My research seeks to understand the processes that affect trace element and nutrient cycling in the hydrologic system. Current projects include:

1) water chemistry in alpine watersheds

2) phosphorus fluxes from sediments in shallow lakes

3) mercury and other trace metals in glacial meltwater

4) mineral dust emissions and deposition



How are local dry lakes impacting air quality and human health?
