Discover how one Michigan Tech graduate leveraged international connections, hands-on fieldwork, and interdisciplinary learning to launch a career in natural hazards research. With skills in machine learning, project management, and collaboration with global agencies like INSIVUMEH, he is not just studying volcanoes—he is preparing to protect lives.

Gustavo in action, helping install a tiltmeter—an instrument that measures ground deformation—on the flanks of Volcán de Fuego in Guatemala. He was less than a mile from the crater, collecting real-time data from one of the most active volcanoes in the world! This unforgettable field experience happened in February 2025, and it’s just one example of the kind of hands-on, high-impact work you can do as a student here!

Here’s the lowdown from Gustavo Bejar-Lopez.

Q: What made you choose Michigan Tech and the GMES department?
A: I already knew about Michigan Tech during my undergraduate because a few of our professors back home in Ecuador (Yachay Tech) were Michigan Tech graduates. Eventually, when I was applying for grad school, I learned about research projects at GMES. One of these projects was the lahar project, led by Dr. Rudiger Escobar-Wolf, which involved extensive fieldwork —a task I had been eager to undertake.

Q: What was your favorite class or project in GMES?  
A: I liked the Social Dimensions of Natural Hazards class because when I took it, the class was comprised of students with very different backgrounds and experiences with natural hazards. It was enriching to learn about these different perspectives on things I had not experienced myself.

Q: What’s next for you after graduation? (Job, grad school, travel, etc.)
A: Currently applying for postdoctoral research and teaching positions mostly aligned with natural hazards or environmental seismology.

Q: How do you hope to make a difference in the world with your degree?
A: While my work was related to the technical aspect of detecting and modeling hazards, it has important implications for the lives of people who are exposed to or affected by these hazards every day. I plan to continue developing new tools and expanding my knowledge of these geologic processes, thereby diversifying my expertise to include other types of hazards, beyond the focus of my PhD, which is lahars.

Q: What unique opportunities did you find at Michigan Tech that you might not have found elsewhere?
A: I was able to work in collaboration with other agencies, mainly INSIVUMEH (the local geophysical monitoring agency in Guatemala). This close collaboration enabled me to gain a deeper understanding of the work conducted in volcano observatories and establish a network with local scientists in Guatemala. Additionally, I was able to attend an international conference and participate in field experiences thanks to the funds provided by scholarships and grants available at Michigan Tech, such as the GSG Professional Development Travel Grant.

Q: What skills did you gain in the program that you’re already using (or excited to use)?
A: Before my PhD, I had very little knowledge about programming, mainly limited to MATLAB. While at Tech, I learned to use Python and develop machine learning methods using that platform, as well as analyze time series and perform signal processing. I had the chance to get my own research grant and learned to manage my own project, which expanded on the work on lahars in Guatemala.

Q: What advice would you give to incoming GMES students?
A: Take notes of all the opportunities available for you as a grad student. There is always a grant or scholarship available for which you can apply to conduct fieldwork or attend a conference. If you’re unsure where to find them, ask the professors or department staff for assistance. That, and bring warm clothes.

Mining Engineering MS graduate Poorva Kadrolli ’22 reflects on what drew her to Michigan Tech, the skills she’s proud to carry forward, and her advice for those just starting out.

Q: What made you choose Michigan Tech and the GMES department?
A: The Campus, research background, and a strong Alumni base. The curriculum and staff are also very impactful in building a successful career.

Q: What was your favorite class or project in GMES?
