Lift Bridge Wins Award, Snags Trailer⁠—Built to Last

Published July 1, 2019

News

Portage Lake Lift Bridge is a double-deck, vertical lift bridge, the only one of its type in Michigan. Here shown with a blue sky and summer day in the background. — The monumental Portage Lake Lift Bridge—a double-deck, vertical lift bridge—is the only one of its type in Michigan.

The Portage Lake Bridge, or more commonly known as the Lift Bridge, was designated in May, 2019 as an American Society of Civil Engineers (ASCE) Michigan State Historic Civil Engineering Landmark of the Year. Built in 1959, the bridge provides a key role in connecting the Keweenaw’s local industries to the nation, and uses a first-of-its-kind intermediate lift span position. It also was an early example of accelerated bridge construction.

The Lift Bridge is a double-deck vertical lift bridge⁠—the only one of its type in Michigan and uncommon nationwide. While the lower deck was originally used by trains; these days, snowmobiles roar through the lower deck in winter. This riveted steel bridge was built to support the Keweenaw’s copper mining and logging industries and to serve the nation’s need for copper and timber. So you might say, it’s built to carry heavy loads!

I was invited one recent Friday to meet one of our civil engineering alumni from the class of ‘66, Donald R. Anderson. He was docked in Hancock, just east of the Lift Bridge, traveling with his son, up from Grand Haven. They were in town waiting for the extended family, to arrive and spend a few weeks together on the boat as they worked their way through the Apostle Islands area. We were chatting, taking a look at the engines, and enjoying some local cider when BAM! A very loud boom sounded from the Lift Bridge. We all turned to watch as a tandem trailer loaded with trailers pulled to a halt. Over the next hour, inspections of the rig, and bridge seemed to happen while we looked up from below with high-tech binoculars and speculated about the impact. We figured that being in tandem, one of the trailers rocked up just as the truck pulled through and snagged that edge a bit. The truck eventually pulled down and around and took time to do a safety check just behind the marina.

On my way home, pedaling across the bridge I stopped and took a few images. You can see how there is a bit of battered metal at the leading edge on the Houghton side. No easy way to tell what marks are new or old from down on the ground (and I am a metallurgist). My assessment⁠—that bridge was built to last. I bet it will still be in use for its 100th anniversary. They build things to last up here in the Keweenaw. And remember your metallurgy: steel can plastically deform and even strengthen as a result of the increased number of dislocations.

Dr. Tess Ahlborn, professor of Civil and Environmental Engineering at Michigan Technological University, working with two recent civil engineering masters of science graduates Emma Beachy and Michael Prast, submitted the application of Lift Bridge for Historic Civil Engineering Landmark Award at both the state and national levels. While Lift Bridge has now won the state ASCE Landmark of the Year award, the jury’s still out on the national level award. You can read more about the Lift Bridge here.

Julie (Varichak) Marinucci earned her Bachelor of Science in Mining Engineering at Michigan Tech in 2002. She is now Mineral Development Specialist at St. Louis County Land and Minerals Department in Hibbing, Minnesota.

After a 15-year break, Mining Engineering officially returns to Michigan Tech, with BS, MS, and PhD degree programs and cutting-edge research. Learn more online.

Julie Marinucci earned her Bachelor of Science in Mining Engineering from Michigan Tech in 2002. She knew early on that mining would enable her to work globally, but also return home someday to northern Minnesota and have a good career there, too. Turns out, she was right.

What fostered your own path to studying and working in mining?
Mining Engineering kind of landed in my lap. I knew I wanted to be an engineer of some type and that I wanted to work outdoors. Civil Engineering seemed like the most likely choice, but then I met Murray Gillis, a mining engineering instructor at Michigan Tech. Murray was at a local college fair and he sparked my curiosity, not just in Michigan Tech, but also in Mining Engineering. My campus visit, and spending the summer after high school working in a mine, sealed the deal!

Describe some challenges that you face in your work.
The biggest challenge is the general misunderstanding of the mining industry. Many people do not understand the amount of care that goes into extracting minerals for the conveniences and protections we as a society have come to expect. Mining considers the full lifecycle of the land, careful consideration of the environmental conditions prior to mining, efficient extraction of the minerals of interest, and thoughtful reclamation with the next generation of land use in mind. I have always thought a big part of my job is to ensure the general public understands the efforts taken in developing a mine.

What has changed the most in mining engineering over the course of your career?
The continuous evolution of technology in mine planning has been fun to watch. Operations are now utilizing drone technology and laser scanning to manage pit operations, blast efficiency, ore grading, and more. I had the opportunity to work with engineers early in my career who had the large map tables and boxes of colored pencils. Fast forward now to laser scanners, drones, remote equipment monitoring, and more!

What changes do you expect to see in the future of mining?
I expect to see the way we work in mining to evolve, and look to more flexible work arrangements that will bring in a more diverse workforce. The days where you must be at your 1950’s steel desk working from 6 am to 6 pm will evolve into the ability to work remotely. It will allow for a different type of operational accessibility while providing for better balance in life.

What is your most surprising experience as a mining engineer to date?
When I started down the journey to become a mining engineer, I envisioned working my way through an operation in a very technical role. Through the years, I found that my degree has allowed me to reinvent myself many times over.

I started my career with Caterpillar in a marketing position. It was completely unexpected, but Cat was looking for someone who could understand the equipment, understand the mining industry, and effectively communicate with clients. What a great job! I went on to enjoy many roles at Cleveland Cliffs iron mining operations, where I learned to be an engineer, manage operation crews in the pit, and had the great learning experience of working at a greenfield operation in Canada (with a language barrier!). When I decided to leave Cliffs, I discovered the contacts I had made, along with understanding of mining operations, positioned me well for a career in consulting. My time with Short Elliott Hendrickson Inc. working in business development for mining and heavy industry taught me how to assemble a team to help solve problem and deliver a successful project. Then came my current role, with St. Louis County—a brand new position created to ensure that the vast mineral wealth held within the county was protected. The chance to define the job and lay out the mining and mineral strategy for the county was too good to pass up. St. Louis County holds world class iron, copper and nickel deposits, to name a few, and has a long mining history of over 130 years. As Mineral Development Specialist, I work closely with the Minnesota Department of Natural Resources, and local mining and exploration companies and communities, to ensure we are responsibly moving mining forward for the benefit of the region and the Tax Forfeited Land Trust.

Why do you think it was important to reinstate the mining engineering degree program at Michigan Tech?
Michigan Tech was founded as a mining engineering school and the demand that was created in 1858 still holds true today. Michigan Tech is positioned strategically near two large mining districts with growing interest in mineral development. The need for qualified mining professionals to move these project forward is great. The alumni network is willing to support these students through their education to ensure they have the best start possible.

Why should a student enter the field of mining engineering now?
The need for skilled mining engineers that love our region and want to stay, work and raise a family is strong, while the nationwide and global demand continues to grow. Mining in not for the faint of heart, but if you can weather the storm it’s a fulfilling career with many ways to leverage a mining engineering degree.

What are the greatest rewards and challenges mining engineers face now, and will face in the future?
Mining engineers should be proud to know that they are part of the fabric that maintains our quality of life, helps to grow our food, provides the materials for our ever-expanding tech advances, and keeps our families safe. This role in our modern life is not well-understood, but it’s a very important role. The future has great potential to continue to move our industry into next levels of efficiency, safe production, beneficial reuse of waste streams—and maybe mining the moon! The stars are the limit!

What’s next in your career?
I look forward to continuing to explore the opportunity to manage the land for mineral development, while planning for beneficial reuse of the land and the residuals. The ability to make an impact in my backyard is exciting and I look forward to evolving the role and myself over the years.

In his guest blog, Michigan Tech electrical engineering alumnus Charles L. Hand ’62 tells the story of his journey around the largest freshwater lake, by surface area, in the world.

Chuck Hand stands at the waterfront on a low bluff — The author, Chuck Hand ’62

On September 10, 2018, via private automobile, I completed circumnavigating Lake Superior. It only took fifty-six years, a fascinating journey of over 1,300 miles. I made this adventure over five decades, in several cars, at numerous times, and with diverse friends and relatives. Come join me exploring this fascinating body of water.

The attraction of the immense Great Lakes is irresistible. During the first eighteen years of my life, I lived within thirty miles of Lake Erie in Tecumseh, in the southeastern corner of the Lower Peninsula of Michigan. Having a picnic on its shores and swimming in its crystal-clear cool waters was always a treat.

For the next fifteen years, I lived and worked within a mile of the shores, first of Lake Superior, then Lake Michigan. Witnessing gigantic freighters, called “lakers”, transporting their precious cargoes of iron ore, coal, and grain from Duluth at the western tip of Lake Superior to markets in eastern United States and the rest of the world, intrigued me. Riding the ferry carrying railroad cars, automobiles, and other passengers on a four-hour journey across Lake Michigan was a unique pleasure.

As a young lad, my first exposure to Lake Superior was with my parents while on vacation from our home in southeastern Michigan. We traveled across the Straits of Mackinac via car ferry to the Upper Peninsula cities of Sault Saint Marie, Marquette, Houghton, and Copper Harbor. Little did I know this initial excursion would lure me back again and again to the largest surface area freshwater lake in the world.

In my senior year of high school, I answered a Michigan College of Mining and Technology (now Michigan Technological University) recruiter’s invitation. He convinced me to spend the next four years of my life at the snow-blanketed engineering monastery in Houghton. Not only was I studying and learning a profession, but was experiencing the Scandinavian heritage of the Keweenaw Peninsula, the death knell of the booming copper mining era, and the lake’s climatic effect as it creates gigantic snow packs.

After graduation in 1962, my chosen profession took me physically, although never emotionally, away from Lake Superior to Milwaukee, Chicago, and finally Southern California. I never forgot my college years in Houghton. Several times I returned to visit my alma mater, sometimes stopping at Pictured Rocks National Lakeshore, Agawa Canyon in Ontario, or witnessing the great bulk cargo lakers ply their way through the Soo Locks in the St. Mary’s River. The best way to view this mighty parade of ships is first hand, cruising the St. Mary’s River on the deck of an excursion boat being raised and lowered twenty-one feet between Lake Huron and Lake Superior. Since 1957, the Straits of Mackinac could be crossed on one of the longest suspension bridges in the world.

Asking to identify my favorite spot is like asking which of my children I love the most, but I will try.

In 1997, while living in Southern California, an opportunity to complete another portion of the circumnavigation adventure occurred. I was selected as a member the staff of the Ninth Canadian National Jamboree, hosted by Scouts Canada. It was scheduled for Thunder Bay, Ontario, but where was Thunder Bay? After some research, I discovered that the city was 100 miles, by water, directly north of Houghton. During the early 1960s it had been two cities, Fort William and Port Arthur, the largest grain shipping ports in the world at that time. With fellow scouting friends, I flew to Minneapolis then carpooled to the Jamboree along the spectacular scenic northwest shore of the lake, by way of Duluth and Grand Portage. My task was to introduce the Scouts to the wonders of the Great Lakes and its commerce. Part of the introduction was boarding a docked laker. After the Jamboree, we ventured eastbound through the forested solitude of the lake’s far north shore, driving through Nipigon and Wawa to the the lake’s eastern tip. Upon reaching Sault Saint Marie, a second major portion of the circumnavigation was complete.

The leg of the circumnavigation adventure between Duluth and Houghton still needed to be completed. During the summer of 2008, my beautiful wife Doris, a native of Milwaukee, and I decided to vacation in areas of northern Minnesota, Wisconsin, and Michigan that neither she nor I had ever visited. Again, we flew into Minneapolis, rented a car, and headed north. From Duluth at the western tip of Lake Superior with its international harbor, we turned east. After a stop to explore the archipelago called Apostle Islands National Lakeshore, my circumnavigation, upon reaching Houghton, was complete.

Asking to identify my favorite spot is like asking which of my children I love the most, but I will try. There is Houghton and Michigan Technological University, where four years of my life was spent launching a successful career in electrical power engineering. There is Sault Saint Marie and the gigantic Great Lake freighters carrying their cargos to the industrial centers of the United States and the world. There is Nipigon where the imaginary miniature toy canoe in the book, Paddle-to-the-Sea, started its epic journey through all five of the Great Lakes and on into the Saint Lawrence, crossing the Atlantic, culminating its journey along the shores of France. There is Wawa and their memorable, huge Canadian goose guarding the entrance to the city. For scenic beauty, both the north shore and the south shore are exquisitely picturesque, each in their own way.

But, Michigan Technological University (MTU) in Houghton has to be my favorite spot since it had a major positive influence on my entire life. Someday, I hope to return to Lake Superior and complete a second circumnavigation, although this second trek will probably be completed in slightly less time.

Professor Martin Auer honored with Lifetime Achievement Award

Dr. Martin Auer, Michigan Tech Civil and Environmental Engineering Professor Emeritus hold us a test capsule on board a research vessel on Lake Superior — Congratulations to Dr. Martin Auer, Professor of Civil and Environmental Engineering at Michigan Technological University

BROCKPORT, NY — The International Association for Great Lakes Research has honored Civil and Environmental Engineering Professor Emeritus Martin (Marty) Auer with its 2019 Lifetime Achievement Award. Presented at IAGLR’s 62nd Annual Conference on Great Lakes Research, the award recognizes important and continued contributions to the field of Great Lakes research over a period of 20 years or more.

“Someone lights a fire in your belly,” Auer says, when asked to reflect on his career. “You study hard. You demand the best of yourself. You make some friends. You learn some things. One day, the phone rings and a voice says, ‘Watson, come quickly, the game is afoot.’ The lakes are calling. You go. It’s a grand life.”

Auer takes a unique approach to his research, blending field and laboratory work with mathematical modeling. He has made significant contributions to a range of topics, with his research almost always addressing high-priority management concerns. He is best known for his groundbreaking work on Cladophora, a green alga occurring naturally along most Great Lakes shorelines, where it grows submerged in long strands. It becomes a nuisance when it breaks free, clogging water intake pipes and fouling beaches with its decay.

“Marty and his colleagues conducted a beautiful series of experiments and field studies in the early 1980s that led to the development of the Great Lakes Cladophora model,” says Harvey Bootsma, an associate professor at the University of Wisconsin-Milwaukee.

This model has informed our understanding of the connection between phosphorus entering the lakes and the growth of Cladophora, as well as how invasive mussel infestation triggers the alga’s growth. Updated over time, the model continues to guide management decisions about phosphorus in many regions around the Great Lakes.

This ability to bridge the gap between research and the real world is driven by a rare sense of responsibility, according to Val Klump, dean of the School of Freshwater Sciences at the University of Wisconsin-Milwaukee. In recalling Auer’s participation in an early debate on removing phosphorus from the lakes, Klump says, “Here was a guy willing to apply what he knew and understood in the real world in a heart-felt effort to make the lakes better. That takes guts and a sign of duty.”

Auer takes a broad-scale view, making him one of the “best minds in the Great Lakes community,” Klump notes. “This is not a guy who claims to have all the answers, but who will pose some very insightful questions; and it is those questions which have driven much of our science forward.”

Perhaps this bigger-picture view explains why Auer has invested so much effort in supporting young scientists. “I am not sure I know of an environmental engineering professor who works more closely at training and mentoring his students, many of whom have remained in the Great Lakes Basin to continue their work,” notes Joseph DePinto, retired scientist and long-time colleague.

Junior colleagues at Michigan Tech echo this sentiment, citing Auer as a mentor and friend. “He has always tried his best to foster effective research skills…and the development of a productive balance between research, teaching, and service,” notes Pengfei Xue, assistant professor at Michigan Tech.

The depth of Auer’s commitment to the next generation runs even deeper, according to Guy Meadows, director of Michigan Tech’s Great Lakes Research Center. “Through Marty’s never narrowing view of broader impacts, he has remained a tireless champion of K-12 education and outreach.” Through his many outreach activities, which have earned him several awards, Auer has been instrumental in educating thousands of K-12 students about the importance of Great Lake stewardship.”

“I heard Marty talk about the importance of our legacy as individuals who inhabit this patch of our planet for a few short decades and our responsibility to those who follow us,” Klump recalls. “Not what I expected, but it has stuck with me, and inspired me still. I am very grateful for a guy like Marty. We need more like him.”

Keys to a Unique Nameplate

Published June 13, 2019

By callahan

News

I’ve just received an amazing gift. A unique, foundry-casting of my name in brass. The Michigan Technological University foundry is one of the few remaining operational university metallurgical facilities where students can work to create 3D positive prints, stamp them into sand, and then pour (with eye protection, fireproof aprons and face shields, tongs, and gloves) orange-hot molten metal into the sand to create metal castings.

I’m near the end of my first year as Dean of Engineering at Michigan Technological University. As background, it’s relevant to note that Michigan Tech was founded in 1885 to support the emerging copper and iron mining activities Michigan’s western Upper Peninsula. Founded to train the future mining and metallurgical engineers, Michigan Tech through the years has established an incredibly strong reputation for training “can-do” engineers—many who know a bit about metallurgy! But even I was surprised when presented with a personalized nameplate for my office—cast in the MSE foundry using brass recovered from a cache of old university office keys!

The university had accumulated a large number of brass keys from locks that were long-ago decommissioned. Looking for an ultimate way to securely dispose of the keys, the university public safety department approached the foundry team to ask if they could be melted and destroyed using the foundry. “Of course,” they replied. Timing is always important. At about that same time, Materials Science and Engineering Chair Steve Kampe had asked the foundry team to make a nameplate for me. I was just starting my new job as Dean, and happened to have my own credentials as a metallurgical engineer. Over the next several weeks, a pattern was 3D printed and the key brass was compositionally modified to facilitate its use as a casting alloy—and the nameplate came to be.

Sam Dlugoss holds a version of the finished nameplate — Sam Dlugoss

The “Dean nameplate project” was led by Sam Dlugoss, a chemical engineering student hired as a co-op employee in the foundry. I am humbled each time I see it as I unlock my office door with my own brass key. I think about the hands of the graduate students, staff, and faculty that are represented in the keys that ultimately were melted into my nameplate—and how these dedicated and aspiring engineers and scientists carried their keys and opened their labs and offices each day for many years, to do the work that has established the reputation we now carry on at Michigan Tech.

Last week, students in the foundry created more nameplates, this time for our College of Engineering Advisory Board Members. In the photos below, the students are working with iron.

A dip type thermocouple probe is used to measure the temperature of the liquid iron before tapping the furnace.

As the iron is tapped into the ladle, ferrosilicon inoculant is added to the liquid stream. The inoculant provides nucleation sites for creating the proper iron-graphite microstructure in the solidified gray cast iron metal. — As the metal is tapped into the ladle, ferrosilicon inoculant is added to the liquid stream. The inoculant provides nucleation sites for creating the proper iron-graphite microstructure in the solidified gray cast iron metal.

After tapping into the ladle is complete, some sparks fly as the inoculant reacts with the liquid iron.

The pouring basin is kept full so that the molten metal quickly fills the mold cavity.

As the pouring team fills the 3rd mold [middle ground], an MSE staff member [foreground] lifts the mold jacket from the 2nd mold, and will transfer it to the waiting 4th mold [background] prior to it being poured. The jacket supports the green sand mold against the hydraulic pressure of the liquid metal entering the mold.

The metal has solidified but the molds are left to cool for a few minutes before the castings are shaken out.

A mold with a casting inside is transported to the shake-out bin.

The molds are dumped into the shake-out bin where they disintegrate. Because sand is a good insulator the castings are still very hot after shake-out, as evidenced by the still glowing runner section. A few taps with a hammer loosens the sand. This green sand will be reused to make more molds after it is conditioned and remixed with water.

Once cool, the nameplates will be separated, then buffed and polished.

Now, if you’re interested in metallurgy, and you want to know more, please let me know—Callahan@mtu.edu.

John Gierke (GMES/EPSSI) is Principal Investigator on a project that has received a $582,752 grant from the National Science Foundation. This is a potential three-year project.

Luke Bowman (GMES), Alex Mayer (CEE), Fengjing Liu (Forestry), and Angie Carter (SS) are Co-PI’s on the project titled “IRES Track III: Collaborative Research: Coupling Participatory and Hydrological Research for Adapting to Extreme Hydrometeorological Events in Agricultural Communities, El Salvador.”

Extract

In this project, graduate students from US universities obtain international research experience in social and hydrological sciences while working on a scientific problem with real-world implications.

Changes in climate cause communities to adapt to enhance resiliency and foster practices that are more appropriate for new conditions. In regions where dry seasons are increasingly long, the shorter rainy seasons experience more severe storms.

Rural and agricultural communities are especially vulnerable to new seasonal conditions and their resources for adaptation are limited.

The Dry Corridor of Central America (spanning parts of El Salvador, Guatemala, Honduras, and Nicaragua) is an important region for agriculture and needs adaptation strategies. The project location is ideal because of its many-decades history of changing climate.

The project participants work with local farmers and agricultural stakeholders to gain experience in adapting to climate change. The interdisciplinary scientists and development professionals work together in participatory research in communities experiencing water scarcity and extreme rainfall events.

Engineering Study Abroad: Joshua Turner, ’20, Cergy, France

Published May 24, 2019

By Kim Geiger

Growing up, Joshua Turner lived in four different states in the US, and visited over thirty of them. He loved traveling, but the only time he’d ever left the country was at nine months old, on a family trip to Canada. He longed to travel abroad, but finances and time always seemed to get in the way. Until he did a little more research. Turns out, it was entirely doable. Turner is now living his dream in Cergy, France, studying electrical engineering at ENSEA.

First, please tell us a bit about yourself.
I enjoy exploring outside—either going to the beach or hiking. I grew up in Houghton, near the Michigan Tech campus. I enjoy snowboarding in the winter, but it’s about the only thing I like about snow. I’m a member of the Ski and Snowboarding Club, and the Triangle Fraternity.

How did you get interested in Studying Abroad?
As an electrical engineering student, I always assumed it wouldn’t be possible to take any of the classes I needed while studying abroad. A few friends of mine had traveled abroad, though, and I realized I should try to actually talk with someone, just to find out if it could be possible for me, or not. So I met with Judy Donahue, my ECE academic advisor. Judy recommended I take a look at the French American Exchange (FAME) program at ENSEA,École Nationale Supérieure de l’Electronique et de ses Applications, in Cergy, France. She said I only needed to move around a couple of classes.

The cost was the next biggest concern of mine. I saved most of my money from an internship last summer, and from my on-campus job during the school year. I found out that I only needed to pay my Michigan Tech tuition for the program. All my financial aid and scholarships still applied. The only real extra cost was for the visa and the flight. I set up a budget once I got to France to make sure I’d be able to travel without worrying about running out of money.

ENSEA is one of the highest ranked engineering schools in France. It is focused solely on electrical engineering, with fewer than 1,000 full-time students. There are 14 American students in the FAME program. Classes are taught in English by the French professors. My largest engineering class had seven students and my smallest had four students. One class was spent entirely in the lab with both American and French students working together—a very cool experience.

Classes at ENSEA don’t have a set schedule. Each week can be completely different than the next. We check the schedule online regularly. Classes are at fairly consistent times, but it’s not uncommon to have a Monday class, for example, get moved to Wednesday or Thursday. This is sometimes beneficial. If a few of us want to travel over the weekend, we can ask the professor to move a Friday class to another day, earlier in the week.

Why did you choose France?
I was willing to go anywhere that would work with my degree program. Somewhere in Europe was my top choice. If I could go back and do it again, I think I would still choose France. It’s been such an amazing experience and the culture here is so unique and full of history.

What is it like living in Cergy?
Cergy is a suburb of Paris, host to six universities. Almost everyone here is either a student or commutes to Paris for work. Luckily, there is a train in Cergy that can get to the center of Paris in about 40 minutes. I purchased a monthly train pass which includes unlimited access to trains, buses, and metros within the entire Île-de-France region. I go into Paris a few times a week. I started off seeing the big tourist attractions. Then I started visiting less popular parts of Paris, places most tourists don’t have time to see. There are apps which make public transportation really easy to navigate.

In Cergy I stay at the housing provided by the university—an actual apartment. The bedrooms are rather large, and the kitchens are very tiny. It’s a 15 minute walk to ENSEA and a 20 minute walk to the train station. The parks and walking paths can actually be enjoyed in winter, since, unlike Houghton, they’re not covered by 15 ft of snow! We play soccer or basketball at one of the parks after class. Usually some French children will ask to join us—which is always super fun. I found two grocery stores, and shop with no difficulty finding what I was looking for. I’ve become accustomed to having baguettes (which cost less than 1 euro each) as a daily part of my diet.

Have you visited any other cities and countries?
I spend a lot of time experiencing all the different cultures of Europe. Every six weeks of classes are followed by a two-week vacation, so I have four total weeks of vacation. Some of the other students and I planned trips together. We have become really experienced at traveling. On the first break, I visited the Czech Republic, Austria, Hungary, England, and Scotland. Then on my second break, I went to the south of France to Toulouse, Marseille, Nice, and Monaco. After that, I went to Italy and visited Rome, Florence, Cinque Terre, and Milan. I also took a few weekend trips to Brussels, Strasbourg, and Mont-Saint-Michel. All in all, I will have visited over a dozen countries during this semester—way more than I used to think I’d visit in my entire life!

What is the most challenging part of the experience?
I am used to aiming for A’s and B’s and consider anything less to be disappointing. In France, the grading scale is from 0 to 20. Anything above a 10 is good. Almost no one gets a 20 and if you get a 16 it’s really impressive. Getting used to the grading scale was probably the most difficult academic adjustment for me at first, but after finding out you don’t need a 20—and that understanding the concepts is more important than the grade—it became easier to deal with.

The language barrier is, of course, a big challenge. I barely knew any French when I arrived. Luckily, all students at ENSEA learn English and some are very good at it. Now, near the end of the semester, I am to the point where I can usually get by while in Paris speaking only French. It is a very fulfilling feeling.

What are your plans for this summer?
Finals end the last week of May. Once those finish I will travel for a week to the UK and Spain before flying back to America. I then have about three weeks to relax at home before flying off to an internship/co-op with Nissan. I return to Michigan Tech in the spring of 2020, just two semesters left before graduation.

Engineering Study Abroad: Ryan Schrader ’20, Christchurch, New Zealand

Published May 24, 2019

By Kim Geiger

Ryan Schrader, a third year mechanical engineering student at Michigan Tech, ventured all the way to Christchurch, New Zealand to gain independence from his “comfortable bubble”. He’s there now, taking classes at the University of Canterbury. Schrader’s goal is to gain a new, multicultural lens—one he can share with others once he returns. He also wants to prepare himself for a future job traveling the globe. Read on to learn more about his adventure thus far!

First, please tell us a bit about yourself.
I fill up my time with studying, sports, hiking, and hanging with friends. I’m currently involved with the the American Society of Mechanical Engineers (ASME), the Tennis Club, Circle K (a community service organization). Although I am a mechanical engineer, I am also a member of Society of Environmental Engineers (SEEn). I love fall season in the Keweenaw. I also love the massive amounts of snow, but winter lasts a while. I figured I wouldn’t miss too much by traveling abroad.

How did you get interested in Studying Abroad?
I inherited an adventurous and explorative spirit from my parents. I first started looking at study abroad during my second year at Michigan Tech, but planned it for my third year, when my classes worked out well. I got very interested when I began hearing others share their own study abroad experiences.

What was your academic experience like in Christchurch, New Zealand?
The campus at the University of Canterbury in Christchurch is beautiful and I love it here. I’ve gotten some very clear and helpful lecturers, along with a few that are a bit more challenging. I enjoy meeting new classmates in my classes. The friendly lifestyle is rubbing off on me.

Why did you choose New Zealand?
I chose New Zealand after A LOT of research over places to go. It’s an adventurous island nation that speaks English! There were so many choices, but looking back on it, I really feel like I made the right choice. I also figured if I was going to be very far away from home, I might as well get far away as possible! A lot of encouragement came from fellow Michigan Tech students Jake Voss, and also Brady Severt whose photo on Roys Peak Track in Wanaka, New Zealand was used on the cover of University of Canterbury Study Abroad brochure.

What was it like living in Christchurch?
Christchurch is a big city of around 400,000 people, but I live west of the city in a smaller area. I can get some of the big city feel if I go downtown but can easily travel around New Zealand and get a small town feel in many places.

What was the best part of the experience?
Optimistically speaking, I believe my best experience might not have happened yet, since I’m still abroad! So far, though, my favorite experience has been a trip through Fjiordland, with its vast amount of wildlife and breathtaking views!

What was the most challenging part of the experience?
Okay, I’ll just admit it—my greatest challenge is finding a balance between my study time, and goofing off time! My goal is to make most out of the free time I have in order to pack in as much exposure to this diverse country as I possibly can!

Did you visit any other cities and countries?
I’ve traveled over to Oz (Australia) and it was really special. I’m planning on going to the Cook Islands, as well. In New Zealand, I’ve traveled well around the South Island and made a mark along the North Island.

What are your plans for this summer?
I’m not quite sure yet! I don’t get back until June 24th. I am adamantly looking for a position in Michigan—either around Ludington, Houghton or Detroit—that will help me with finances. I’m planning to graduate next spring. From there I’ll try to find a design role with my mechanical engineering degree.
