Jongeun You
Postdoctoral Fellow
Now: Assistant Professor at Northern Michigan University
Jongeun You served as a Postdoctoral Fellow in the Hydrologic Science and Engineering Program at the Colorado School of Mines. At the Marshall Lab, he conducted research to advance scientific understanding of changing water and climate, particularly with respect to hydropower. Dr. You also has expertise in water sector cybersecurity and energy infrastructure siting conflict. Dr. You holds a Ph.D. in Public Affairs from the University of Colorado Denver, an M.P.P. from the University of Michigan, and a B.A. in Economics from Seoul National University.
Brian Pfaff
M.S., Hydrologic Science and Engineering, Colorado School of Mines, 2021-2023
Now: Engineer/Hydrogeologist at Knight Piésold
Upon graduating with his B.S. 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.
