Mike Roggemann: Mixing Lasers with the Atmosphere

“A mirage is light from the sky that is refracted back to your eye, with turbulence thrown in to make it shimmer,” says Michigan Tech Professor Emeritus Mike Roggeman. Image of ship on horizon, taken in Dubrovnik. Credit: Thriol, Flickr.

Michigan Tech Professor Emeritus Mike Roggemann

What are you doing for supper this Monday night 10/10 at 6 ET? Grab a bite with Associate Dean Leonard Bohmann and Mike Roggemann, professor emeritus of Electrical and Computer Engineering at Michigan Tech. The two worked together for many years as colleagues in the ECE Department.

Note: Dr. Bohmann will fill in as host for Husky Bites on Monday, October 10. He is Michigan Tech’s associate dean for academic affairs in the College of Engineering, and also a professor of Electrical and Computer Engineering.

According to the National Weather Service, turbulence is an irregular motion of the air resulting from eddies and vertical currents, associated with fronts, wind shear, and thunderstorms. It can be chaotic, irregular, random, and swirling. “That’s the mechanical form of turbulence,” notes Roggemann. “I’m interested in the optical effects of turbulence,” he says.

“Think back to a hot summer day, when you’ve seen a car driving down a road that’s shimmering in the heat,” he says. “There are some really interesting atmospheric optic effects. A huge amount of work has been done to understand the nature of these effects and how to mitigate them—due to the practical impact on a huge number of things we really want to work.”

Over the years at Michigan Tech, Roggemann has put Michigan Tech’s north woods location on Lake Superior to great use for his research. One of his goals: to extend the range and understand the performance of imaging and laser systems in any kind of weather. 

“We’ve got it all here—remote locations, blizzards, thunderstorms, heat waves,” he says. “The UP is uniquely suited to the job.” 

Data from some of Dr. Roggemann’s previous research.

Roggemann and his research team at Michigan Tech developed a laser communications testbed to evaluate adaptive optics algorithms, installing it atop an eight-story building in the nearby city of Hancock. The system directed a laser beam 3.2 kilometers to a receiver located on the roof of the Dow Building on campus. They spent several years monitoring atmospheric turbulence, scattering, and weather to understand how such factors fluctuate in the real world.

Free space laser communications systems send lasers through air. One challenge is that it’s not really free space—it’s air. “Atmosphere changes and turbulence can make the laser beam wander,” says Roggemann.  “Some technologies exist to partially mitigate these effects, but none are perfect,” he says.

Channel fading is one problem, and sometimes deep channel fading. If it goes down too low, the communication link can be broken. Roggemann and his research team of students designed and tested various ways of solving this problem to make laser communications more stable and reliable—and be able to achieve the highest possible channel capacity.

One thing they tried: using adaptive optics (AO) on the transmitter, to steer and focus the laser beam on the receiver aperture. The result was less fluctuation, which reduced fading. They discovered another benefit—an increase in received optical signal power.

A fellow of Optica (OSA) and fellow of SPIE, Roggeman is coauthor of the book “Imaging Through Turbulence,” and has authored or coauthored over sixty journal articles and over fifty conference papers, many relating to laser communication. Some of his other research interests include optical remote-sensing system design and analysis, and signal and image processing.

“Lasers and the atmosphere don’t mix all that well.”

Mike Roggemann

Before joining the faculty at Michigan Tech, Roggemann was an associate professor of engineering physics at the Air Force Institute of Technology, Wright-Patterson AFB, in Ohio. 

He earned a BS in Electrical Engineering at Iowa University, and an MS and PhD in Electrical Engineering at the Air Force Institute of Technology. Along the way he worked as an electro-optics program manager at Wright Laboratories, Wright-Patterson AFB, in Ohio, and an imaging researcher at the Phillips Laboratory, Kirtland AFB, in New Mexico. 

When you spot this sign, you’re in the right place to witness the Paulding Light.

Prof. Roggemann mentored and advised countless electrical engineering students over the years, many of whom earned their doctorate degrees. In addition to conducting research and teaching in photonics and optics, Prof. Roggeman served as the ECE department’s graduate director, no small feat. At any given time, the ECE department has about 50-plus PhD students and 140-plus MS students. 

In 2011, a group of Roggemann’s research students at Michigan Tech, led by then PhD student Jeremy Bos, examined the mysterious Paulding Light phenomena taking place in Paulding, Michigan. Their goal: separate fact from fiction.

Spoiler Alert: “The Paulding Light can be explained as a refraction of headlights from an inversion over the valley,” says Roggemann.

“If not for the students, why are we here?”

Dr. Bohmann was serving as interim ECE department chair when the position for the College of Engineering associate dean opened up. “I kind of like the administrative side of things, so I applied for the job,” he says.

It gives him the chance to participate in professional service, including volunteering as a program evaluator for ABET, the organization that accredits engineering programs (including Michigan Tech’s). He’s an ABET commissioner, working with ABET for close to 20 years now. 

But how did Dean Bohmann end up at Michigan Tech in the first place? The year was 1988, early October. 

“Janeen and I decided to make the long drive to Houghton to see what it was like at Michigan Tech,” he recalls. “That night we stayed at McLain State Park campground. We got up in the morning, looked out of the tent, and saw snowflakes in the air.” 

The rest is history. “We decided to move to the Great North Woods, to live near the shore of Lake Superior. This August it will have been 33 years!”

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

I was fascinated by the space program as a boy in the 1960s and 1970s, and resolved to go to college and major in science or engineering to be a part of it.

Hometown?

I was born and raised in a small town in Iowa. After high school I went to Iowa State, and entered the Air Force upon graduation. I had some interesting assignments while on active duty, and got both my MSEE and PhD. I spent my last five years on active duty as a professor at the Air Force Institute of Technology. Upon retiring from the Air Force I joined the faculty at Michigan Tech, in the ECE department. I retired from academic life in June 2022.

What do you like to do in your spare time?

Quite a few hobbies:  hunting, fishing, exercise, reading, shooting replica firearms from the 1800’s, boating, traveling (more now that I’m not tied down by the academic calendar!), snowmobiling, snowshoeing, moving snow in the winter, and hiking. Never a dull moment. We have two lovable dogs, Fritz and Penne.

Dr. Bohmann, what is your advice for new students? 

“It is important to study hard, but also important to play hard. If you are going to come to Michigan Tech you need to embrace the outdoors, because it’s here.”

Hometown?

Cincinnati, Ohio. “I went to college in Dayton, and graduate school in Madison. I just kept moving north until I ran into water—Lake Superior—and then I stopped.”

Family?

Janeen and Nick. Before that, I grew up in a family of 10.

What do you like to do in your spare time?

I like to snowshoe to and from work.

What is the most rewarding aspect of your job?

“Realizing that I am impacting students all across the college. Although I am more removed from day to day interactions, I have a chance to make sure they are getting a great education.”

SWE Hosts Evening with Industry in 2022

Event room with tables and presentation screen.

On September 20 the Society of Women Engineers (SWE) hosted its annual Evening with Industry (EWI). The event brought together over 115 students and sponsors from 23 companies. The highlight of the evening was keynote speaker Carrie Struss from Milwaukee Tool, who discussed career development and tips from her career journey.

The section would like to thank all who attended and participated in making the evening a success. “EWI has been held for 34 years. Its success is due to the involvement and commitment of the SWE Section and our EWI Committee,” said Gretchen Hein, the section’s advisor.

The EWI Committee comprised four students: Alli Hummel (civil engineering), Natalie Hodge (electrical and computer engineering), and Maci Dostaler and Kathleen Heusser (biomedical engineering).

The SWE section works closely with Career Services to ensure the sponsor registration and support runs smoothly. The section thanks the sponsors for their support and input. They are truly part of the Michigan Tech learning community. These corporate representatives visit with the students during EWI and guide the students through the transition from student to professional. These interactions greatly help students learn how to advocate for themselves and others as they begin their careers.

Many students commented about the benefits of EWI:

  • “I got to know the recruiters before Career Fair and was able to get an interview.”
  • “I talked with Gerdau after EWI and they pulled me aside, went through my resume, and did a mini interview!”
  • “The Textron recruiter I talked to was very excited about me coming to the Textron booth at Career Fair. I’m definitely applying to a company (CWC Textron) I hadn’t considered before today!”
  • “Last year, I stepped into a one-on-one meeting with Stellantis on a whim which led to a successful internship with them, changing my whole career direction!”

SWE has begun planning the 2023 EWI event. If you are interested in learning more about it, please contact us at SWEEWI@mtu.edu.

Paul van Susante: Multiplanetary INnovation Enterprise (MINE)

Dr. Paul van Susante’s Planetary Surface Technology Development Lab (PSTDL) at Michigan Tech, home of the Dusty Thermal Vacuum Chamber. It’s about as close to moon conditions as one can get on Earth!

Paul van Susante shares his knowledge on Husky Bites, a free, interactive webinar this Monday, 10/3 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.

Paul van Susante

What are you doing for supper this Monday night 10/3 at 6 pm ET? Grab a bite with Dean Janet Callahan and Paul van Susante, Assistant Professor, Mechanical Engineering—Engineering Mechanics at Michigan Tech. Joining in will be several of his current Michigan Tech students, all members of MINE, the Multiplanetary INnovation Enterprise: electrical engineering majors Brenda Wilson and Gabe Allis; and mechanical engineering major Parker Bradshaw.

Wilson, Allis and Bradshaw—along with about 50 other student members of the MINE team—design, test, and implement robotic technologies for extracting (and using) local resources in extreme environments. That includes Lunar and Martian surfaces, and flooded subterranean environments here on Earth. Prof. van Susante helped launch the team, and serves as MINE’s faculty advisor.

The award-winning Enterprise Program at Michigan Tech involves students—of any major—working in teams on real projects, with real clients. Michigan Tech currently has 23 different Enterprise teams on campus, working to pioneer solutions, invent products, and provide services.

“As an engineer, I’m an optimist. We can invent things that allow us to do things that now seem impossible.”

Paul van Susante
Students in the Huskyworks Lab at Michigan Tech work on the T-REX rover (Tethered permanently-shadowed Region Explorer). The T-REX lays down lightweight, superconducting cable connected to a lander, and it won NASA’s top prize—the Artemis Award.

MINE team members build and test robotic vehicles and technologies for clients in government and the private sector. They tackle construction and materials characterization, too. It all happens in van Susante’s Planetary Surface Technology Development Lab (PSTDL) at Michigan Tech, a place where science fiction becomes reality via prototyping, building, testing—and increasing the technology readiness and level of tech being developed for NASA missions. The PSTDL is also known as Huskyworks.

Prior to coming to Michigan Tech, Prof. van Susante earned his PhD and taught at the Colorado School of Mines, and also served as a NASA Faculty Fellow. He has been involved in research projects collaborating with Lockheed Martin, Northrop Grumman, SpaceX, TransAstra, DARPA, NASA Kennedy Space Center, JPL, Bechtel, Caterpillar, and many others.

Prof. van Susante created the PSTDL’s Dusty Thermal Vacuum Chamber himself, using his new faculty startup funding. It’s a vacuum-sealed room, partially filled with a simulated lunar dust that can be cooled to minus 196 degrees Celsius and heated to 150 degrees Celsius—essentially, a simulated moon environment. In the chamber, researchers can test surface exploration systems (i.e., rovers) in a box containing up to 3,000 pounds of regolith simulant. It’s about as close to moon conditions as one can get on Earth.

Students in the PSTDL move a testbox into position for testing in the Dusty Thermal Vacuum Chamber.

The NASA Artemis program aims to send astronauts back to the moon by 2025 and establish a permanent human presence. Building the necessary infrastructure to complete this task potentially requires an abundance of resources because of the high cost of launching supplies from Earth. 

“An unavoidable obstacle of space travel is what NASA calls the ‘Space Gear Ratio’, where in order to send one package into space, you need nearly 450 times that package’s mass in expensive rocket fuel to send it into space,” notes van Susante. “In order to establish a long-term presence on other planets and moons, we need to be able to effectively acquire the resources around us, known as in-situ-resource utilization, or ISRU.”

“NASA has several inter-university competitions that align with their goals for their up-and-coming Artemis Missions,” adds van Susante. 

Huskyworks and MINE have numerous Artemis irons in the fire, plus other research projects, too. We’ll learn a lot more about them during Husky Bites.

LUNABOTICS

Electrical engineering undergraduate student Brenda Wilson serves as the hardware sub-team lead of the Astro-Huskies, a group of 25 students within MINE who work on an autonomous mining rover as part of NASA’s Lunabotics competition. It’s held every year in Florida at the Kennedy Space Center with 50 teams in attendance from universities across the nation. This is the Astro-Huskies’ third year participating in the competition, coming up in May 2023. 

This year the Astro-Huskies are designing, building, testing, and competing with an autonomous excavation rover. The rover must traverse around obstacles such as mounds, craters, rocks; excavate ice to be used for the production of rocket fuel, then return to the collection point. By demonstrating their rover, each team in the competition contributes ideas to NASA’s future missions to operate on and start producing consumables on the lunar surface. 

DIVER

Mechanical engineering undergraduate student Gabe Allis is manager of the MINE team’s DIVER project (Deep Investigation Vehicle for Energy Resources). The team is focused on building an untethered ROV capable of descending down into the Quincy mine to map the flooded tunnels and collect water samples. The team supports ongoing research at Michigan Tech that aims to convert flooded mine shafts into giant batteries, or Pumped Underground Storage for Hydropower (PUSH) facilities.

“Before a mine can be converted into a PUSH facility it must be inspected, and most mines are far deeper than can be explored by a conventional diver,”Allis explains.

“This is where we come in, with a robust, deep-diving robot that’s designed for an environment more unforgiving than the expanse of outer space, and that includes enormous external pressure, no communication, and no recovery if something goes wrong,” he says.  

“Differences in water temperature at different depths cause currents that can pull our robot in changing directions,” adds Allis. “No GPS means that our robot may have to localize from its environment, which means more computing power, and more space, weight, energy consumption, and cooling requirements. These are the sort of problems that our team needs to tackle.”

TRENCHER

During Husky Bites, Bradshaw will tell us about the team’s Trencher project, which aims to provide proof-of-concept for extracting the lunar surface using a bucket ladder-style excavator. “Bucket ladders offer a continuous method of excavation that can transport a large amount of material with minimal electricity, an important consideration for operations on the moon,” Bradshaw says. “With bucket ladders NASA will be able to extract icy regolith to create rocket fuel on the moon and have a reliable method to shape the lunar surface.” Unlike soil, regolith is inorganic material that has weathered away from the bedrock or rock layer beneath.

Parker Bradshaw, also a mechanical engineering student, is both a member of MINE and member of van Susante’s lab, where he works as an undergraduate researcher. “Dr. van Susante is my boss, PI, and Enterprise advisor. I first worked with him on a MINE project last year, then got hired by his lab (the PSTDL) to do research over the summer.”

Bradshaw is preparing a research paper detailing data the team has gathered while excavating in the lab’s Dusty Thermal Vacuum Chamber, with a goal of sharing what was learned by publishing their results in an academic journal.

The PSTDL’s field-rover HOPLITE gets ready for field-test last winter.

“An unavoidable obstacle of space travel is what NASA calls the ‘Space Gear Ratio’, where in order to send one package into orbit around Earth, you need nearly 10 times that package’s mass in expensive rocket fuel to send it into space, and even more for further destinations,” van Susante explains. “So in order to establish a long-term presence on other planets and moons, we need to be able to effectively acquire the resources around us, known as in-situ-resource utilization, or ISRU.”

In the world-class Huskyworks lab (and in the field) van Susante and his team work on a wide variety of projects:

Paul van Susante served as a mining judge during the 2018 Regolith Mining Competition at the NASA Kennedy Space Center Visitor Center

NASA Lunar Surface Technology Research (LuSTR)—a “Percussive Hot Cone Penetrometer and Ground Penetrating Radar for Geotechnical and Volatiles Mapping.”

NASA Breakthrough Innovative and Game Changing (BIG) Idea Challenge 2020—a “Tethered permanently shaded Region EXplorer (T-REX)” delivers power and communication into a PSR, (also known as a Polarimetric Scanning Radiometer).

NASA Watts on the Moon Centennial Challenge—providing power to a water extraction plant PSR located 3 kilometers from the power plant. Michigan Tech is one of seven teams that advanced to Phase 2, Level 2 of the challenge.

NASA ESI Early Stage Innovation—obtaining water from rock gypsum on Mars.

NASA Break the Ice—the latest centennial challenge from NASA, to develop technologies aiding in the sustained presence on the Moon.

NASA NextSTEP BAA ISRU, track 3—”RedWater: Extraction of Water from Mars’ Ice Deposits” (subcontract from principal investigator Honeybee Robotics).

NASA GCD MRE—Providing a regolith feeder and transportation system for the MRE reactor

HOPLITE—a modular robotic system that enables the field testing of ISRU technologies.

Dr. van Susante met his wife, Kate, in Colorado.

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

Helping people and making the world a better place with technology and the dream of space exploration. My interest came from sci-fi books and movies and seeing what people can accomplish when they work together.

Hometown and Hobbies?

I grew up in The Netherlands and got my MS in Civil Engineering from TU-Delft before coming to the USA to continue grad school. I met my wife in Colorado and have one 8 year old son. The rest of my family is still in The Netherlands. Now I live in Houghton, Michigan, not too far from campus. I love downhill and x-country skiing, reading (mostly sci-fi/fantasy), computer and board games, and photography.

Dr. van Susante has been a huge help—not just with the technical work, but with the project management side of things. We’ve found it to be one of the biggest hurdles to overcome as a team this past year.

Brenda Wilson

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

My dad, who is a packaging engineer, would explain to me how different machines work and how different things are made. My interest in electrical engineering began with the realization that power is the backbone to today’s society. Nearly everything we use runs on electricity. I wanted to be able to understand the large complex system that we depend so heavily upon. Also, because I have a passion for the great outdoors, I want to take my degree in a direction where I can help push the power industry towards green energy and more efficient systems.

Hometown, family?

My hometown is Naperville, Illinois. I have one younger brother starting his first year at Illinois State in general business. My Dad is a retired packaging engineer with a degree from Michigan State, and my mom is an accountant with a masters degree from the University of Chicago.

Any hobbies? Pets? What do you like to do in your spare time?

I am an extremely active person and try to spend as much time as I can outside camping and on the trails. I also spend a good chunk of my time running along the portage waterfront, swing dancing, and just recently picked up mountain biking.

I got involved in the DIVER project in MINE, and have enjoyed working with Dr. van Susante. He’s a no nonsense kind of guy. He tells you what you need to improve on, and then helps you get there.

Gabe Allis
Gabe Allis

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

I first became interested in engineering when my great-uncle gave me a college text-book of his on engineering: Electric Circuits and Machines, by Eugene Lister. I must have been at most 13. To my own surprise, I began reading it and found it interesting. Ever since then I’ve been looking for ways to learn more.

Hometown, family?

I’m from Ann Arbor, Michigan, the oldest of nine. First in my family to go to Tech, and probably not the last. 

Any hobbies? Pets? What do you like to do in your spare time?

I like to play guitar, read fiction, mountain bike, explore nature, and hang out/worship at St. Albert the Great Catholic Church.

“Doing both Enterprise work and research under Dr. van Susante has been a very valuable experience. I expect to continue working in his orbit through the rest of my undergrad degree.”

Parker Bradshaw
Parker Bradshaw

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

I was first introduced to engineering by my dad, who manufactured scientific equipment for the University of Michigan Psychology department. Hanging around in his machine shop at a young age made me really want to work with my hands. What I do as a member of MINE is actually very similar to what my dad did at the U of M. I create research equipment that we use to obtain the data we need for our research, just for me it’s space applications (instead of rodent brains).

Hometown, family?

I grew up in Ann Arbor Michigan, and both of my parents work for the University of Michigan Psychology department. My dad is now retired.

Any hobbies? Pets? What do you like to do in your spare time?

I have a variety of things to keep me busy when school isn’t too overbearing. I go to the Copper Country Community Art Center Clay Co-Op as often as I can to throw pottery on the wheel. I also enjoy watercolor painting animals in a scientific illustration style. Over the summer I was working on my V22 style RC plane project.

SWE, Aerospace Enterprise Represent MTU at Women in Aviation Day

Women in Aviation Day banner with image of Amelia Earhart.

On September 17, 2022, eight students from the Aerospace Enterprise and Society of Women Engineers represented Michigan Tech at the first annual Women in Aviation Day in Wausau, Wisconsin.

Participating students were:

From Aerospace: Heather Goetz, Seth Quayle and Nolan Pickett (mechanical engineering); and Zoe Knoper (cybersecurity).

From SWE: Sophie Stewart and Katherine Rauscher (mechanical engineering); Kathryn Krieger (environmental engineering); and Cailyn Koerber (engineering management).

This event was hosted by the Learn Build Fly organization, which does incredible volunteer work in engaging their community in aviation. As summarized by Wausau’s WSAW-TV News Channel 7, “The event aimed to get more women involved in recreational and professional aviation. Children had the chance to participate in ‘Young Eagle Flights’ by going for airplane rides, while other aviation organizations gave information about their programs.”

Visitors to the event had the opportunity to see a 3D model of the newest Aerospace Enterprise satellite design and learn how these students were designing and building satellites to go into space, while the SWE team worked with visitors on an outreach activity, Paper Circuits.

Participants’ comments included:

Nolan Pickett: “Our Enterprise was given the opportunity to not only celebrate the women in our program, but also promote STEM to the next generation of college students — and fly in a WWII era B-25!”

Kathryn Krieger: “I loved being able to see so many young girls getting excited about STEM. It was really inspiring to see the many ways kids are getting involved with aviation and other STEM disciplines from such a young age.”

Both SWE and the Aerospace Enterprise teams enjoyed volunteering at Women in Aviation, learning more about the history of aviation and meeting with folks interested in aviation careers. This was a unique outreach opportunity and they appreciated the support they received from Admissions and the College of Engineering.

Beyond Measure: Nucor Metrology Center at MTU Hosts Donor Appreciation Event

“We want to see our students use their hands for physical engineering, and that happens in measurement,” said Rachel Store, Michigan Tech research engineer and head of the Nucor Metrology Center. The new center is located on campus in the RL Smith Building. Photo credit: Matt Monte

09/20/2022

Michigan Technological University’s Department of Mechanical Engineering-Engineering Mechanics (ME-EM) officially opened the Nucor Metrology Center on Tuesday, Sept. 20, with a donor appreciation event recognizing Nucor Corporation for its generous support of the Center.

University and department officials also recognized Milwaukee Tool and Nexteer for their equipment donations to the Center.

“We thank Nucor for their very generous donation of $100,000 to establish the Nucor Metrology Center in the ME-EM department here at MTU,” said Jason Blough, interim department chair. “We would also like to thank Milwaukee Tool, Nexteer and Richard Crosby for their assistance in enhancing the capabilities of the facility. Industry support has always allowed us to offer outstanding experiences to our students and to grow our research portfolio and capacity in ways that would not otherwise be possible.”

“Huskies are ready to tackle the next problem and help create the future with innovative solutions.”

Kate Amar-Fox, melt shop metallurgist, Nucor

“Nucor is excited to be a part of expanding the on-hand and lab experiences with the funds for the metrology lab,” said Kate Amar-Fox, melt shop metallurgist at Nucor. “We believe that powerful partnerships create powerful results and are looking forward to these partnerships for years to come.”

The Nucor Metrology Center provides students with the resources to make highly accurate measurements for their project components, advancing the Michigan Tech College of Engineering’s objective to provide world-class undergraduate and graduate education to support a diverse workforce and societal needs. 

“We want to see our students use their hands for physical engineering, and that happens in measurement,” said Rachel Store, Michigan Tech research engineer and head of the Nucor Metrology Center. “The students will take data to document their product performance, all while better understanding their product quality through metrics.”

The lab features both traditional and leading-edge, industry-standard equipment, including calipers, micrometers, a flexible arm coordinate-measurement machine (CMM), optical microscope, microhardness testers, tachometers, strobometers, and infrared and thermal scanners.

“Nucor’s donation allowed us to purchase a Leica DVM6 motorized digital microscope and a Hexagon Metrology absolute measurement arm, giving us the ability to do high-quality metrology measurements for part inspection,” said Blough. “We are already using this technology in one of our research programs and in one of our undergraduate courses.”

Store says the Center gives students exposure to the equipment they will see in industry when they graduate. “We know familiarity and fluency strengthen their hands-on, intensive experience,” she said. “Confidence is built on reality.”

Pasi Lautala: Railroads—Back to the Future

The US rail network comprises nearly 140,000 miles of track—and more than 200,000 highway-rail grade crossings. Photo credit: Eric Peterson.

Pasi Lautala shares his knowledge on Husky Bites, a free, interactive webinar this Monday, 9/26 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.

Dr. Pasi Lautala

What are you doing for supper this Monday night 9/26 at 6 ET? Grab a bite with Dean Janet Callahan and Pasi Lautala, associate professor of Civil, Environmental, and Geospatial Engineering at Michigan Tech.

Lautala directs Michigan Tech’s innovative Rail Transportation Program (RTP), preparing students to thrive and succeed in the rail industry—something he has done for the past 15 years.

Joining in will be Michigan Tech alumnus Eric Peterson, retired assistant chief engineer of public projects at CSX Transportation, who helped establish and grow the RTP at Michigan Tech.

During Husky Bites the two will share the secrets behind the energy efficiency of rail, and guide us from past railroads to what they are today. They’ll also discuss how railroads are securing a future in the era of rapid technology development. 

“Rail is considered more energy efficient. In many ways it is a more sustainable transportation mode compared to highway and air transport, says Lautala. “However, in order for rail transportation to keep up with the other modes of transportation, it must keep developing alongside them—and with an equal amount of passion. In the US, some of those challenges (but also opportunities) include long asset lives, non-flexible structures, and private ownership.”

Pat and Eric Peterson

Before moving to the US from Finland, Lautala worked for several summers with the Finnish Railway system. After graduating from Michigan Tech with his MS in Civil Engineering, he worked for five years as a railroad and highway engineering consultant in Chicago, before returning to Michigan Tech for his PhD in Rail Transportation and Engineering Education.

Michigan Tech’s Railroad Engineering Activity Club, aka REAC, is “for students interested in establishing contacts with, learning about, getting involved with, and a hair’s breadth away from being obsessed with the railroad and transportation industries in the United States of America and beyond.” Lautala and Peterson are honorary members.

“I first met Eric as a young consultant,” Lautala recalls. “He was one of the managers for our client, CSX Transportation. Once I returned to campus as a doctoral student, I learned Eric was a former classmate of my PhD advisor. Eric became an influential force and tireless supporter of our efforts to start the Rail Transportation Program. He still teaches some signals and communications lectures for us.”

“My wife, Pat, and I supported the startup of the Michigan Tech Rail Transportation Program with Pasi as the leader,” adds Peterson. “At the time, we were hiring engineers at CSX for all types of jobs, including field supervisors—people comfortable working both in the field and in the office. The rest of the rail industry was hiring, too.” 

“The railroad industry is still hungry for young people with interest and education in rail transportation,” says Lautala. When he first came to Michigan Tech from Finland in 1996 to earn an MS in Civil Engineering, Lautala brought the railroad bug with him. The son of a locomotive engineer, Lautala grew up in a culture that embraced rail transportation as a sustainable public transit alternative, as well as an efficient way to move freight.

While the US has the most extensive and efficient freight rail system in the world, the development of railroads had been on the back burner for decades, while the rest of the world kept moving forward, he observes. 

In 2007 Lautala established the RTP at Michigan Tech in order to advance rail education to a wide range of students, with integrated coursework, for both undergraduate and graduate students, and a minor in rail transportation. CN, Canadian National Railway Company, quickly came on board as a major sponsor of the program. The RTP also collaborates closely with many industry companies, associations and alumni. Their involvement provides professional networking, education, field trips, conferences, and guest speakers for Michigan Tech students involved in the Railroad Engineering and Activities Club (REAC), the first student chapter ever established by the American Railway Engineering and Maintenance of Way Association (AREMA).

“Students can also take part in hands-on rail industry-sponsored research projects across disciplines. Some topic areas include grade crossing and trespasser safety, materials research on railway equipment, locomotive emissions, the impact of climate change on railroads, and more,” says Lautala. Learning by doing is a central component of RTP’s approach to rail education.

Rail companies actively work with RTP to fill openings with Michigan Tech RTP students, whether for for full time jobs, internships or co-ops. And the RTP Experience wouldn’t be complete without the Railroad Night, an over 15 year tradition at Michigan Tech.

“Rail just makes sense, and it’s something this country needs.”

Lautala initially founded RTP’s innovative Summer in Finland program, which integrated an international component to rail education. It was an intensive five-week program, a collaboration among Michigan Tech, the Tampere University of Technology, and the North American and Finnish railroad industry. “That program created sufficient interest from the students and industry to officially launch the Rail Transportation Program,” Lautala says.

Outside Michigan Tech, Lautala serves as chair of National Academies’ Research Transportation Board Rail Group. “There are so many research possibilities—everything from infrastructure, with automated track-monitoring systems and recycled materials in railroad ties, to energy efficient equipment and operations,” he says.

Team Lautala!

Lautala’s own engineering research currently involves connected and autonomous vehicle communications at grade crossings, with fellow Civil, Environmental, and Geospatial Associate Professor Kuilin Zhang. The two are working to develop safe and efficient driving and routing strategies for autonomous vehicles at railroad grade crossings. Reduced energy consumption, emissions, and potential time delays are some of their goals. Their research is supported with two separate grants from the Federal Railroad Administration (FRA).

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

Prof. Lautala likes to fish, hunt, and play the accordian.

Probably my early summer internships, first at a rail construction site, and then with Finnish Railways.

Hometown?

Kangasala, Finland. I have split my life evenly between Finland and the US, twenty-five years each. I recently spent a year in Finland with my wife and two rascals (children): Olavi (10) and Ansel (8).

What do you like to do in your spare time?

Hobbies, you name it…..soccer (including coaching), hockey, golf, and many other sports. Three accordions and an equal number of bands. I’ve done some acting, too (though that’s been pretty quiet recently).

A rail adventure!

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

I saw the Mackinac Bridge while it was under construction. A few years later when our subdivision was expanded, I spent the summer watching the grading contractor.  

Boating is another hobby. We have a 17’ boat for water skiing and a 20’ sailboat we use each summer for a few weeks on Crystal Lake near Frankfort, Michigan, when our family vacations together.

One of your most memorable accomplishments?

Training as a locomotive engineer.

Hometown?

I was born in Detroit and moved to Bloomfield Township when I was in the 4th grade. I am an only child. I married Patricia Paoli in 1970.

Eric and Pat thus far have three married adult children, and nine grandchildren.

What do you like to do in your spare time

My dad exposed me to both model railroading and real railroads. My primary hobby is model railroading in O Scale 2 rail, which is 1/48 scale. My work was all in the railroad industry.
