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 making art.

Sushma Kadel

M.S. Student, Geological Engineering, Colorado School of Mines, 2024-Present (co-advised, Gabe Walton)

M.Sc., Applied Geology, Tribhuvan University, Nepal

B.Sc., Geology, Tribhuvan University, Nepal

Sushma is an M.S. student researching long-term rockfall trends and the potential impacts of climate change on Colorado’s transportation network. Her work utilizes statistical models and future climate scenarios to forecast rockfall hazards and inform adaptation strategies for the Colorado Department of Transportation (CDOT). She has prior experience in geological mapping, landslide modeling, and disaster management. Outside of research, Sushma enjoys hiking, exploring mountains and writing poetry.

Christy Hutchins

M.S. Student, Hydrologic Science and Engineering, Colorado School of Mines, 2025-Present

B.A. in Geology, Occidental College, 2019

Christy is a M.S. student whose research focuses on evaluating how the National Water Model (NWM) performs in regulated river systems, specifically analyzing the impact of reservoir operations on streamflow prediction accuracy. Prior to Mines, she worked at the USGS specializing in spatial analysis and environmental data management. In her free time, Christy enjoys skiing, backpacking, and visiting every museum she can.
