Ecotoxicology and biogeochemistry of environmental pollutants.
Ph.D., University of Minnesota
I study mercury cycling in inland habitats including stream and river, lake, wetland and forest. Mercury is a highly toxic metal, but it is present in all ecosystem types due to long-range atmospheric transport and deposition. I use concentration and speciation analyses to quantify the levels of mercury present in different types of environmental matrices including water, sediment, soil and biota. I also use stable isotopes of mercury to better understand the sources and transformation of mercury in the environment. I have worked on various projects as related to mercury cycling in “natural” ecosystems. Recently, I have started to examine the effects of environmental perturbations — namely forest wildfire, prescribed burning/forest thinning, and saltwater intrusion to coastal wetlands, as an effort to better understand the effects of global climate change on mercury cycling. In addition, I am interested in studying the toxicity and cycling of other pollutants such as heavy metals, pesticides and organic chemicals in the environment.
