GMES is proud to announce that Dr. Sananda Ray, who recently earned her PhD in Geophysics, Summer ‘25, has received the Dean’s Award for Outstanding Scholarship Award in recognition of her academic excellence, research achievements, and contributions to the Michigan Tech community.
Sananda’s doctoral work, conducted under the guidance of Dr. Radwin Askari, focused on generating and analyzing long-period seismic events to better connect theoretical models with natural volcanic systems.
“When looking for PhD positions, the program and project at Michigan Tech aligned with my research goals.” – Dr. Ray, when asked why she chose MTU.
Her research has been strengthened by international field experience, including work on Volcán de Fuego in Guatemala, where she gained hands-on skills in volcanic seismology. Outside the lab, Sananda enjoys photography, traveling, and building community among her peers.
GMES congratulates Dr. Ray on this well-deserved honor and looks forward to her continued contributions to the geoscience field.
If you ever wondered what it looks like when curiosity, grit, and global collaboration converge, let us introduce you to Dr. Gustavo Bejar-Lopez. As of August 8, 2025, Gustavo completed his final defense under the supervision of Dr. Greg Waite, Dr. Rudiger Escobar Wolf, with Dr. Luke Bowman, Dr. Snehamoy Chatterjee, and Dr. Jeffrey Johnson (Boise State), serving as committee members.
As a child in Ecuador, Gustavo Bejar-Lopez watched the eruptions of Tungurahua with fascination. A curiosity that led him to Michigan Tech’s GMES program to study volcanic hazards.
For his doctoral research, Gustavo focused on lahars, fast-moving volcanic mudflows, at Guatemala’s Volcán de Fuego. Using seismic monitoring, rainfall data, video observations, and computer models, he revealed how lahars generate distinct seismic signatures as they travel. He then developed a machine learning detection system to identify them in real time, improving early-warning potential for at-risk communities. His presentation title and abstract for the final Ph.D. research defense are listed below.
During his time at MTU, Gustavo earned the Outstanding Scholar Award, a Finishing Fellowship, and graduate certificates in Natural Hazards & Disaster Risk Reduction and Geoinformatics. He also won First Place in the 3MT competition and secured a National Geographic Explorer Grant to mentor students in the field. His work has been published in Scientific Reports through an NSF-funded collaboration on infrasound detection of lahars.
“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.”—Gustavo Bejar-Lopez
Dr. Bejar-Lopez’s story is more than an academic journey. It’s a testament to how one person’s passion can ripple through continents, classrooms, and communities. Whether facing volcanoes in Ecuador or Guatemala, his commitment remains the same: to bring knowledge, technology, and humanity together in the service of safety and resilience.
Congratulations, Dr. Gustavo Bejar-Lopez! Your dedication ensures that the communities living in the shadow of volcanoes are better prepared for the challenges they face.
Title: Water and Fuego: An Interdisciplinary Characterization of Lahar Activity on Volcán de Fuego, Guatemala
Abstract: Lahars are a type of volcanic hazard common in tropical stratovolcanoes. They occur when large amounts of water remobilize unconsolidated volcanic sediments, forming a mixture that flows violently downstream. In the case of Volcán de Fuego, Guatemala, lahars are mainly triggered by intense precipitation during the local rainy season. With dozens of these flows reported on Fuego during the rainy months, they pose a significant risk to people living near active lahar channels. This study aims to characterize critical aspects of lahar activity on Fuego using geophysical records, rainfall measurements, video observations, and computational simulations that help constrain the initiation and propagation mechanisms of these flows. This work shows that measured seismic energy increases and signal frequency content decreases while lahars move from proximal to distal areas of the volcano’s flanks. However, in the long term, seismic characteristics remain unchanged. This information supported the development of a machine learning-based framework to automatically detect lahar activity using geophysical monitoring. These results, combined with rainfall information, also allowed us to describe the control of precipitation on lahar activity. Statistically, rainfall at higher elevations is highly correlated with seismic parameters associated with flow size (e.g., cumulative power amplitude) farther downstream and least correlated with spectral characteristics of lahar signals (e.g., dominant frequencies), meaning rainfall alone is not sufficient to predict internal flow dynamics. This is consistent with a set of hydrologic outputs showing the significance that rainfall at higher elevations has in model accuracy. These results improve our knowledge of such ubiquitous types of volcanic processes and related hazards and can potentially be relevant for the development of mitigation strategies benefiting the communities around Fuego.
It is with deep sadness that we announce the passing of Professor Emeritus William (Bill) Rose on July 18. A distinguished colleague, devoted mentor, treasured friend, and visionary community leader, Bill began his journey with the Department of Geological and Mining Engineering and Sciences (GMES) in 1970, shortly after earning his PhD from Dartmouth College. He dedicated his entire 41-year faculty career to Michigan Tech and the Keweenaw community.
As department chair from 1990 to 1998, Bill led us through transformative growth, expanding graduate programs, increasing external research support, and integrating new technologies into geoscience education and outreach. He was instrumental in establishing signature programs such as the International Masters in Volcanology and Geotechniques (INVOGE) and the Peace Corps Master’s International program in Mitigation of Geologic Natural Hazards—initiatives that have significantly impacted our students and enhanced our global reputation.
Even in retirement, Bill remained deeply engaged, promoting public understanding of geoheritage and sharing his passion for science and culture with the broader community. His generosity, vision, and tireless mentorship have left an indelible mark on all who have had the privilege of knowing him. Many of his students returned decades later to reconnect, a testament to the lasting impact he had on their lives.
Our hearts go out to his wife, Nanno, his sons Christopher and Jason, and their families.
We recognize that no brief message can fully capture his profound impact or enduring legacy. In the coming days, we will share more information and plan a proper tribute to honor Bill’s life and contributions.

As part of our Spring 2025 celebration, we invited graduating students to share reflections on their time at Michigan Tech—from favorite moments to what’s next. Their insights highlight the experiences that shaped their journey and future.
I chose Michigan Tech and the GMES department because of the campus, the research opportunities, and the strong alumni network.
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.
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.
