Graduate students

Arielle Koshkin
Ph.D. Student, Hydrologic Science and Engineering, Colorado School of Mines, 2022-Present
M.S., Hydrology, University of Nevada, Reno
B.A., Biology, Carleton College
Arielle is a PhD student interested understanding how climate change is altering snowpacks and the impacts that has on our water resources. Her research focuses on understanding the post-fire impacts on snow hydrology in western United States. Arielle received a M.S. in Hydrology from the University of Nevada, Reno and a B.A. in Biology from Carleton College. In her free time, she loves to explore the mountains by bike, foot, or ski and relax with a cup of coffee in her favorite mug.

Brian Pfaff
M.S. Student, Hydrologic Science and Engineering, Colorado School of Mines, 2021-Present
B.S. Environmental Geoscience (minor geography), University of Utah, 2018
Upon graduating in 2018, Brian worked in the environmental consulting industry for a few years before deciding to pursue a Masters’ degree in Hydrology. For his thesis, Brian is interested in how various topographic distributions affect the timing/magnitude of snowmelt and runoff at the catchment level and what this can tell us about a watershed’s sensitivity to climate change. In his free time, he enjoys skiing, mountain biking, and generally doing anything outdoors.

Alexa Yeo
Co-advised with Eric Anderson
M.S. Student, Hydrologic Science and Engineering, Colorado School of Mines, 2022-Present
B.S. Civil and Environmental Engineering, University of Illinois at Urbana-Champaign, 2020
Alexa got her bachelor’s degree in civil and environmental engineering with a focus on water resources engineering at the University of Illinois at Urbana-Champaign. After working as a consulting engineer for two years she is now pursuing a master’s degree in hydrology at Colorado School of Mines. Her research interests include hydrologic model accuracy and forecasting, climate change, limnology, and science communication.
