I am broadly interested in research at the interface of hydrology, geochemistry, and ecology.

Past

My past research has addressed potential pathways of nitrogen (N) and phosphorus (P) transport in lakes and streams. This has incorporated field measurements of the physical, chemical, and biological environment within the lakes and streams. Prior to coming to the University of Minnesota, I was given an opportunity to focus on microbial/nutrient dynamics, while completing my Master's degree under Dr. Chris Fritsen. The results from that research stimulated my current research, which addresses the basic processess that determine the spatial variation of N:P balance between and within lotic ecosystems.

Present

I am a Ph.D. student in the Water Resources Science graduate program, and am co-advised by Dr. John Nieber and Dr. Dong Wang. My current research addresses how hydrologic processes influence nutrient dynamics in lotic ecosystems. Specifically, I am investigating how hydrologic regime (relative importance of sub-surface versus surface transport of water and solutes) influences N:P ratios in the surface waters of lotic ecosystems. I am using numerical watershed models, statistical analysis of field observations, and a paried watershed study to evaluate the relationship between hydrologic regime and N:P balance in Midwestern streams.
