I was born and raised in Fairbanks, Alaska where I learned to appreciate the outdoors, nature, and cold climates. Although I spent the majority of my growing up years in Alaska, my father was a professor and took sabbatical leaves where I lived in Switzerland and Arizona. Since leaving Alaska I've lived in Utah, Minnesota, California, and South Korea. I've lived in Butte since 2009, which is sort of like coming to my second home because my parents grew up here and my grandfather received a B.S. and M.S. in Metallurgical Engineering from Montana Tech.
My research focuses on investigating groundwater and surface water interactions in mountain systems. Both my M.S. and Ph.D. research focused on using environmental tracers and isotopes to investigate how groundwater interacts in with surface water, but current research also includes physical hydrologic field methods and groundwater flow modeling. I am interested in estimating groundwater residence times, cycling rates and flows, as well as identifying source waters within mountain catchments. Since 2015 my research focus has expanded to studying how river restoration impacts mountains rivers. Past projects have included contaminant transport, mine hydrology, leaky irrigation canals, mountain front recharge, and lake/groundwater hydrology.
I enjoy mentoring students in both teaching and research. This includes teaching and working with students to the point that they become independent thinkers and learn how to solve problems. It may be building on homework assignments in a class so that they can successfully complete a design project or it may be aiding in the thought process for completing a research project.

I enjoy hiking, running, or going to the gym to un-stress. Since the summer of 2015 I have DJed a weekly two-hour volunteer radio show on Butte America’s local community radio station, where I play share my favorite music. I also travel all over the western U.S. to attend concerts. I enjoy cooking and studying Korean.
