Summary
👤
Senior🎓
Top SchoolColin Penn is a hydrologist with a decade of hands-on experience blending field work and physically based hydrologic modeling, currently supporting alpine research programs at the USGS Colorado Water Science Center. He holds an MS in Hydrology from Colorado School of Mines, where his thesis used ParFlow to quantify how mountain pine beetle tree mortality alters mountain water-cycle dynamics. Comfortable installing and managing continuous sensor networks and discrete sampling campaigns, he pairs field instrumentation expertise (Campbell dataloggers, YSI sondes, ISCO autosamplers) with modeling and analysis skills in ParFlow, MODFLOW, HEC-HMS, MATLAB, and R. Colin’s background spans ecology, limnology, contaminant transport, and GIS, enabling interdisciplinary approaches to water-resource questions from plot to watershed scales. He enjoys projects that tightly integrate field observations with numerical experiments, translating complex alpine processes into actionable science for research and resource management.
