Les Cayes, Haiti: Engineering World Health

Five engineering students from Michigan Tech’s chapter of Engineering World Health visited Les Cayes, Haiti in May 2018. Making the trip were electrical engineering student Megan Byrne, biomedical engineering students Gina Anderla and Kiaya Caspers, mechanical engineering student Brooke Breen, and materials science and engineering student Anna Isaacson.

Early last summer, five undergraduate engineering students from the Michigan Tech chapter of Engineering World Health took a trip to Les Cayes, Haiti. They were led by Megan Byrne, an electrical engineering undergraduate who organized the trip. They describe the experience as nothing short of life-changing.  

Engineering World Health inspires, educates and empowers young engineers, scientists and medical professionals to use their engineering skills to improve global health in the developing world.  The Michigan Tech chapter of EWH is now in its second year.

Along with Byrne on the trip were biomedical engineering students Gina Anderla and Kiaya Caspers, mechanical engineering students Lidia Johnson and Brooke Breen, and materials science and engineering student Anna Isaacson. To get to Haiti, the Michigan Tech engineering students bagged groceries, plus each spent $1,500 of their own to cover travel costs. A non-profit organization operating in Haiti, HUT Outreach, provided lodging for the Michigan Tech team during their stay, and invited them to help teach STEM subjects to a class of 7th graders in the new HUT Outreach secondary school.

Students in Haiti often drop out of school in the sixth grade, with a diminishing retention rate thereafter. HUT Outreach is trying to break that statistic. During their visit to Les Cayes, the Michigan Tech team tried to change how the high school students viewed education and experienced learning.

“Project-based learning is a concept where students learn some theory, but also how to apply it outside the classroom, in the real world,” says Breen. “Our three day curriculum was focused around allowing Haitian students to think outside the box, being really inquisitive with hands-on learning projects. Our purpose was not only to expose them to a new way of thinking, but also to help HUT Outreach reform a new generation of Haitians who will be catalysts in creating a new way of approaching education in their country. Michigan Tech also gives us these tools and abilities—to be able to really hone in our leadership skills, and innovate ways to help create a better community around us, on a local-to-global spectrum.”

“Our EWH team wanted the students to learn the theory of series and parallel circuits, forces to build bridges, first aid, and how to build water filters,” says Byrne. “This was a challenge, because the students had not been exposed to any of these topics or hands-on learning, and they also spoke a different language.” Byrne is a peer mentor in the Learning with Academic Partners (LEAP) program for first-year engineering students in the Department of Engineering Fundamentals at Michigan Tech, which also provided support for the Haiti trip. Byrne was able put her LEAP experience to good use in Haiti.

“Thanks to our Haitian translator, Wesley, I was able to use a creative twist to help the students gain understanding of the difficult lessons in a way that would be impactful for them,” she says. “As a matter of fact, the lessons we taught in Haiti were very similar to LEAP sessions I have facilitated for first year engineering students at Michigan Tech.”

Using creativity, resourcefulness and critical thinking, EWH students from Michigan Tech repaired a broken oxygen concentrator, one of only two in the public hospital pediatric ward in Les Cayes, Haiti.

The Michigan Tech team also visited a local hospital, where they fixed a broken oxygen concentrator, one of only two in the hospital pediatric ward. They also discovered a potential fire hazard at the hospital—auto headlight bulbs used as replacement bulbs on medical lamps. And they noticed a lack of surge protectors to protect medical equipment during power outages.

The EWH team wants to return to Haiti this year to continue to help prepare the next generation of Haitian students, and provide support to the small community where we served. They also want to provide the woman’s center in Les Cayes with its first portable ultrasound machine.

“We really bonded with the community in Les Cayes,” says  Isaacson. “We want to help in any way possible to make their lives better. I think we can all agree that all the people of Haiti became our second family the minute we stepped into the country.”

Front row: Romana Carden, Allison Dorn, Amber Ronsman, Josie Edick, Mackenzie Brunet, Lauren Sandy, Jessica Geroux, Gretchen Hein

Seventeen members of the Michigan Tech chapter of the Society of Women Engineers (SWE) went to the national conference, WE18, October 18-20 in Minneapolis, Minnesota. 

Advisor Gretchen Hein (EF) accompanied the delegation of 13 undergraduates and four graduate students. Three students received travel scholarships: first-year chemical engineering student Josie Edick, second-year civil engineering student Amber Ronsman and Adedoyin Adedokun, a graduate student in electrical engineering. “Gaining close friendships with the other women in the Michigan Tech section was the best part about the conference for me,” Edick says. “I gained a ton of advice and insight, which made me very excited to get more involved in SWE back on campus.”

The WE18 conference was attended by more than 14,000 SWE members, both collegiate and professional, from across the nation, who enjoyed professional development breakout sessions, inspirational keynotes, a career fair and multiple opportunities for networking.

On the evening prior to the conference, the group attended a Michigan Tech alumni gathering in Minneapolis along with Dean Janet Callahan of the College of Engineering. Katie Buchalski, section president and fourth-year student majoring in environmental engineering, enjoyed the abundance of networking at the alumni gathering. “We all had something in common to talk about … Tech,” said Buchalski. “It was nice to learn what people do after college, and see how Tech forms a special bond between people and between generations.”

Michigan Tech alumna Dr. Kaitlyn Bunker received the SWE
Distinguished New Engineer Award at WE18. She earned a PhD, MS, and BS in Electrical Engineering at Michigan Tech, and is now a manager at the Rocky Island Institute in Boulder, Colorado.

The next day, at WE18, the students participated in professional development activities and presentations. Some volunteered at different events and participated in SWE-sponsored institutes. At the Celebrate SWE! Awards Banquet, Kaitlyn Bunker ’17 who earned a PhD in electrical engineering at Michigan Tech, received the SWE Distinguished New Engineer Award for “contributing valuable research and renewable energy solutions in the Caribbean, and to underserved communities; and for steadfast leadership at all levels of SWE.” Bunker is currently working at the Rocky Mountain Institute in Boulder, Colorado.

The Michigan Tech section received a Silver Collegiate SWE Mission Award, which recognizes a group that embody SWE core values.

Laura Schimmel volunteered at SWE’s outreach event for middle and high school girls, “Invent It. Build It.” Schimmel led a STEM activity for middle school girls–building “wind power plants” to lift a payload using cardboard, plastic bottles, straws, and tape. “I am taking a wind energy class at Tech right now,” says Schimmel, a fifth year double major in materials science and engineering and mechanical engineering. “I was thrilled to be able to share what I’ve learned and encourage the girls to pursue STEM in the future. There were hundreds of girls and countless creative solutions.”

Erica Coscarelli, a master’s student in environmental engineering, participated in the SWE Future Leaders (SWEFL) program. And along with Karina Eyre, Coscarelli went to the SWE Collegiate Leadership Institute (CLI), a day-long leadership development event. Both programs, led by engineers working in industry and academia, help college students gain leadership skills. “Participating in the SWE Future Leaders (SWEFL) program has been extremely beneficial for me,” Coscarelli says. “As part of the program we have monthly conference calls and complete our tasks with a buddy. At WE18 we were able to meet in person. It was great putting faces to names.”

Hein moderated a panel discussion, “Obtaining your First Academic Job/Academic Job Search”. Panelists were from a range of different types of universities and community colleges.

Michigan Tech SWE section counselor, Alumna Britta Jost joined the Michigan Tech attendees at the Celebrate SWE! Awards Banquet. Jost earned a Master’s in Mechanical Engineering 2004 and a BS in Mathematical Sciences in 2002, both at Michigan Tech, and works now as engineering project team leader at Caterpillar, Inc. 

The SWE students raised travel funds through their annual SWE “Evening with Industry” event, held each fall just before the Michigan Tech Career Fair. ArcelorMittal, Black & Veatch, and John Deere all provided support for section travel to WE 18, as well.

The best part about WE18?

“Through the SWE18 Conference I was able to secure an interview, and received an internship offer with Boeing in Washington State. If you would have told me as a freshman that I would have an offer with Boeing, I would have thought you were crazy. But being in SWE has given me the courage and experience to pursue opportunities I would have never thought possible.”
-Allison Dorn, third year student, mechanical engineering

“SWE18 exposed me greatly to American culture. I am ecstatic that I got to meet awesome women in academia and was able to interact with them both intellectually and professionally. Overall, the conference was a rewarding experience!”

City students learn environmental values during career tour at Tech

HOUGHTON — A group of 13 high school students from Detroit and southeast Michigan spent last week getting a firsthand look at the Copper Country and environmental and engineering programs at Michigan Tech.

Student often come to the program with ideas of careers they are interested in, and many of them aren’t focused on natural resources or ecology, said Lisa Perez from the US Forest Service Urban Connections. However, they typically walk away from the program with new ideas and shifted focus.

Perez and Mike Reed of the Detroit Zoological Society have worked with the students since the program began four years ago.

“It opened their eyes, maybe not to a totally different career path, but it opened their eyes to the fact that they are responsible for the future of the environment,” said Reed.
