Michigan Tech’s Heat Sink team. Undergraduate students are Gracie Brownlow and Kelsey Brinks. Graduate students are Behzad Ahmadi, Masoud Ahmadi, and Behnam Ahmadi.

A student team from Michigan Tech has been awarded first place in the ASME/K16 and IEEE/EPS Student Design Challenge: Expanding the Possibilities of Heat Sink Design Using Additive Manufacturing.

The competition called upon student teams K-16 to expand the possibilities of heat sink design using additive manufacturing. The four finalist teams are Michigan Tech, Purdue University, University of Arkansas, and Berlin Institute of Technology.

Advanced heat sink designs offering augmented cooling capabilities are required for effective thermal management of high-power electronic chips. Future heat sink designs should not only offer an effective heat transfer but also be compact and cost-effective. 

Composed of Michigan Tech graduate and undergraduate students in the Department of Mechanical Engineering-Engineering Mechanics, the team was first selected as a semi-finalist in March. Now, as a finalist, one member of the team will defend their heat sink design in front of industry leaders in the form of an oral presentation, Behzad Ahmadi. That will take place during the IEEE ITherm 2022 Conference coming up in San Diego from May 31 – June 3, 2022.

Michigan Tech’s Energy-X team heat sink designs: expanding the possibilities of heat sink design using additive manufacturing.

Undergraduate students are Gracie Brownlow and Kelsey Brinks. Graduate students are Behzad Ahmadi, Masoud Ahmadi, and Behnam Ahmadi. Assistant Professor Sajjad Bigham is the team advisor. He is the director of the Energy-X Lab (Energy eXploration Laboratory) at Michigan Tech.

For the competition, all teams were asked to design, build, and validate an aluminum heat sink made with additive manufacturing techniques made available by GE Additive. Next, teams prepared a white paper that justified their designs.

The Michigan Tech team was among selected to print their heat sink with GE Additive machines. It was then sent for testing, which then helped determine the finalists, due to their top designs.

Sustainable Foam: Coming Soon to a Cushion Near You

Published
By
Chemical engineering major Lauren Spahn presented her research at the Michigan Tech Undergraduate Research Symposium. Her lignin project was supported by Portage Health Foundation, the DeVlieg Foundation, and Michigan Tech’s Pavlis Honors College.

Most polyurethane foam, found in cushions, couches, mattress, insulation, shoes, and more, is made from petroleum. What if it could be environmentally-friendly, sustainable, and made from renewable biomass? It’s entirely possible, thanks to the work of chemical engineering student Lauren Spahn and her fellow researchers at Michigan Tech. It all happens in the Biofuels & Bio-based Products Lab at Michigan Tech, where researchers put plants—and their lignin—to good use. The lab is directed by Dr. Rebecca Ong, an associate professor of chemical engineering.

Q&A with Lauren Spahn

Please tell us a little about your work in the lab.

Our goal in working with Dr. Ong is to develop sustainable industries using renewable lignocellulosic biomass⁠—the material derived from plant cell walls. There are five of us working on Dr. Ong’s team. We develop novel co-products from the side streams of biofuel production, and pulp and paper production. We’re trying to make good use of the leftover materials.

 

Lignocellulose, aka biomass, is the dry matter of plants. Energy crops like this Elephant Grass, are grown as a raw material for the production of biofuels.

What kind of research are you doing?

My particular research project involves plant-based polyurethane foams. Unlike conventional poly foams, bio-based foams are generated from lignin, a renewable material. Lignin is like a glue that holds wood fibers together. It has the potential to replace petroleum-derived polymers in many applications. In the lab, we purify the lignin from something called “black liquor”⁠. It’s not what sounds like. Black liquor is a by-product from the kraft process when pulpwood is made into paper. Lignin is collected by forcing dissolved lignin to precipitate or fall out of the solution (this is the opposite of the process of dissolving, which brings a solid into solution). By adjusting the functional properties of lignin during the precipitation process, we hope to be able to tailor the characteristics of resulting foams. It’s called functionalization.

Typically in the lab process, functionalization occurs on lignin that has already been purified. What we hope to do is integrate functionalization into the purification process, to reduce energy and raw material inputs, and improve the economics and sustainability of the process, too.

Purified lignin, used to make bio-foam. The resulting foam will likely be light or dark brown in color because of the color of the lignin. It would probably be used in applications where color does not matter (such as the interior of cushions/equipment).

How did you get started in undergraduate research?

I came to Michigan Tech knowing I wanted to get involved in research. As a first-year student, I was accepted into the Undergraduate Research Internship Program (URSIP), through the Pavlis Honors College here at Tech. Through this program I received funding, mentorship, and guidance as I looked to identify a research mentor. 

How did you find Dr. Ong, or how did she find you?

I wanted to work with Dr. Ong because I found the work in her lab to be very interesting and relevant to the world we live in, in terms of sustainability. She was more than willing to welcome me into the lab and assist me in my research when I needed it. I am very thankful for all her help and guidance. 

Lignin is like a glue that holds wood fibers together, giving trees their shape and stability, and making them resistant to wind and pests. Pictured above, a biofuel plantation in Oregon.

What is the most challenging and difficult part of the work and the experience?

Not everything always goes according to plan. Achieving the desired result often takes many iterations, adjustments, and even restructuring the experiment itself. After a while, it can even become discouraging.

What do you do when you get discouraged? How do you persevere?

I start thinking about my goals. I enjoy my research—it’s fun! Once I remind myself why I like it, I am able to get back to work. 


Lignin at the nanoscale, imaged with transmission electron microscopy (TEM). Raisa Carmen Andeme Ela, a PhD candidate working in Dr. Ong’s lab, generated this image to examine the fundamental mechanisms driving lignin precipitation.

What do you enjoy most about research?

I enjoy being able to run experiments in the lab that directly lead to new designs, processes, or products in the world around me. It’s wonderful to have the opportunity to think up new product ideas, then go through the steps needed to implement them in the real world. 

What are your career goals and plans?

I plan to work in R&D for industry. I am very passionate about research—I want to continue participating in research in my professional career.

Why did you choose engineering as your major?

The field is so large. Chemical engineers can work in industry in numerous areas. I liked the wide variety of work that I could enter into as a career.

OHM and Michigan Tech Alumni team up to Lead Family Engineering Nights in Detroit Schools

Published
By
Fifteen OHM staff helped present the Family Engineering Night sessions, including several Michigan Tech alumni.

From May 10-12, Michigan Technological University teamed up with OHM Advisors to provide STEM outreach at five schools in Detroit. 

The program they presented, Family Engineering, engages K-8 students and their families in engineering investigations. Family Engineering was created by Michigan Tech and partners in 2011 with a grant from the National Science Foundation. A key outcome of the program was the publication of the Family Engineering Activity & Event Planning Guide, published in 2011.

Sessions took place at the schools, followed by free pizza at Mackenzie Middle School, Clippert Multicultural Magnet Honors Academy, and Adams Middle School. The event began with short opener activities that adults and children explore together. These included: Glue is the Clue, Domino Diving Board, Who Engineered It?, Let’s Communicate, Boxing Beans, Picture This, Solid Ground, Hoop Glider, Inspired by Nature, Shifting Shapes, All The Right Tools, and Thrillseekers.

Next, families took part in three Engineering Challenges:

  1. Stop & Think – Why was this object designed? What need did it address? Can you make it better?
  1. Team Up – Discover why engineers work in teams. What helps a team work well together? How can we address challenges?
  1. Give Me Hand – How can an engineer help a person who has lost their hand, or some other part of their body?
Family Engineering Night took place recently in Detroit, with volunteer help from OHM Advisors.

Fifteen OHM staff helped present the sessions, including several Michigan Tech alumni.

Ron Cavallaro, Vice President of OHM Michigan, echoed the value of introducing kids to engineering at an early age. He earned his bachelor’s degree in civil engineering at Michigan Tech and is now a member of the Michigan Tech Department of Civil, Environmental and Geospatial Engineering’s Professional Advisory Board. “Many of the families that attended the events brought younger siblings,” said Cavallaro. It was awesome to see the middle school students, their parents and siblings helping each other on the challenges.”

“OHM Advisors has been seeking out ways to get younger children interested in STEM fields. We are fortunate to have had MTU reach out to us to help with this program.”

Ron Cavallaro, Vice President of OHM Michigan

Chandler Park Academy High School and UPrep Science & Math High School hosted another Michigan Tech alum, retired Lt. Colonel Otha Thornton, chair of Michigan Tech’s Diversity, Equity, Inclusion and Sense of Belonging (DEIS) Alumni Advisory Board, formed in Fall 2021. 

Lt. Colonel Otha Thornton

Thornton presented at four student assemblies as part of the outreach effort. He shared how students could find their own pathway to STEM and described STEM careers. Thornton also described highlights of his own career⁠—working directly with President Barack Obama, First Lady Michelle Obama, and Vice President Biden in the White House, along with Congress, to promote passage of the Every Student Succeeds Act. The Act supports STEM education in K-12 schools. 

Thornton’s STEM work is preceded by a 21-year career with the U.S. military. He earned the Bronze Star Medal for exceptional performance in combat operations during Operation Iraqi Freedom. His other military assignments included working with the White House Communications Agency and U.S. forces in Iraq. As the 53rd president of the National Parent Teacher Association (PTA), Thornton was the first and only African American male to serve as President in the National PTA’s 125-year history. 

Any school can access the Family Engineering Activity & Event Planning Guide to provide positive engineering experiences for K-8 students and their families. For more info, contact: Joan Chadde, jchadde@mtu.edu or 906-487-3341.

Michigan Tech Partners with Lockwood STEM Center: Expanding Educational Access in the Great Lakes Bay Region

Published
By
The Lockwood STEM Center in Hemlock, Michigan opened in 2020, a fantastic place for students to learn and practice robotics.

This month, Michigan Tech launched a partnership with the Lockwood STEM Center, part of Hemlock Public Schools in Hemlock, to provide educational outreach and opportunities to its students.

As part of the partnership, Michigan Tech established a scholarship program for Hemlock students who participate in robotics activities while in high school and then enroll at Michigan Tech as first-year students. The award provides $1,000 and is renewable annually. Two students will begin receiving the scholarship in Fall 2022 (still to be announced).

Students work on a robot in the Blue Marble Security Enterprise. It’s one of 25 different student-led Enterprise teams operating at Michigan Tech

At Michigan Tech a variety of options exist for students who want to pursue robotics. The University also has a new BS in Robotics, in the Department of Electrical and Computer Engineering. Several Enterprise teams are focused on Robotics, including the Robotics Systems Enterprise, advised by Michigan Tech Professor (and alumnus) Jeremy Bos.

“Our partnership with the Lockwood STEM Center is in recognition of the incredible academic opportunities it provides to Hemlock Public School District students. We are thrilled to show our support for the Hemlock community and Great Lakes Bay region,” said Cassy Tefft de Muñoz, Executive Director of Enrollment Initiatives at Michigan Tech.  

“Who has robots? We have robots,” says Michigan Tech’s Robotic Systems Enterprise team, open to all majors on campus.

The Lockwood STEM Center was the vision of Tom and Dana Lockwood, teachers at Hemlock High School (HHS) who sought to advance STEM educational opportunities in the community. The state-of-the-art facility is truly a community effort with support from local individuals, industry and Hemlock Public Schools.

Former HHS student Gary Gariglio earned two bachelor degrees at Michigan Tech—one in electrical engineering (’86), and the other in business (’87). He is now president of Interpower Induction in Almont, Michigan. He delivered a keynote address to students and attendees during a special event on May 4 celebrating the new partnership. Gariglio highlighted the value of his Michigan Tech education and emphasized the importance of perseverance in the face of adversity—giving special acknowledgement to Matt Pumford and Greg Turner of Pumford Construction for their commitment and support in the oversight and construction of the Lockwood STEM Center. Pumford earned his bachelors degree in civil engineering at Michigan Tech in 1988.

The collaboration with Hemlock Public Schools is a continuation of Michigan Tech’s strong presence in the Great Lakes Bay Region. This includes a longstanding partnership with Hemlock Semiconductor supporting educational outreach and student attendance at Michigan Tech’s Summer Youth Programs (SYP).

Michigan Technological University is a public research university founded in 1885 in Houghton, Michigan, and is home to more than 7,000 students from 55 countries around the world. Consistently ranked among the best universities in the country for return on investment, the University offers more than 125 undergraduate and graduate degree programs in science and technology, engineering, computing, forestry, business and economics, health professions, humanities, mathematics, social sciences, and the arts.

Dean’s Teaching Showcase: David Labyak

Published

David Labyak
David Labyak

Dean Janet Callahan has selected David M. Labyak, assistant professor in the Department of Manufacturing and Mechanical Engineering Technology (MMET), for this spring’s Deans’ Teaching Showcase.

Labyak will be recognized at an end-of-term luncheon with other spring showcase members, and is a candidate for this summer’s CTL Instructional Award Series.

Labyak brings his 23 years of professional industry experience to life in the classroom. He relates engineering project examples from General Motors in manufacturing and process engineering; Copper Range Company and Raytheon Missile Systems in project engineering; and Great Lakes Sound and Vibration in simulation analysis. All offer students an endless supply of practical applications to help understand engineering theory.

Labyak first developed new assignments and restructured machine design courses MET 3242 and MET 3451. Then, he developed new graduate courses: MET 5800 and MET 5801 for the mechatronics M.S. and online course MFGE 5200 for the manufacturing engineering graduate certificate.

In these courses, Labyak relates course theory to industrial applications of sheet metal design and fabrication, mining facility maintenance, and missile assembly processes. In addition, he uses examples from his family-owned farm in Ontonagon, where he maintains tractors and farm equipment. Vibrations, reliability and fatigue in mechanical components such as bearings, gears, drive systems, clutches and brakes provide examples students can easily grasp.

Labyak’s ability to explain where and how students will utilize the course content in their careers also makes him a great recruiter and advisor. “David often volunteers to meet with prospective students and their families,” says John Irwin, chair of MMET. “His industry knowledge in terms of engineering needs provides insight to guide MET students throughout their career paths.”

MET alum Mickala Kohtz ’21 explains how Labyak was effective in teaching MET 4660 CAE and FEA Methods. “He took the time to understand the way that I learned best and would walk me through difficult concepts. Dave was always willing to help his students, whether it was after class, the weekends, and even to lend a listening ear about job offers or Senior Design help.”

Likewise, former student Joshua Olusola says Labyak is very friendly and open to students anytime you find him available, even on Saturdays. “He gave sufficient in-class practice questions to ensure that the concept was understood before he assigned homework.” MET 5801 was Olusola’s first encounter with the Simulink software, but he transitioned smoothly using instructional labs prior to lab assignments. “I would say almost every student who had a course with Dave always jumped at an opportunity to take another with him due to his exceptional teaching technique and friendly personality. These traits indeed made students more open to learning.”

Dean Callahan recognizes Labyak’s ability to connect with students. “The personal relationships that Dave is able to develop with his students demonstrates the best parts of the high-tech, high-touch education that is Michigan Tech’s trademark. He is an inspiration to us all.”

Michigan Tech SWE section members and alumnae gather for a photo at Spring Forward 2022.

Nine student members of Michigan Tech’s section of the Society of Women Engineers (SWE) and their advisor, Gretchen Hein (MMET), recently attended Spring Forward, a professional development day in Kohler, Wisconsin, hosted by the SWE-Wisconsin.

Laura Kohler, Senior Vice President of Human Resources, Stewardship and Sustainability at Kohler Company gave the keynote address. She spoke about her career path, the importance of diversity, and leadership. 

Michigan Tech SWE Section members toured the Kohler Design Center after attending SWE-Wisconsin Spring Forward 2022

Mechanical Engineering alumna Jackie (Burtka) Yosick ‘14 also works at Kohler. She was on hand to discuss her work with engines and generators.

“We were also pleasantly surprised to meet Helene Cornils, director of the Advanced Development Kitchen and Bath Group at Kohler and the parent of a current Michigan Tech biomedical engineering student,” said Hein.

Two former Michigan Tech SWE Section presidents, Katie Buchalski ’19 and Andrea (Walvatne) Falasco ’12 were also present at the event. Buchlaski is an environmental engineering alumna now working at Ruekert-Mielke, where she designs municipal road and utility projects with a focus on modeling the stormwater runoff from individual sites to city-wide studies. Falasco, a mechanical engineering alumna, is lead mechanical engineer at Kimberly Clark, where she designs new equipment to make products that include Kleenex, Huggies, and Kotex. 

Numerous Michigan Tech students won SWE awards at the event, as well. One of those was biomedical engineering major Kathleen Heusser, who won a first place scholarship from the GE Women’s Network.

“Receiving the first-place 2022 GE Women’s Network Scholarship was an incredible honor,” said Heusser. “In addition to the tuition assistance it provides, the scholarship affirms my confidence in the value of my resume, my education, and my professional references, as well as my scholarship essay on what being an engineer means to me,” she explains. “The last paragraph in my essay shares how my work as an engineer will be motivated by my love of others in order to work hard–creating solutions to the problem of an individual, a company, or a society.

Another highlight of the day: Michigan Tech’s SWE section received the SWE-Wisconsin President’s Choice Award.

After the conference, each Michigan Tech student in attendance reflected on their participation and what they learned:

Aerith Cruz, Management Information Systems: “It was a great opportunity for Michigan Tech SWE members to bond and connect with one another. Being able to travel as a section and experience professional development together is a fulfilling experience. We are able to share learning opportunities and build long-lasting connections with one another. It is also incredibly fun getting to know each other while exploring the area.”

Kathryn Krieger, Environmental Engineering: “It was inspiring to hear the paths of various women, and the impacts they have made. I really enjoyed hearing about modern, female-centered design that benefits women in impactful ways–rather than the stereotypical ‘pink and shrink’ method.”

Natalie Hodge, Electrical and Computer Engineering (dual major): “Laura Kohler shared this quote in her presentation, attributed to Cassie Ho: ‘Don’t compare yourself to others. It’s like comparing the sun and the moon. The sun and the moon shine at their own time.’” 

Katherine Baker, Chemical Engineering: “I especially enjoyed attending the session, ‘Navigating Early Stage Careers: The First 10 Years’. It had a great panel that gave a ton of advice on how to advance as an engineer in the workplace.”

Maci Dostaler, Biomedical Engineering: “Women are necessary when it comes to inclusive design, which was covered during one of the sessions, ‘Breaking the Glass Ceiling’”.

Alli Hummel, Civil Engineering: “Laura Kohler talked about the importance of making time for your personal life and how that is necessary to succeed at work. She is a great example of a woman who succeeds in prioritizing both work and family life.”

Lucy Straubel, Biomedical Engineering: “I really enjoyed the whole experience. It was great to hear all the advice everyone else could give me. And making friends and memories was a bonus, too.”

Amanda West, Mechanical Engineering: “One of the things I liked most about the conference was keynote speaker Laura Kohler’s speech, where she mentioned the importance of having and maintaining relationships with your mentors, an important part in developing your career and professional skills.”

Kathleen Heusser, Biomedical Engineering: “In one session called Navigating Early Stage Careers: The First 10 Years, Tess Cain of DSM, among others, gave insightful tips about saying ‘no’ to a project or demand from management that’s just not feasible. She pointed out that how others accept your ‘no’ depends a lot on how you say it. You should use a response that includes ‘I can’t/Here’s why/Here’s what I would need to make this work’ in order to go in a doable direction with the project. And another inspiring quote, overheard during the Nonlinear Careers and the Versatility of Engineering Degrees panel, was that ‘100 percent of candidates are not 100 percent qualified.’ Raquel Reif of Kohler, in particular, stressed that already having expertise in a job field is not a necessary prerequisite to apply for the job you want.”

Fernando Ponta: The Wind Beneath My Wings/Sails/Turbines

“Since the emergence of the first windmill in ancient times, through the windmills of the middle ages, to the high-tech wind turbines of today, there has been an intimate relationship between the evolution of wind rotors and sailing rigs,” says Fernando Ponta.

Fernando Ponta shares his knowledge on Husky Bites, a free, interactive webinar this Monday, 3/28 at 6 pm. Learn something new in just 30 minutes or so, 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 3/28 at 6 ET? Grab a bite with Dean Janet Callahan and Fernando Ponta, the Richard and Elizabeth Henes Professor of Wind Energy. Joining in will be one of Dr. Ponta’s mechanical engineering PhD students, Apurva Baruah, who brings industrial experience to his research with Dr. Ponta. Baruah is also a member of the crew on Dr. Ponta’s J-80 sailboat, the Avanti Bianc.

“There’s no better way to understand the wind than trying to harness its power on sails,” says Baruah.

The Avanti Bianc: “I’ve been Apurva’s boat skipper since 2015, and his PhD advisor since 2017,” says Dr. Fernado Ponta. “We’re both part of Michigan Tech’s ‘Wind-Warriors’ team.”

During Husky Bites, Ponta and Baruah will explain the evolution of wind power technology from its beginnings until the current development of next-generation, advanced, mega-scale wind turbines. One aspect of their research involves modeling the wakes of many wind turbines operating in a huge wind farm. They’ll discuss the importance of understanding and modeling these wakes in order to optimize both offshore and inland wind farm performance.

“We’ll also share a brief review of our collaborative work with Sandia National Labs,” adds Baruah. “That includes the novel, aeroelastic-vortex-lattice codes we use to study cutting-edge wind energy technologies.”

At Michigan Tech, Ponta’s research team seeks to understand the detailed physics of a wind-turbine–from the rotor structure and aerodynamics, to turbine control and drivetrain electromechanics. 

“Since the emergence of the first windmill in ancient times, through the windmills of the middle ages, to the high-tech wind turbines of today, there has been an intimate relationship between the evolution of wind rotors and sailing rigs,” he says. “Ancient windmill designs used the principle of aerodynamic drag to produce the forces acting on the blades in the same manner that square rigs used drag to propel ships.”

“In a period of several centuries, sailing rigs progressively evolved into the use of sail arrangements that propel ships via the generation of lift force, which not only give ships the great advantage of going faster in the same conditions, but also of sailing partially into the wind,” adds Ponta. “All this technological experience translated into the evolution of wind rotors that also use lift as their physical mechanism for torque and power generation. In the case of a wind rotor, it has resulted in a dramatically higher efficiency of the conversion process from the kinetic energy of the wind, into mechanical power on the shaft.”

This parallel development was fundamental to the evolution of current wind energy technology, says Ponta. “The basic concept of the lift-driven wind rotor, conceived in the late middle-ages, is essentially the same as the high-tech wind turbines of today. The inherent energy efficiency of the lift generation process versus the generation of drag—with all its associated frictional losses—is the physical underpinning of this fundamental progress.”

Wind turbine blades average almost 200 feet long, and turbine towers average 295 feet tall—about the height of the Statue of Liberty.

Dr. Ponta and Apurva promise to interpret and explains these models for us during Husky Bites.

In modern times, a similar parallel can be traced between the optimization of the kinds of aerodynamic surfaces used in aeronautics, and the refinements of the latest generations of high-tech wind turbines, notes Ponta.

Over a period of years Ponta has developed a novel aeroelastic model for optimizing the rotor blades used in “smart” turbines and the collective control strategies of mega wind farms. The resulting modeling tool is now being applied by Sandia National Labs (SNL) for the study of the advanced lightweight rotors of their National Rotor Testbed (NRT) project. The result is a complete picture of how a wind turbine behaves under various conditions. Ponta’s modeling can be used to design blades and simulate the interaction of multiple wind turbine wakes in a wind farm, as well—particularly, the thousands of meters long wakes of the utility-scale megawatt turbines of today, and the super-turbines of tomorrow.

Dr. Ponta and his daughter enjoy skiing at Mont Ripley, Michigan Tech’s own ski area.

Dr. Ponta, how did you first get into engineering? What sparked your interest?

I’ve always been fascinated with science and technology, even when I was a kid. In my high school years, I attended what in my country of origin is called an industrial college, with a specialty in electronics. I started as a naval and mechanical engineering student, and then I decided to switch to a full career in mechanical engineering. With the years, I focused more and more into computational and theoretical fluid mechanics, in particular as they apply to the study of wind turbines and other renewable energy systems.

Hometown?

I was born in the city of Buenos Aires, Argentina, even though my family lives now in the Patagonia region. Curiously, they live at the same latitude that we are here in Houghton, but in the southern hemisphere. That is, the same temperatures but with a six-month shift!

What do you like to do in your spare time?

In summer, sailing and swimming. I own a sailboat which I skipper regularly in the regattas of the Onigaming Yacht Club, of which I’m a member of the directory board. In winter, I ski a lot at Mont Ripley. Alpine skiing is my favorite sport, and I’ve been skiing since I was in my teens in the Andes range in Patagonia. I lift weights all year round.

Apurva, how did you first get into engineering? What sparked your interest?

Apurva is passionate about aviation, too. “Since 2017 I’ve been visiting the EAA AirVenture, a summer air show and gathering of aviation enthusiasts in Oshkosh, Wisconsin at Oshkosh.”

I’ve been fascinated with aircraft from a very young age. I had an amazing physics teacher throughout grade school and figured engineering was the path forward in order to work with airplanes.

During my undergrad years, I just naturally ‘flowed’ towards fluids and aerodynamics. After a few years working in industry, I decided to pursue a graduate degree at Tech. Our research in wind turbines and their wakes in a wind farm is a perfect blend of my interests.

Hometown?

I was born and raised in Mumbai, India. My mom’s terrified yet excited to visit the Keweenaw! She frequently catches our blizzard-y days by watching the HuskyCam feeds!

Any hobbies?

Thanks to Dr. Ponta, I’ve found an immense passion for sailing. It’s an important aspect of our summer ‘research’. I also frequent Michigan Tech’s Student Development Center, aka “the SDC” for racquet sports, including tennis, badminton, and table tennis, and the shooting range. I’m the range safety officer for Michigan Tech’s Competition Rifle team.
