I apply environmental chemistry in the cryosphere – the frozen water domain – to document global change of glacier and snow melt in mountainous and polar regions. My research explores the impact of aerosol deposition to the surface of snow and ice, and the resulting impacts on spectral albedo, melt and water quality. I completed my PhD in August 2016 in Civil and Environmental Engineering at the University of Colorado – Boulder, while working at the Institute of Arctic and Alpine Research, an interdisciplinary research institute focused on documenting environmental change in the polar regions. I then worked as a Postdoc at the National Snow and Ice Data Center in Boulder, CO with a primary focus on water and snow chemistry in High Mountain Asia as part of a USAID funded project. I have studied snow packs, lakes and reservoirs in Colorado, and glaciers, snow packs, and lakes in the Arctic, Antarctic, and the Himalayan, Andes and Rocky Mountains. Along with maintaining polar research, I look forward to delving into local and regional studies in the Pacific Northwest.
