In the past, her research has used a combination of remote sensing, geospatial analysis, and numerical modeling methods to examine issues of glacier change and water resource management. Her interest in glacial systems stems from a backpacking and sea kayaking trip in Alaska she took during high school, where she was overwhelmed by the size and beauty of the glaciers she saw. In her free time, she enjoys hiking, biking, landscape photography, and spending time with her dog, Parker.
Gui Guenther Aksit graduated from Ohio University with a B.A. in Anthropology and from the University of Washington with a B.S. in Earth and Space Sciences: Geology. At UW, she researched the geological evolution of western Anatolia during the Late Cretaceous and early Paleogene through detrital zircon geochronology and sandstone petrography. After graduating, she interned at the Cascades Volcano Observatory, researching the explosive eruptive histories of Glacier Peak and Mount Rainier. Gui is thrilled to start working with Meredith Townsend on dike propagation and magmatic plumbing systems in the San Juan volcanic field. When she isn’t at the library or a coffee shop studying, Gui loves climbing, running, painting and nerding out about the latest sci-fi releases in print or on screen.
Rebecca Bussard is from Oxford, PA and received her B.S. in Physics at Penn State University. At University of Oregon, she is excited to join Estelle Chaussard‘s lab to study Mt. St. Helens’ previous eruptions using various remote sensing techniques. During her time as an undergraduate, she used satellite imagery to study the eruptive activities of various Nicaraguan volcanoes. Her research primarily focused on the persistently restless volcano Telica and analyzing the deformation that occurred during the volcano’s explosive periods in 2015. Outside of the lab, she enjoys running, baking, and making the most of her Netflix subscription. Having lived on the east coast her whole life, she’s excited to be living on the west coast for the first time.
Avigyan Chatterjee grew up in the small town of Asansol in the historically famous province of Bengal in India. He received his B.S. and M.S. in Earth Sciences from one of India’s premier science research institutes, the Indian Institute of Science Education and Research Kolkata. His M.S. work revolved around exploring the mechanics behind the frequently occurring small earthquakes in the seismically complex region of Northeastern India. As part of his project work, he has been actively investigating the physics behind the large earthquakes, analysing near-field and far-field seismic data in the Japanese and Sumatran subduction zones. In continuance of his interests in earthquake source theory and numerical modeling, he will be working with Amanda Thomas starting this Fall. Outside his research work, he likes to play his acoustic guitar, read historical novels, and watch football.
Ana Colón grew up in San Juan, Puerto Rico, and graduated in 2018 from Dartmouth College with a B.A. in Earth Sciences and Astronomy.

UO Earth Sciences hosts 2nd Annual Volc-OR conference!

The 2nd annual Volc-OR (Volcanology Students of Oregon) conference was held at the University of Oregon, April 11-12, 2019. Over 60 students from 4 regional universities and colleges attended and nearly half presented their research in oral or poster sessions. Laboratory tours of the facilities at UO, science communication workshops, and panel discussions rounded out the 2019 edition of Volc-OR, which culminated in a keynote by Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory.

To learn more about the group and our annual conference, please visit:

From the Volc-OR website:
Volc-OR aims to bring together graduate and undergraduate students from Portland State University, Oregon State University, the University of Oregon, and other regional universities whose research relates broadly to volcanology (e.g. physical volcanology, igneous petrology, economic geology, volcano geomorphology, geophysics, etc.). As a more informal complement to major national scientific meetings, we hope that this small student-centric and student-led meeting will provide focused and relevant learning experiences and discussion, and foster new connections, collaborations, and friendships.

Importantly, we feel that we can all be taking better advantage of our shared interests and close proximity with one another to bolster research ideas and access to analytical facilities. Through meetings and general volcanophile camaraderie, the goal of Volc-OR is to build these bridges to meet your neighboring students and faculty!
