PI: Adrienne Marshall

Assistant Professor, Hydrologic Sciences & Engineering; Geology & Geological Engineering

Adrienne Marshall is a computational hydrologist interested in snow, ecohydrology, permafrost, and hydropower. Her research interests are united by a desire to understand how climate change is altering water resources, and solutions to these problems from both adaptation and mitigation perspectives. Dr. Marshall holds a Ph.D. in Water Resources from the University of Idaho, an M.S. in Energy and Resources from U.C. Berkeley, and a B.A. in Biology (French minor) from Scripps College. In her spare time, she enjoys exploring Colorado’s incredible trail system, gardening, and painting.

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.
