Guy Meadows: Shipwrecks and Underwater Robots

Guy Meadows: “I love being on the waters of the Great Lakes and the oceans⁠—and having an engineering career that allows me to do what I love.

Guy Meadows generously shared his knowledge at 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.

Guy Meadows uses an underwater robot to chart new territories in the field of underwater exploration. But not just any old robot—one of the world’s best.

Its name is Iver3, and it has two dual processor computers on board, Wifi, GPS, water flow and speed of sound sensors, and the latest in sonar technology. It can dive 330 feet and cover 20-plus miles of water on missions up to 8 hours. It also has a high definition camera, lights and a satellite phone. These combined features make Iver an impressive research tool.

The IVER3. Consider it a robotic Aquaman. “Iver performs like a superhero,” says Meadows.

With Iver, Meadows and his team are able to provide ultra-high resolution acoustic images underneath the waters of the Great Lakes. “Whether it’s tracking underwater features, looking at shipwrecks, or mapping trout spawning beds, we can do this all much more precisely and in much greater detail than was ever possible,” he says.

Meadows is director of the Marine Engineering Laboratory, and the Robbins Professor of Sustainable Marine Engineering at Michigan Tech. His work with Iver is cutting edge. “Iver can obtain a ‘survey quality’ map of a swath of the bottom of Lake Superior,” he explains. “The map size depends on the altitude of the robot above the lake floor, but at ten meters above the bottom you can map an entire football field.”

“What we’re doing is seeing with sound waves. Acoustic energy shines on the target and illuminates it for us. Navy research vessels use active remote sensing, too,” he adds. “But we can see a lot more clearly with Iver.”

Here is the John J. Audubon, which sank in Lake Huron in 1854 in 180 feet of water and now within the NOAA’s marine sanctuary boundaries. “We’re seeing with sound waves,” Guy Meadows explains. “Acoustic energy illuminates the target and allows a higher resolution image of the shipwreck and its acoustic shadow.”

Michigan Tech students learn how to program Iver as part of their many classes onboard Agassiz, the university’s research vessel. “If we set up the geometry just right, we can get the highest possible quality sonar image,” Meadows explains.

“When we go out to look at shipwrecks in Lake Superior, we program Iver to fly a prescribed distance from the bottom of the lake, and a prescribed distance from the vessel. We can see both the image of the target vessel, and its acoustic shadow,” says Meadows. “The images are fantastic, but the shadows also provide a great deal of valuable information and detail.”

Q: When did you first get into engineering? What sparked your interest?

“I was born and raised in the City of Detroit. I went to Detroit Public Schools, and when I went to college I had to work to make ends meet. I got a job as a cook in the dorm, and and eventually worked my way up to lead cook. I was cooking breakfast for 1,200 people each morning. One of my fellow classmates was studying engineering, too. He had a job working for a professor doing research on storm waves and beaches. I had no idea I could be hired by a professor and get paid money to work on the beach! I quit my job in the kitchen soon after, and went to work for that professor instead. I had been a competitive swimmer in high school, and the beach was where I really wanted to be. When I graduated with my degree, having grown up in Detroit, I went to work for Ford. I have to thank my first boss for assigning me to work on rear axle shafts. After about two months, I called my former professor, to see if I could come back to college.

My advice for students just starting out is to spend your first year exploring all your options. Find out what you really want to do. I had no idea I could turn a mechanical engineering degree into a job working on the beach. Turns out, I could⁠—and I’m still doing it today.

Q: What do you like to do when you’re not on the beach or out on the water?

Having grown up in Detroit, I have had the opportunity to live, work and grow in a very diverse community. While as a faculty member at the University of Michigan, I was part of a great team that started the M-STEM Academies and became its founding director. The M-STEM mission is “to strengthen and diversify the cohort of students who receive their baccalaureate degrees in science, technology, engineering, and mathematics (STEM), with the ultimate goal of increasing the number and diversity of students who are well prepared to seek career opportunities or to pursue graduate or professional training in the STEM disciplines in the new global economy.” This effort has been a very important part of my journey.

Becky Ong: Color-Changing Potions and Magical Microbes

Miscanthus, otherwise known as Switchgrass, a perennial grass, can be used for making biofuels. “But plant materials are very complex,” says Dr. Rebecca Ong. “We’ve only scratched the surface of what is in there. We have much more to learn.”

Dr. Becky Ong generously shared her 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.

Fungus Breath? It’s a good thing!

Enter the magical world of herbology and potions with Dr. Becky Ong. Learn how to make your own color-changing potion and use it to find the best conditions to generate and collect fungus breath. Discover the science behind the magic, what makes plants and microbes so cool. 

Dr. Becky Ong in her lab at Michigan Technological University. She is both a biologist and a chemical engineer.

Dr. Ong, an assistant professor of chemical engineering, runs the Biofuels & Bio-based Products Lab at Michigan Tech, where she and her team of student researchers put plants to good use.

“As engineers we aren’t just learning about the world, but we’re applying our knowledge of the world to make it a better place,” she says. “That is what I love. As a chemical engineer, I get to merge chemistry, biology, physics, and math to help solve such crazy huge problems as: how we’re going to have enough energy and food for everyone in the future; how we’re going to deal with all this waste that we’re creating; how to keep our environment clean, beautiful and safe for ourselves and the creatures who share our world.”

Dr. Ong, a born Yooper,  is a Michigan Tech alumna. She graduated in 2005 with two degrees, one in Biological Sciences, and the other in Chemical Engineering. She went on to Michigan State University to earn a PhD in Chemical Engineering in 2011. Growing up, she was one of the youngest garden club enthusiasts in northern Michigan, a science-loving kid who accompanied her grandparents to club events like “growing great gardens” or “tulip time.” When she wasn’t tending the family garden, she was “mucking about in nature” learning from parents who had both trained as foresters.

“We conduct many small-scale experiments in the lab—on a variety of plant materials grown under different environmental conditions. We want to determine just how those conditions affect the production of biofuels.”

Q: When did you first get into engineering? What sparked your interest?

I first became interested in engineering in high school when I learned it was a way to combine math and science to solve problems. I loved math and science and thought that sounded brilliant. However, I didn’t understand at the time what that really meant. I thought “problems” meant the types of problems you solve in math class. Since then I’ve learned these problems are major issues that are faced by all of humanity, such as: How do we enable widespread access to clean energy? How do we produce sufficient amounts of safe vaccines and medicine, particularly in a crisis? How do we process food products, while maintaining safety and nutritional quality? As a chemical engineer I am able to combine my love of biology, chemistry, physics, and math to create novel solutions to society’s problems. One thing I love about MTU is that the university gives students tons of hands-on opportunities to solve real problems, not just problems out of a textbook (though we still do a fair number of those!). These are the types of problems our students will be solving when they go on to their future careers.

Q: Tell us about yourself. What do you like to do outside the lab?

I’m a born Yooper who grew up in the small-town northern Lower Peninsula of Michigan and came back to the UP for school.

I love the Copper Country and MTU students so much, I managed to persuade my husband to come back to Houghton 5 years ago. Now I live near campus with my husband, 4-year-old daughter, our Torbie cat and our curly-haired dog.

We read science fiction and fantasy stories; play board games; kayak on the canals and lakes while watching for signs of wildlife; make new things out of yarn, fabric, wood, and plastic (not all at the same time)—and practice herbology (plants and plant lore) and potions in the garden and kitchen.

Biofuels and Dry Spells: Switchgrass Changes During a Drought

High yields. A deep root system that prevents soil erosion and allows for minimal irrigation. The ability to pull large amounts of carbon out of the air and sequester it in the soil. Beneficial effects on wildlife, pollination, and water quality. Perennial grasses, such as switchgrass and elephant grass, are wonderful in many ways and especially promising biofuel feedstocks. But that promise, a team of researchers discovered, may evaporate during a drought.

“The characteristics of any living organism are linked to their genetics and the environment they experience during growth,” says Rebecca Ong, an assistant professor of chemical engineering at Michigan Technological University. “Bioenergy production is no different. It’s a chain where every link, including the feedstock characteristics, influences the final product—the fuel.”

Ong is both a chemical engineer and a biologist. She holds a unique perspective on how the bioenergy system fits together, which comes in handy, especially now, in light of a recent puzzling discovery.

“Plants have lower biomass yields during a drought. You understand this when you don’t need to mow your lawn after a dry spell,” she explains. “The same is true with switchgrass. Besides the expected effect on crop yields, we were completely unable to produce fuel from switchgrass—using one of our standard biofuel microbes—grown during a major drought year.”

“At the lab scale this is an interesting result. But at the industrial scale, this could potentially be devastating to a biorefinery,” she says.

Ong, her research team, and colleagues within the Great Lakes Bioenergy Research Center (GLBRC), a cross-disciplinary research center led by the University of Wisconsin–Madison, are making efforts to understand, pulling in researchers from across the production chain to study the problem. 

Ong is the only Michigan Tech faculty member in the GLBRC. “Our team was able to identify some of the compounds formed in the plant in response to drought stress, contributing to the inhibition. But plant materials are very complex. We’ve only scratched the surface of what is in there. We have much more to learn.”

The first step, she says, is to understand what inhibits fuel production. “Once we know that, we can engineer solutions: new, tailor-made plants with improved characteristics, as well as modifications to processing, such as the use of different microbes, to overcome these issues.”

Ong points out that in the U.S., gasoline is largely supplemented with E10 ethanol, derived from sugars in corn grain. However renewable fuels can be produced from any source of sugars—including perennial grasses, which if planted on less productive land do not conflict with food production.

“Ultimately, if we are to replace fossil energy in the long term, we need a broad alternative energy portfolio,” says Ong. “We need industry to succeed. We are engaging in highly collaborative research to ensure that happens.”

Brad King: Space, Satellites and Students

Pictured: the Auris signal trace, soon to be explained by Dr. Lyon (Brad) King on Husky Bites.

Lyon (Brad) King shares his knowledge on Husky Bites, a free, interactive webinar this Monday, May 18 at 6 pm. Learn something new in just 20 minutes, with time after for Q&A! Get the full scoop and register at mtu.edu/huskybites.

Oculus deployed! In June 2019 Michigan Tech alumnus and Air Force Research Laboratory Space Systems Engineer Jesse Olson, left, celebrates with Aerospace Enterprise advisor Brad King. King’s son Jack was also on hand for the momentous occasion of the launch.

Turning dreams into reality is a powerful motivator for Lyon (Brad) King. He’s the Richard and Elizabeth Henes Professor of Space Systems in the Department of Mechanical Engineering-Engineering Mechanics, and leader of Michigan Tech Aerospace—a collection of research, development, and educational labs dedicated to advancing spacecraft technology.

King specializes in spacecraft propulsion — and the launching of student careers. He mentors a large team of graduate students in his research lab, the Ion Space Propulsion Lab, where teams develop next-generation plasma thrusters for spacecraft. Off campus, at the MTEC SmartZone, King is cofounder and CEO of the fast-growing company, Orbion Space Technology.

As the founder and faculty advisor of Michigan Tech’s Aerospace Enterprise, King empowers undergraduate students to design, build, and fly spacecraft, too. One of the team’s student-built satellites (Oculus) is now in orbit; their second small satellite (Stratus) is due to launch in March 2021, and a third (Auris) now in process.

“The desire to explore space is what drives me. Very early in my studies I realized that the biggest impediment to space exploration is propulsion. Space is just so big it’s hard to get anywhere. So I dedicated my professional life to developing new space propulsion technologies.”

Professor Lyon (Brad) King, Michigan Tech

King has served as the Enterprise advisor ever since a couple of students came to him with the idea to form a team nearly two decades ago. “My current role now is more that of an outside evaluator,” he says. “The team has taken on a life of its own.”

Like all Enterprise teams at Michigan Tech, Aerospace Enterprise is open to students in any major. “It’s important for students to learn how to work in an interdisciplinary group,” says King. “In the workplace, they will never be on a team where every member has the same expertise. To design, build, manage and operate a satellite requires mechanical, electrical, computer science, physics, materials, everything — it really crosses a lot of boundaries and prepares them for a career.”

Adds King: “Michigan Tech has a history and reputation for hands-on projects, particularly its Enterprise Program. Our students don’t just write papers and computer programs. They know how to turn wrenches and build things. That’s been deeply ingrained in the University culture for years.” 

Last, but not least: “Aerospace Enterprise has a leadership and management hierarchy that is self-sustaining,” says King. “Current leaders are constantly working to mentor their successors so we have continuity from year-to-year.” 

“Dr. King provides excellent mentoring and high-level direction, but does not give students all the answers. It’s up to the students to figure it out. We work in small teams, which forces us to take on more responsibility. We’re thrown off the deep end. It’s hard, but worth it.”

The New Space Era

Commercialization is driving aerospace expansion in Michigan and across the nation. “We were ahead of it,” says King. “We certainly were feeding it and played a part in causing it. MTU’s products — which are our graduates — are out there, making this happen.” Aerospace Enterprise alumni are engineers, managers, technology officers and research scientists in a diverse array of aerospace-related industries and institutions, from the U.S. Army, U.S. Air Force and NASA to SpaceX, both startups and major manufacturers. King himself has hired several of his former students at Orbion Space Technology.

“The desire to explore space is what drives me,” says Lyon (Brad) King, Henes Professor of Space Systems at Michigan Technological University

Q: When did you first get into engineering? What sparked your interest?

A: I have always been interested in building things — long before I knew that was called “engineering.” I don’t recall when I became fascinated with space but it was at a very early age. I have embarrassing photos of me dressed as an astronaut for halloween and I may still even have an adult-sized astronaut costume somewhere in my closet — not saying. The desire to explore space is what drives me. Very early in my studies I realized that the biggest impediment to space exploration is propulsion. Space is just so big it’s hard to get anywhere. So I dedicated my professional life to developing new space propulsion technologies. There is other life in our solar system. That is a declarative statement. It’s time that we find it. The moons of Jupiter and Saturn hold great promise and I’m determined to see proof in my lifetime.

Q: Can you tell us more about your growing up? Any hobbies?

A: I was born and raised just north of Houghton (yes, there actually is some habitable environment north of Houghton). I received my BS, MS, and PhD from the University of Michigan. I spent time traveling around the country working at NASA in Houston, NIST in Boulder, and realized that all of my personal hobbies and proclivities were centered around the geography and climate of northern Michigan. I returned in 2000 and began my career as a professor at MTU. I enjoy fishing, boating, hockey, and spent more than 15 years running my dogsled team all over the Keweenaw Peninsula.


Michigan Tech’s Three Student-Built Satellites

OCULUS-ASR, a microsatellite now in orbit, provides new info to the Air Force. “It is the first satellite mission dedicated to helping telescope observatories understand what they are imaging using a cooperative target. “It’s a very capable little vehicle. There’s a lot packed into it.”

Aerospace Enterprise rendering of Stratus, a miniaturized satellite developed by the team. It will be launched from the International Space Station in March 2021.

Not hard to see how CubeSats get their name. Stratus is a 3U spacecraft, which means it’s composed of three units. This photo was taken in fall 2019.

STRATUS, a miniaturized satellite, will image atmospheric clouds to reconcile climate models. It’s funded by NASA’s Undergraduate Student Instrument Program and the CubeSat Launch Initiative. STRATUS will be carried to the International Space Station inside the SpaceX Dragon cargo capsule by a Falcon 9 rocket. The Dragon will dock to the ISS where STRATUS will be unloaded by the crew. STRATUS will then be placed in the Kibo Module’s airlock, where the Japanese Experiment Module Remote Manipulator System robotic arm will move the satellite into the correct position and deploy it into space. All this on March 21. Stay tuned!

Aerospace Enterprise rendering of its newest microsatellite, Auris, now in the works.

AURIS, a microsatellite, is designed to monitor and attribute telecommunications signals in a congested space environment. Funding comes from the Air Force Research Lab (AFRL)’s University Nanosatellite Program.

My Mother’s Hands

Author's hand outstreched over a jigsaw puzzle on a card table, with Husky dog far in the background,  to show her knuckly fingers and her mother's ring

Okay, so I have my mother’s hands. May she rest in peace. For her fiftieth birthday, many years ago, us four daughters decided to get her a nice piece of jewelry. We shopped, and together we tried out a bunch of rings. 

My other sisters’ hands are more delicate than mine. My hands call to mind a worker, or farmer, or crafter, hands with knuckles and calluses. While shopping, we decided my hands were the best model for the ring for our mother, and so I was the odd model on this shopping expedition, with the jewelry merchants looking at me with eyebrow askance. With their beautifully groomed hands they examined mine, seeking different shapes and kinds of rings to try on, to find something that would balance my knuckly fingers.

One day, many years later, I was inside watching some commotion in the driveway. My stepson needed to add water to his radiator. The cap was stuck. He, his dad, and a friend were standing around the car, hood up, scratching their heads.

Watching this from inside the house, I figured it wouldn’t hurt to have a go. Grabbing a kitchen towel, I wandered outside. Approaching the car, I asked about the problem, then casually swooped in with my towel and my mother’s hands. 

I doubled up the kitchen towel over the four-pronged, blunt radiator knob, grasped it with my dominant hand, then added my other hand over top, all fingers locking in to seal the strength. I locked wrists, forearms, elbows to my shoulders and slowly rotated my torso. Of course the cap gave way. I straightened up, pulled off the towel, brushed off the thanks, and walked back into the house.

From my dad, I got the engineer’s outlook, and from my mom these strong, wise hands. From both of them, I was given ample opportunity to try anything, fail, and try again. 

Where did I learn to do this, I wonder? To not use my wrist and hand alone? The feeling wasn’t pride exactly, but closer to gratitude—for my parents who taught me to roof and landscape, and to use my head to solve problems. From my dad, I got the engineer’s outlook, and from my mom these strong, wise hands. From both of them, I was given ample opportunity to try anything, fail, and try again. 

I am now an engineering professor and have been given tremendous responsibility as a dean. Problem solving is what we teach engineering students, mingled with theory and design. We also give them ample opportunity to learn by doing. Yet, the largest part of their problem-solving “knack,” will come from the projects they already did, well before arriving in college.

All the tasks given to a child, the forced labor assigned to teens, and the challenges you take on as an adult, add up. I remember Dad giving instructions with no more detail than, “Take down this wall,” and I could not have wished for a better engineering teacher. We lost him too soon, when he was just 48, to cancer.

I wear her ring now and it fits me well. I could never fill her shoes, but I can fill her gloves. Around the blister earned from raking this weekend and the snagged skin from a thorn, I look at my mother’s hands and imagine them still shuffling and playing cards, the way she did when our work was through. 

My mother passed ten years ago this month. Miss you Mom! Still feel your strong—and gentle—touch.

Do you have your own stories about your mom, or dad, to share? Please email me. I would love to hear them, callahan@mtu.edu.

John Gierke: How the Rocks Connect Us

John Gierke shares his knowledge on Husky Bites, a free, interactive webinar this Monday, May 11 at 6 pm. Learn something new in just 20 minutes, with time after for Q&A! Get the full scoop and register at mtu.edu/huskybites.

John Gierke stands with water behind him, on the shore of Portage Canal.
Water was John Gierke’s first love growing up. Now he is Professor and Chair of the Department of Geological and Mining Engineering and Sciences at Michigan Tech, specializing in hydrogeology. Here he stands at the shore of Portage Canal, on campus.

A self-professed “Yooper graduate of the school of hard rocks,” John Gierke chairs the Department of Geological and Mining Engineering and Sciences (GMES) at Michigan Technological University. He’s also an alumnus, earning a BS and MS in Civil Engineering, and a PhD in Environmental Engineering, all at Michigan Tech.

Q: How do the rocks connect us?

A: The geology of the Keweenaw and Western Upper Peninsula is quite unique and different than the Eastern Upper Peninsula and Lower Peninsula. The geology of the Keweenaw is more exposed and accessible. The experience of spending time in the Copper Country is enhanced if you understand more about the forces of nature that formed this beautiful place. While geologists are knowledgeable in identifying rocks, their truest natures are also wrapped in a yearning to be outdoors, exceptional observation skills, and insatiable curiosity to understand Earth processes. The processes that led to the geological formations that lie beneath us–and shaped our landscapes–are what dictated many of the natural resources that are found where each of us live.

Q: When did you first get into engineering? What sparked your interest?

A: I began studying engineering at Lake Superior State College (then, now University) in the fall of 1980, in my hometown of Sault Ste. Marie. In those days their engineering program was called: General Engineering Transfer, which was structured well to transfer from the old “Soo Tech” to “Houghton Tech,” terms that some old timers still used back then, nostalgically. I transferred to Michigan Tech for the fall of 1982 to study civil engineering with an emphasis in environmental engineering, which was aligned with my love of water (having grown up on the St. Mary’s River).

Despite my love of lakes, streams, and rivers, my technical interests evolved into an understanding of how groundwater moves in geological formations. I used my environmental engineering background to develop treatment systems to clean up polluted soils and aquifers. That became my area of research for the graduate degrees that followed, and the basis for my faculty position and career at Michigan Tech, in the Department of Geological and Mining Engineering and Sciences (those sciences are Geology and Geophysics). My area of specialty now is Hydrogeology.

Q: Can you tell us more about your growing up? Any hobbies?

A: Growing up I fished weekly, sometimes daily, on the St. Mary’s River throughout the year. Sault Ste. Marie is bordered by the St. Mary’s River on the north and east. In the spring-summer-fall, I fished from shore or a canoe or small boat. In the winter, I speared fish from a shack just a few minutes from my home or traveled to fish through the ice in some of the bays. I was a fervent bird hunter (grouse and woodcock) in the lowlands of the EUP, waterfowl in the abundant wetlands, and bear and deer (unsuccessfully until later in life). I now live on a blueberry farm that is open to the public in August for U-Pick. I used my technical expertise to design, install, and operate a drip irrigation system that draws water from the underlying Jacobsville Sandstone aquifer.

The series kicks off on Monday, May 11 with a session from GMES professor and chair John Gierke, a self-professed “Yooper graduate of the school of hard rocks.”

In his Husky Bites session, “How the Rocks Connect Us,” Gierke will talk about how the geology of the Keweenaw is more exposed and accessible. “The experience of spending time in the Copper Country is enhanced if you understand more about the forces of nature that formed this beautiful place,” he says. “The processes that led to the geological formations that lie beneath us and shaped our landscapes are what dictated many of the natural resources that are found where each of us live.” Gierke was born in the EUP (the Soo, aka Sault Sainte Marie) and graduated from Michigan Tech. He will provide practical explanations for why the mines are oriented as they are, where water is more prevalent—and the geological features that lead to waterfalls. You can read all about it here.

Other guests on Husky Bites include engineering faculty L. Brad King, Gordon Parker, Rebecca Ong, Guy Meadows, Andrew Barnard, Tony Pinar, Daisuke Minakata, Jeremy Bos, Joe Foster, Smitha Rao, and Steve Kampe.

Did You Sign Your Name on This Door?

Now, I live close to campus, in a stately banker’s home on Houghton Avenue.

We bought Mrs. Frim’s house (Mrs. Frimodig) in 2018. At one point, the home had been famously rented out to Michigan Tech alumni, many who signed their names on the attic door. Widowed after Mr. Frim unexpectedly passed at an early age, Mrs. Frim earned a living in this way.

Roger Smith, an engineering alumnus who grew up in Houghton, weeded for Mrs. Frim as a young man. I met him at Reunion 2018; he relayed to me that “She had a nice side garden in the south-east backyard – with lots of gladiolas. I spent a lot of hours toiling there…at 15-25 cents an hour!”

Sadly, that poor side garden has turned into goutweed heaven—an invasive species. I started attacking it yesterday. I read that I can “exhaust it,” or dig it up! So I exhausted myself digging it up and only made a small start; it will take the next two years to recover that patch of garden. Ha-ha, says the goutweed…. 

Did any of you happen to carve your name on the attic door? If so, please let me know! Take a look at all five panels, for a closer look. Maybe you’ll see someone you know!

If you find your name, or know more about this door, please email me. I would love to hear the stories; callahan@mtu.edu.

Everything has to be made out of something. The question is out of what—and how do we make it?

Ferrosilicon inoculant is added to a stream of liquid iron. Sparks fly as the inoculant reacts with the liquid iron.

These are the questions engineers at Michigan Tech have been asking since the university’s founding in 1885. It’s the task that graduates from the Department of Materials Science and Engineering (MSE) have excelled at since its inception as one of the two founding departments at the Michigan School of Mines in Michigan’s Upper Peninsula in 1885. Back then, the department was known as Metallurgy, and its focus was on ways to extract valuable metals, such as copper or iron, from their naturally occurring states within minerals and underground deposits.  

Today the discipline of Materials Science and Engineering finds ways to use the fundamental physical origins of material behavior—the science of materials—to optimize properties through structure modification and processing, to design and invent new and better materials, and to understand why some materials unexpectedly fail. In other words, the engineering of materials.  

The Michigan Tech campus is located on the Portage Canal near Lake Superior.

Contemporary materials engineers (aka MSEs) work with metals and alloys, ceramics and glasses, polymers and elastomers; electronic, magnetic, and optical materials; composites, and many other emerging materials. That includes materials such as 2-D graphene, nanomaterials and biomaterials, materials that have been 3D printed or additively manufactured, smart materials, and specialized sensors.

Materials Science and Engineering (MSE) connects and collaborates with many other disciplines. The products and processes developed by MSEs are used by others to make new or improved products.

Materials Science and Engineering is inherently interdisciplinary—students interact and collaborate with students and scientists in other engineering disciplines, and also science disciplines, including chemistry and physics. 

Despite its legacy and historical central importance to all engineering endeavors, the materials discipline is relatively small compared to other engineering disciplines such as mechanical, electrical, civil, and chemical engineering. In fact, many universities do not have stand-alone materials departments.

“But this is one of the best aspects of being an MSE,” says Michigan Tech MSE Department Chair Steve Kampe, “Class sizes are small, and students build strong networks with classmates, the faculty and staff, and with likeminded colleagues from other universities from around the world,” he says. “It enables strong learning and collaborative environments with lots of personalized interaction and one-on-one mentoring.”

Not only is Kampe a member of the Michigan Tech faculty, he is also an alumnus, earning a Bachelor’s, Master’s, and PhD in Metallurgical Engineering, all from Michigan Tech. He joined academia after working in the corporate research laboratory for a major aerospace company, where scientists and engineers developed new products and technologies for the company’s future.

At Michigan Tech, the MSE department manages the university’s suite of scanning electron and transmission electron microscopes, including a unique, high resolution scanning transmission FEI Titan Themis. The facility also maintains excellent X-ray diffraction, X-ray photoelectron spectroscopy, and Auger electron spectroscopy capabilities. In the university’s Institute of Material Processing (IMP), also led by MSE faculty, processing capabilities include melt processing, deformation processing, microelectronic fabrication, and particulate (powder)-based processing capabilities. All students use these world-class facilities—even as undergraduates.

Students at Michigan Tech can join one of 24 Enterprise teams on campus to work on real projects, for real clients. Students invent products, provide services, and pioneer solutions. Advanced Metalworks Enterprise (AME) is a popular enterprise among MSE students. Small groups within the AME team take ownership of metallurgical manufacturing projects, working closely with industry sponsors.

“Being on an Enterprise team helps students build a résumé, develop teamwork skills, form professional relationships, and learn what to expect in the workforce,” says Kampe. “We’re grateful for our corporate sponsors’ help in offering students an opportunity to take textbook skills from the classroom and apply them in practical ways, to experiment, and get results.”

MSE students also get involved in Materials United (MU), a student professional organization that exposes them to all aspects of Materials Science and Engineering—learning about industry, sharing research, developing personal skills, participating in professional societies, and traveling to international conferences. 

As one example of student success, MSE students from Michigan Tech won first place in ASM International’s Undergraduate Design Competition the last two years in a row, based on entries from their capstone senior design projects. Last year, the winning entry was based on a project entitled “Cobalt reduction in Tribaloy T-400” sponsored by Winsert, Inc. of Marinette, Wisconsin.

“Winsert currently uses an alloy similar to Tribaloy T-400, a cobalt-based alloy, in the production of internal combustion engine valve seats,” Kampe explains. “Cobalt is an expensive element with a rapidly fluctuating price, due to political instability in the supplier countries. The alloy contains approximately 60 wt. percent cobalt, contributing significantly to its price. There are also serious sustainability and environmental implications associated with the use of cobalt—both positive and negative,” he says. “Cobalt is one of the elements used as an anode material for lithium ion batteries that are now under heavy development for electric vehicles.” 

The student team investigated the replacement of cobalt with other transition elements such as iron, nickel, and aluminum using thermodynamic modeling. “All MSE senior design projects at Michigan Tech use advanced simulation and modeling tools, experimental calibration, and statistical-based analyses of the results,” notes Kampe. “The Winsert project utilized software called CALPHAD (Pandat) with a form of machine learning —Bayesian Optimization—to identify new and promising alloy substitutions. Such advanced techniques are rarely introduced at the undergraduate level in most other MSE programs.”

“Our department’s small size allows meaningful student involvement in hands-on laboratory activities, personal access to facilities, real participation in leading-edge projects, and close networking with peers, faculty and staff, alumni, and prospective employers,” adds Kampe. “The benefits of being a part of a strong professional network continues after graduation. Our strong learning community becomes our students’ first professional network after they graduate. It gives them a strong early foundation for a great career.”

Due to the importance of materials to the success of nearly all engineered products, MSEs enjoy employment opportunities in a wide range of industries and in a variety of functions. For example, MSEs are prominent within the automotive, aerospace, electronics, consumer products, and defense industries, performing duties such as new material design, material substitution and optimization, manufacturing science, and material forensics, such as material identification and failure analyses.

“There are also rich opportunities in corporate and government research and development, since new products and functionalities often start with advancements in our understanding of materials, or in our ability to process them,” says Kampe. “MSE graduates from Michigan Tech enjoy nearly 100 percent placement at graduation due not only to the reputation of the department, but also due to the fact that just about all engineering-oriented companies rely on materials for their products.”
