan Economic Development Corporation to support a major expansion of semiconductor education and training programs for workforce development in Michigan. The amount includes $770,000 for the semiconductor curriculum work and $200,000 for the Michigander Scholars Program.
“Our overall goal is to form a talent pipeline to meet Michigan’s increased demand for skilled engineers and technicians in the semiconductor industry, where jobs are projected to grow at least 11% in the next five years,” said Middlebrook.
At Michigan Tech, Middlebrook teaches courses in electrical and computer engineering, with active research in electrical and optical interconnects and platforms. He serves as the faculty advisor for the IPC-Electronics student chapter at Michigan Tech, and directs the Plexus Innovation Center, a professional-grade, electronics-focused makerspace.
Michigan Tech MS and PhD students will attend a free National Science Foundation (NSF) Innovation-Corps Bootcamp on campus on Thursday Feb. 29 and Friday March 1 to explore tools of design and innovation—and learn how to apply them to their career paths.
The intensive workshop quickly reached its capacity, so facilitators are already planning to add another NSF I-Corps Bootcamp later this year for interested MTU graduate students.
Launched in 2011, the NSF Innovation Corps, or I-Corps, trains scientists and engineers to carry their promising ideas and technologies beyond the university and into the marketplace to benefit society. Michigan Tech has been part of the NSF I-Corps Site program since 2015—introducing the entrepreneurial mindset to over 300 researchers, faculty, staff and students, and helping teams assess the commercial potential of more than 150 technologies.
In an effort to nurture a regional innovation ecosystem and move more discoveries from the research lab to the real world, the NSF established a Great Lakes Innovation Corps Hub in 2021. The 11-university Hub is led by the University of Michigan (U-M), and it’s one of five Hubs across the country. Michigan Tech is a member of the Great Lakes Innovation Corps Hub, along with Purdue University, the University of Illinois Urbana-Champaign, the University of Toledo, the University of Minnesota, Iowa State University, Missouri University of Science and Technology, the University of Akron, the University of Chicago, and the University of Wisconsin-Milwaukee.
The Great Lakes I-Corps Hub aims to connect people at a large scale to increase the “effective density” of the Midwest’s innovation ecosystem. Mary Raber, Michigan Tech I-Corps principal investigator and chair of the Department of Engineering Fundamentals, leads the program at Michigan Tech.

LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world. Available for virtually all building types, LEED provides a framework to design, construct and operate healthy, highly efficient, cost-saving, green buildings.
Are you a student, faculty member or staff at Michigan Tech? If so, you are invited to prepare for, and when ready, take the LEED Green Associate exam. The prep will take place during two sessions, at a low cost, right here at Michigan Tech, with expert training from an original founding member of the US Green Building Council—Michigan Tech alumnus Joe Azzarello.
The LEED exam prep training at MTU will take place over two days. Azzarello will teach on campus in two 5-hour sessions, from 12-5 pm on both Sunday, March 20 and Sunday, March 27. The room is ChemSci 211. Those who cannot attend in person can attend via Zoom. LEED exam training costs $80.00, which includes notes and printed materials. Attendees are expected to purchase their text book, which varies in cost from $73.00 to $115.00, depending on e-book or vendor.
“Attendees will be well trained in what to study for the exam to become accredited as a LEED Green Associate,” notes Azzarello. “Then they must register, take, and pass the LEED GA exam from the USGBC at a later date in order to receive accreditation. The complete costs for LEED Green Associate accreditation varies. The USGBC website provides information on the Steps to Become a LEED Green Associate.
There is no need for a college degree. “Literally anyone can take the course if they can read, memorize some information, and add and subtract,” says Azzarello.
The USGBC LEED Green Associate exam measures general knowledge of green building practices and how to support others working on LEED projects. “The exam is ideal for those new to green building. It’s an accreditation that can enhance your current endeavors, and also open doors to new career opportunities,” Azzarello explains. “LEED accreditation is a globally recognized symbol of sustainability achievement and leadership.”
Depending on interest, Azzarello may offer more LEED training to Michigan Tech students, faculty and staff. Next up would be the LEED Accredited Professional Exam for individuals who actively work on green building and LEED projects.
Azzarello is a LEED AP® and a registered and active USGBC® Faculty™. He is licensed to instruct multiple USGBC workshops and has led workshops throughout the United States, Mexico, South America, China, Thailand, Hong Kong, Singapore and Vietnam. He truly enjoys instructing and sharing his 20-plus years of USGBC and LEED experience while bringing new professionals into the green building movement.
Azzarello earned his BS in Mechanical Engineering from Michigan Tech 1978 and an MS in Environmental Engineering in 1996 from Wayne State University. He is an adjunct instructor in the Department of Chemical Engineering, and also serves as advisor to Michigan Tech’s Alternative Energy Enterprise team.
“I am at the stage of my life now where it is time to give back to Michigan Tech and the community and am in the position to do so,” says Azzarello. “Without a degree from MTU I am not sure how my life would have turned out. I feel very fortunate to be able to give back.”
Prior to joining Michigan Tech, Azarello retired from Kohler Co. as a senior staff engineer focused on sustainability, directing the company’s green building efforts and serving as a global consultant to customers developing green building projects. With decades spent in the environmental field, Azzarello’s resume touts myriad experiences with recycling, energy efficiency, sustainability, co-generation, marketing, sustainable product design and green building design, and construction programs for several Fortune 500 companies, along with multiple smaller organizations as a sustainability consultant. He also served as Yellowstone National Park’s green building consultant.
Azzarello has been a part of the green building movement since its beginning. He served on the USGBC’s first Board of Directors as Vice Chairman, actively involved as a Board member during its formative years. He helped pave the way for LEED by participating in the Beta testing of the newly developed green building guidelines that became known as LEED v1.0. Read Joe Azzarello’s full bio.
Jeremy Bos and Darrell Robinette, mentors and advisors of Michigan Tech’s SAE Autodrive Challenge (and both Michigan Tech alums) share their knowledge on Husky Bites Live, on campus in the Rozsa Center at Alumni Reunion 2021. The session takes place Friday, August 6 at 1:30 pm ET. Everyone in attendance will learn something new, with time after for Q&A.
Can’t make it in person? Join us remotely. We’ll share a link to join the Zoom webinar on the Alumni Reunion website as the event draws near. Afterwards (weather permitting) you’re invited to join us out on the Walker Lawn. Meet the students of Prometheus Borealis and Robotics Systems Enterprise, get a close look at their autonomous vehicles—and be sure to bring your questions.
Starting with a Chevy Bolt, Michigan Tech students outfit it with sensors, control systems and computer processors to successfully navigate an urban driving course in automated driving mode. And, test it in blizzard conditions!
It’s also an ambitious project with an equally ambitious goal: Three years of the competition, with increasing levels of autonomy and more difficult challenges in each successive year.
Michigan Tech’s team is Prometheus Borealis, after Prometheus, the Greek deity responsible for bringing technology to people, and Boreas, the purple-winged god of the north wind.The SAE Autodrive Challenge competition is jointly sponsored by General Motors (GM) and the Society of Automotive Engineers International (SAE).
“The competition focuses on the electrical engineering, computer engineering, robotics engineering, and computer science skills needed to implement the sensors, signal processing and artificial intelligence needed to make the car drive itself,” says team co-advisor, ECE Assistant Professor Jeremy Bos. “Mechanical engineers and a wide range of other disciplines are represented on the teams, as well.”
ME-EM Assistant Professor Darrell Robinette is the team’s other co-advisor. Robinette worked as an engineer at GM for 9 years before joining Michigan Tech in 2014, with roles in transmission, NVH, electrification and calibration engineering groups. He is a longtime First Robotics Competition mentor, too.
Bos earned his BS at Michigan Tech in 2000, and returned to earn his PhD in 2012, both in Electrical Engineering. Robinette earned a BS in 2004 and a PhD in 2007, both in Mechanical Engineering.
On the student side, the AutoDrive Challenge project is spearheaded by Robotic Systems Enterprise (RSE), also advised by Bos and Robinette. RSE is part of Michigan Tech’s award-winning Enterprise program. “It’s one of the best places on campus to learn robotics,” says Bos. The team’s many projects come in many shapes and sizes, from designing a vision system for work with a robotic arm, to an automatic power management system for weather buoys. Clients include Ford Motor Company and Michigan Tech’s Great Lakes Research Center.
The four-year challenge wrapped up on June 14 with Michigan Tech’s Prometheus Borealis team earning 3rd place overall, bringing home the second most trophies. Teams from University of Toronto and University of Waterloo earned first and second overall. Read the full results on the SAE Autodrive Challenge website.
Teams from eight North American universities competed: Michigan Technological University, Michigan State University, Kettering University, University of Waterloo, University of Toronto, Texas A&M University, Virginia Tech, North Carolina A&T State University
“We’re going to need a bigger trophy case.”
Also in June, SAE International and General Motors (GM) announced 10 collegiate teams selected to compete in AutoDrive Challenge II. Michigan Tech was on the list.
The competition continues the strong collaboration between GM and SAE in STEM education and will build on the groundbreaking success of the first iteration of AutoDrive Challenge. Teams will develop and demonstrate an autonomous vehicle (AV) that can navigate urban driving courses as described by SAE J3016™ Standard Level 4 automation.
The following 10 university teams will participate in AutoDrive Challenge II:
Kettering University, Michigan Technological University, North Carolina A&T State University, The Ohio State University, Penn State University, Texas A&M University
University of Toronto, University of Wisconsin – Madison, Queens University and Virginia Tech.
“At General Motors, we envision a future of zero crashes, zero emissions and zero congestion, and we have committed ourselves to leading the way toward this future,” said Dan Nicholson, GM vice president, global electrification, controls, software and electronics and executive sponsor of the competition.
“The AutoDrive Challenge is a great way to give students the hands-on experience they need to find success,” he adds. “We are very excited to work with these talented students over the course of the competition and know they will make an immediate impact on the automotive industry upon graduation.”
“Michigan Tech’s SAE AutoDrive Challenge team has proven our students innovate to succeed.”
When I was 5, my dad took me for a tour at his place of work, Detroit Edison’s Belle River Powerplant. It was awe inspiring seeing all the equipment and getting an explanation of how it worked and what it did. Pretty amazing that they hang the boilers from the ceiling, eh? Everything at the plant was just so cool, especially the controls and control room.
My dad introduced me to all the engineers he worked with, and all of them were MTU grads. They played a part in encouraging me where to go for engineering, even though I was only 5 years old. My dad gave me a Babcock & Wilcox Steam book after the visit. Even though I didn’t understand all the engineering in it at the time, pictures of the power plant equipment, construction, assemblies all caught my interest.
Also, like most engineers, l played with Legos during childhood. Lots and lots of Legos to build whatever my imagination could create.
I go mountain biking whenever I can, also wake surfing, snowboarding, and cross country skiing. My wife, Tara, is an MTU alumna (Pre-Med/Biology ‘07). She is one of the Emergency Room physicians at Portage Health Hospital. We have two daughters: Adelyn, 3, and Amelia, one. I like building, tinkering and fixing (typical mechanical engineer stuff), and trying to be a super dad for my girls.
My Dad ran a turn-key industrial automation and robotics business throughout most of my childhood. In fact, I got my first job at age 12 when I was sequestered at home with strep throat. I felt fine, but couldn’t go to school. My Dad put me to work writing programs for what I know now are Programmable Logic Controllers (PLCs); the ‘brains’ of most industrial automation systems.
I really liked these new things called ‘personal computers’ and spent quite a bit of time programming them. By the time I was in high school I was teaching classes at the local library on computer building, repair, and this other new thing called ‘The Internet’. I ended up in engineering because I like to build things (even if only on a computer) and I like to solve problems (generally with computers and math).
I live in Houghton with my wife and fellow alumna, Jessica (STC ’00). We have a boisterous dog, Rigel, named after a star in the constellation Orion, who bikes or skis with me on the Tech trails nearly every day. When I have time I also like to kayak, and stargaze.
Launched by Dean Janet Callahan in 2020 near the start of the pandemic, Husky Bites is an interactive Zoom webinar that takes place each fall and spring.
During the semester, every Monday at 6, rach “bite” is a suppertime mini-lecture, presented by a different Michigan Tech faculty member, who weaves in a bit of their own personal journey, and brings a co-host, as well—an alum or a current student who knows a thing or two about the topic at hand.
The Husky Bites weekly Zoom webinar series resumes starting Monday, Sept. 13.
“We’ve had attendees from nine countries, and a great mix of students, alumni, our Michigan Tech community and friends,” says Dean Callahan, who mails out prizes for (near) perfect attendance.

Pengfei Xue and Guy Meadows generously shared their knowledge on Husky Bites, a free, interactive Zoom webinar hosted by Dean Janet Callahan. Here’s the link to watch a recording of his session on YouTube. Get the full scoop, including a listing of all the (60+) sessions at mtu.edu/huskybites.
What are you doing for supper this Monday night 11/30 at 6 ET? Grab a bite with Dean Janet Callahan and Civil and Environmental Associate Professor Pengfei Xue, Director of the Numerical Geophysical Fluid Dynamics Lab at Michigan Tech’s Great Lakes Research Center.
Catch a glimpse of the future during his session, “Severe to Extreme: Modeling Climate Change and Coastal Hazards on the Great Lakes.”
The Great Lakes are more like inland seas. From the cold depths of Lake Superior fisheries to the shallow algae blooms of Lake Erie, the bodies of water differ greatly from one another. Yet they are all part of one climate system. Together they contain one-fifth of the world’s surface freshwater.
Xue uses mathematical modeling to analyze and predict the short-term and long-term responses of that system to climate stressors. During Husky Bites, he’ll introduce the regional earth-system model he uses to understand and predict how the Great Lakes system responds to weather extremes and coastal hazards.
Joining in as co-host for Husky Bites is Guy Meadows, who collaborates with Prof. Xue on the work.
We’ll get to see three modeled visualizations of the same storm passing by on Lake Superior. In each scenario, they’ll show and explain what could happen along the coast.
“The Great Lakes exert a strong influence on the physical, ecological, economic, and cultural environment in the region, across the nation, and internationally,” says Xue. “Human activities expose the system to multiple stressors. Climate change creates new risks and exacerbates existing vulnerabilities,” he adds.
“This is a simulation of a numerical tracer released from the Cuyahoga River near Cleveland, Ohio. It shows how a river plume goes into Lake Erie and mixes with the lake water,” says Dr. Pengfei Xue.
“In my lab, we analyze and predict short-term events. We also project the long-term influence of climate change on the Great Lakes ecosystem. Our goal is to help inform decision-making and management. One of the important concepts in climate change, in addition to knowing the warming trend, is understanding that extreme events become more severe,” Xue says. “That is both a challenge and an important focus in regional climate modeling.”
It takes a supercomputer to run the calculations. Xue uses Superior, the supercomputer housed in the Great Lakes Research Center, to build high-fidelity models and detailed simulations for a region where more than 30 million people rely on the Great Lakes for water and other resources.
“I do the science part, but I also want to apply my findings.”
With his next generation numerical predictive models for the Great Lakes, Xue seeks answers to many “what-if” questions. “How will projected future climate change impact water levels, wave energy, sediment transport and shoreline damage?”
He also looks at short-term, episodic events like algal blooms and weather patterns.
His current research focuses on an Integrated Regional Earth System Model (IRESM, for short) for the Great Lakes region. The model consists of coupled atmosphere, lake, ice, wave, sediment, land surface, and biological components, and includes data assimilation and machine learning techniques.
The bottom line: Xue seeks to better understand the processes in the Great Lakes and their impact on people.
“We are extremely fortunate to have Professor Xue at Michigan Tech and the Great Lakes Research Center,” says Professor Guy Meadows. “He has built very strong bridges both within the University and with our government research partners. Thanks to these partnerships, we have modeling of the Great Lakes running on Superior at a resolution not previously thought possible.
Meadows joined Michigan Tech in June of 2012, to help establish the new GLRC. “This is a unique, amazing place. The future of Great Lakes research is based right here.”
Prof. Xue’s modeling research experiences in other regions include Massachusetts Coastal Waters, Gulf of Maine, East China Sea, the Maritime Continent in Southeast Asia, and the Persian Gulf.
Prof. Xue recently joined Argonne National Lab as a joint appointee Scientist in the Environmental Science Division. His joint appointment will expand the already deep capabilities of both institutions. Michigan Tech’s GLRC Director Andrew Barnard agrees. “Dr. Xue’s collaborative work with Argonne will result in cutting-edge science and engineering solutions in predictive hydrodynamics.”
I liked math when I was a little kid. I was very much influenced by my father. He was a high-school physics teacher and would often pose math- or physics-related questions to challenge me for fun. Later when I was in college, I majored in mathematics and became very interested in how to apply math to helping answer some real-life questions. That’s how I got interested in numerical modeling and ended up what I am working on now.
After finishing my doctoral study at UMASS-Dartmouth and post-doctoral work at MIT, I moved to Tech seven years ago. I live with my wife and two cute kids in Houghton. We enjoy spending time reading and playing together. You may see me up at Michigan Tech’s Student Development Complex working out or swimming, or out on the trails skiing—to relax and take my mind off work.

Where Modeling Meets Observations: Improving the Great Lakes Operational Forecast System
Orhan Soykan and Tim Kolesar generously shared their knowledge on Husky Bites, a free, interactive Zoom webinar hosted by Dean Janet Callahan. Here’s the link to watch a recording of his session on YouTube. Get the full scoop, including a listing of all the (60+) sessions at mtu.edu/huskybites.
Dean Janet Callahan had supper with Orhan Soykan, a prolific inventor and professor of practice in biomedical engineering at Michigan Tech with more than 100 patents to his name. Joining in will be one of Dr. Soykan’s former students, Tim Kolesar, MD, who earned his biomedical engineering degree at Michigan Tech in 2019 after first completing med school. He’s now a Development Quality Engineer at Abbott.
Soykan specializes in implantable devices, biosensors, and molecular medicine. He is the co-founder of two start-ups and has been a consultant to more than 20 firms.
He has long been associated with Michigan Tech, first as a master’s student in electrical engineering (he graduated in 1986), then as an adjunct faculty member in the Department of Electrical Engineering. Then, seven years ago, after working 20 years at biomedical device powerhouse Medtronic and several more at startup YouGene, Soykan rejoined the University in a more formal way, as a professor of practice in Michigan Tech’s Department of Biomedical Engineering.
He teaches a biomedical instrumentation lab and courses on medical devices, medical imaging, and numerical physics. He also mentors senior design teams of undergraduate students who work on projects for industry clients, the final big design project of their senior year.
Michigan Tech BME alum, Tim Kolesar ‘19 was one of his students. “Dr. Soykan was my senior design team advisor,” says Kolesar. “Our team (three biomedical engineers and one electrical engineer) all worked together on a project for Stryker, investigating the thermal side effects of a surgical device used in brain surgery.”
Before coming to Michigan Tech, Kolesar earned a BS in Human Biology from Michigan State University, and then a Doctorate of Medicine from the American University of Antigua College of Medicine, in the Carribean. He also volunteered as a medical practitioner for the Himalyan Health Exchange, providing health care for underserved populations within remote regions along the Indo-Tibetan borderlands.
After graduating from Michigan Tech, Kolesar landed his dream job at Abbott, a multinational medical devices and health care company with headquarters in Abbott Park, Illinois, He works on cardiovascular devices for Abbott, including aortic and mitral heart valve replacements. At the moment he’s lead engineer on two projects, involved in device submission to the FDA in the US, and the EMA (European Medicines Agency) in the European Union.
Kolesar underscores the importance of time spent in the lab. During his time at Tech, he worked as an undergraduate researcher in the labs of biomedical engineering professors Dr. Rupak Rajachar and Dr. Jeremy Goldman, working on tissue engineering for injury repair in joints, and bioabsorbable stents for the heart. “These two opportunities played a large role in confirming my decision to pursue a career in biomedical engineering,” he says. “I believe the lab experience I gained at Michigan Tech played a pivotal role in securing my current role at Abbott.”
“I believe necessity is the mother of all invention. You must truly understand the problem and the boundaries the solution will have,” says Soykan. “After that, it is absolutely necessary to study scientific and engineering principles relevant to the problemAmong all his inventions, Dr. Soykan says he is most proud of those at the intersection of engineering and biology. His favorite: A method of isolating a small portion of a patient’s own heart muscle and converting it into a sensor to monitor levels of an antiarrhythmic heart medication.they will eventually become the tools for the development of the solution. And finally, you must look at work done by others, by reviewing technical literature and patent publications,” he adds.
“Now you are ready to tackle the problem by thinking as creatively as you can. This can be anywhere—outside when running or skiing, driving in traffic—make a list of the solutions you think of and discuss them with your colleagues and experts in the field. Finally, the ones that seem to pass the test, try them in the lab.”
I grew up in Ankara, the capital city of Turkey. I became interested in science and technology through my high school physics teacher. Eventually I began to build some electronic circuits as a hobbyist, which eventually turned into a profession. I cannot forget about the contributions of Mr. Spock from the original Star Trek series. (And yes, I am old enough to remember watching the original episodes each week on TV as a young boy!
Among all my inventions, I am most proud of a method of isolating a small portion of a patient’s own heart muscle and converting it into a sensor to monitor levels of an antiarrhythmic heart medication.
I earned my BS from Middle East Technical University, my MS from Michigan Tech and my PhD from Case Western Reserve University, all in electrical engineering. I worked for NASA in Huntsville, Alabama, the Food and Drug Administration in Rockville, Maryland, and Medtronic in Minneapolis and Tokyo, before becoming a part-time consultant to the medical device industry and a part time faculty member at Michigan Tech. I actually maintain two residences, one in Houghton, and the other in the Twin Cities. I’ve got labs in both homes. I commute weekly between the two locations with my single engine Mooney. When I am not working or flying, I’m usually busy training for my annual marathon, or cross country skiing at Tech trails.
Whether I knew it or not, engineering has always been a part of me. My love for Physiology pushed me towards the world of medicine. However, during my third year of medical school, I had the pleasure of working with an orthopedic surgeon, and mechanical engineer, in Atlanta, Georgia. The experience truly opened my eyes to the realm of biomedical engineering, and sparked a fascination with the possibilities. This eventually led me back to Michigan Tech upon completion of my medical degree.
My wife, Jenn and I were both raised in the Upper Peninsula of Michigan. We now reside in the Minneapolis area. During my time at Michigan Tech we loved being able to return to the Upper Peninsula. The Keweenaw quickly became our second home, especially Copper Harbor. We spend our free time biking, nordic and downhill skiing, camping, hiking, running, and exploring the outdoors with our two dogs Kewee (short for Keweenaw) and Birch Bark.
Sarah Sun and George Ochieze generously shared their knowledge on Husky Bites, a free, interactive Zoom webinar hosted by Dean Janet Callahan. Here’s the link to watch a recording of her session on YouTube. Get the full scoop, including a listing of all the (60+) sessions at mtu.edu/huskybites.
What if your medical heart monitor was embroidered right on your shirt, in your favorite design? And what if it was powered by your own movements (no battery required)? And what if you could even design and order it yourself, right on the internet? Get ready to learn all about this, and more.
Join Dean Janet Callahan for supper along with Sarah Sun, an associate professor of mechanical engineering, and George Ochieze, a graduate student researcher in Dr. Sun’s Human-Centered Monitoring Lab at Michigan Tech.
Sun is the lead investigator of three National Science Foundation research grants totaling $1 million focused on wearable electronics. She is also the director of the Center for Cyber-Physical Systems within Michigan Tech’s Institute of Computing and Cybersytems ICC.
“I am passionate about using engineering solutions to solve health problems,” she says. “We’re trying to solve long-existing technical challenges to improve medical devices, and we’re developing new technologies, too, in order to enable more diagnosis solutions.”
One of Sun’s large research projects involves developing new human interfaces for monitoring medical vital signs.
Their goal: to provide a reliable, personalized monitoring system that won’t disturb a patient’s life, whether at home, while driving, or at work. “Right now for patients there’s a real trade-off between comfort and signal accuracy. This tradeoff can interfere with patient care and outcomes, too,” she explains.
Sun hopes to use electrophysiological sensing and motion sensing to help prevent automobile crashes, especially those that occur when drivers accidentally fall asleep at the wheel. According to the National Highway Traffic Safety Administration, while the precise number can be hard to nail down, drowsy driving is a factor in more than 100,000 crashes in the U.S each year, resulting in nearly 1,000 deaths and 50,000 injuries.
First, though, Sun and her team needed to figure out how to overcome a major challenge in monitoring vital signs: motion artifacts, or glitches caused by the slightest patient movement, even shivering, or tremors.
“ECG, a physiological signal, is the gold standard for diagnosis and treatment of heart disease, but it is a weak signal,” Sun explains. “Especially when monitoring a weak signal, motion artifacts arise.”
Sun and her team first set out to discover the mechanism underlying the phenomenon of motion artifacts. Then, they realized they were able to tap into it.
“We not only reduce the influence of motion artifacts but also use it as a power resource,” she says. The result: a sensing device that harvests energy from patient movements.
Sun cites recent progress in the development and manufacturing of smart fabrics, textiles, and garments. “This has opened the door for next-generation wearable electronics—fully flexible systems that can be embroidered directly onto cloth,” she says.
“Feel free to download our .exp files for your own wearable system on cloth manufacturing. The code can be processed by regular sewing machines. Just go online to WEF, our new Wearable Electronics Factory.
By using conductive thread and passive electronics—tiny semiconductors, resistors and capacitors—Sun is able to turn logos into wearable electronics. The stitches themselves become the electronic circuit. Sun and her team can embroider on just about anything flexible, including cloth, foam, and other materials.
Sun is also building a manufacturing network and cloud-based website where stitch generation orders can be made. “In the future, a person can upload their embroidery design to generate stitches, or download certain stitches as needed,” she says. The lab provides coding for the electronics and stitch generation to embroiderers. “Soon any embroidery company will have the potential to manufacture embroidered health monitors,” she says.
These wearable, embroidered ”E-logos” can monitor multiple vital signals. They’re customizable, too.
Sun hopes flexible, wearable electronics will interest a new generation of engineers by appealing to their artistic sides. “This type of embroidery circuit really brings together together craft and functional design.”
George Ochieze is pursuing a master’s degree in Mechatronics and a PhD in Mechanical Engineering. He took Sun’s Introduction to Mechatronics and Robotics course at Michigan Tech last spring. That’s when he discovered his own passion: working with machines and control devices. He joined her research group last summer.
“Mechatronics uses electromechanical systems automated for the design of products and processes,” Ochieze explains. “I picked up my research interest after modeling an RRR manipulator using CAD software. That’s a robot manipulator set up with 3 revolute joints. I had some challenges in controlling the joints, and Dr. Sun gave me some tips. She was very helpful in guiding me through the process, and our mentor/mentee relationship in soft robotics was formed,” says Ochieze.
Soft Robotics involves the design and construction of robots from flexible, compliant materials, drawing from the movements and adaptations of living organisms. Soft robots offer new capabilities, as well as improved safety when working around humans, with potential use in medicine and manufacturing.
Ochieze plans to share a demo on soft robotics during Husky Bites.
“Throughout my growth in the engineering field, I have been surrounded by people who are generous enough to share their knowledge. I look forward to mentoring others like me within this field.”
My dad liked to play with old electronics when I was young. I built my first radio receiver in middle school with him although I did not know how those electronics work at that time. This experience really inspired my interest in pursuing an engineering degree. I earned my bachelor’s degree at Tianjin University. It’s located near Beijing, in Tianjin, China, on the Bohai Sea. About six year ago, I earned my PhD in electrical engineering at Case Western Reserve University in Cleveland, Ohio. My doctoral research was on wearable electronics.
I grew up in Northern China, in a town with a very cold winter climate, but dry. My husband came to Michigan Tech first. He liked the U.P. a lot and told me lots of great things about Tech. It was challenging for me to balance work and life at first, especially with two little kids. My son, Brent, is almost 8 now, and my daughter, Leah, is two. My husband and I both like to design and build stuff, so we enjoy it with our kids, too.
I grew up in Aba, in Abia, Nigeria. Working in my Dad’s fabrication company fostered my interest in the engineering field. At a young age I became familiar with machine operations. I was fascinated with the sequence operation of machines to achieve a desired goal. I started developing cars and movable structures with available materials, leading my fellow students in the design of mechanical components.
I am one of two instructors in Michigan Tech’s Career and Technical Education (CTE) Mechatronics program for local high school juniors and seniors. Even in difficult times during the pandemic, these young scholars show overwhelming potential to conquer the mechatronics field—a glimpse into a welcoming future in engineering. They will go on to find degree pathways at Michigan Tech, and excellent careers in smart manufacturing.

Bill Sproule shares his knowledge on Husky Bites, a free, interactive webinar on Monday, September 21 at 6 pm EST. Learn something new in just 20 minutes, with time after for Q&A! Get the full scoop and register at mtu.edu/huskybites.
What are you doing for supper this Monday night at 6? How about grabbing a bite with Bill Sproule, hockey historian and Michigan Tech civil and environmental engineering professor emeritus, along with Michigan Tech alumnus John Scott, NHL All-Star MVP?
Sproule’s research into hockey history began about 15 years ago when he first volunteered to teach a class on the subject at Michigan Tech. During Husky Bites he plans to share the history of the Stanley Cup and tell how a Canadian-born dentist, Doc Gibson, and his “partner in crime” Houghton entrepreneur James Dee made Houghton the birthplace of professional hockey, several years before the National Hockey League came into existence. He’ll also discuss the role Gibson and Dee played in Michigan Tech hockey.
Serving as co-host along with Dean Janet Callahan during this session of Husky Bites is John Scott, an inspiration to many and the embodiment of Husky tenacity.
Sproule and Scott two have a lot in common. A love of hockey, for one. A fondness for Houghton, for another. Both born in Canada. They’re both retired—but not really retired. They’re both authors. Finally, they’re both Michigan Tech engineering alums. Sproule earned his BS in Civil Engineering in 1970. Scott, a practicing engineer, graduated with his BS in Mechanical Engineering 2010.
In college, Scott had no professional hockey ambitions. That was until he met former Huskies Hockey Assistant Coach Ian Kallay. “He said, ‘You can do this. You can make a career out of this. If you put in the work, put in the hours.’ It was a huge moment for me,” Scott recalled.
How does his ME degree impact his game? “It definitely helps me pass a puck. I’m better than most at figuring out a bank pass off the boards. And most guys sharpen their skates to one-half of an inch. But I know how to increase—or not increase—my bore,” he said.
Scott’s wife, alumna Danielle Scott, who earned a BS in biomedical engineering from Michigan Tech in 2006, stepped away from her role with leading biomed company Boston Scientific to care for the couple’s six daughters, one just a few months old. Their oldest is now 8. John works with a mechanical engineering consulting firm in Traverse City. His podcast, Dropping The Gloves, also keeps him busy. “That’s where we talk about hockey, family, and all other things that are going on in my life post-NHL.”
Scott’s number one job, he firmly insists: family. That means raising his six daughters together with Danielle. He says he’s already hoping for number seven.
Actually, engineering was not my first choice. I hoped to become an architect but wasn’t accepted into an architectural program. My uncle was a civil engineer, so that’s why I picked civi; I was thinking structural engineering would be similar to architecture, and I was right, in a way!
I spent my first two years learning at Lake Superior State, a branch of Michigan Tech at the time, then came to Houghton for my junior and senior years, where I took a few transportation courses. After graduating from Tech I headed to the University of Toronto for a master’s degree, specializing in transportation engineering.
After earning my graduate degree I worked for Transport Canada and then joined a transportation engineering consulting firm. I always wondered about teaching, and was hired by a community college to help teach their their transportation engineering program. Teaching soon became my passion. Then, I headed to Michigan State University where I earned my Ph.D. in civil engineering, specializing in airport planning and design. I also taught at the University of Alberta and did more consulting before deciding to join the birthplace of Hockey—and, the faculty at Michigan Tech—in 1995.
At Tech, in my role as professor, I conducted research and taught courses in transportation engineering, public transit, airport design, and hockey history. The hockey history course was always full. How in the world did I end up teaching hockey history? I’ll tell the full story during Husky Bites…
I was born and raised in Sault Ste. Marie, Ontario. My wife, Hilary was born and raised on a dairy farm north of Toronto, and earned her degrees from the University of Toronto and University of Alberta. We met in Toronto on a blind date. Together we raised two sons in Houghton. One graduated in engineering at Michigan Tech and Virginia Tech and now works in the Detroit area. The other is currently a graduate student in art history at Queen’s University in Kingston, Ontario, Canada. All the while Hilary taught in the Physical Therapy Assistance program at nearby Finlandia University.
We’re now retired, living here in Houghton. I’m still active on several professional committees and serve on the executive committee of the Society for International Hockey Research. I’ve taken a few online courses in my retirement, too: Hockey GM and Scouting, and Hockey Analytics.
I’ve penned two books, Copper Country Streetcars, and Houghton: The Birthplace of Professional Hockey. I’m currently working on my third book project, all about the history of Michigan Tech hockey—and doing some cartooning.
