Research Interests

My research focuses on the interactions among ecological processes, contaminant bioaccumulation, and effects on wild populations. I have specifically focused on (1) the ecological factors regulating contaminant bioaccumulation and trophic transfer, with an emphasis on food web processes and contaminant cycling, (2) land use practices and ecosystem restoration effects on contaminant cycling through food webs, and (3) the sublethal effects of contaminants on individuals and contaminant-induced impairment to reproduction in the wild. I broadly apply my research across taxa (primarily fish and waterbirds) and habitat types (including lakes, freshwater wetlands, agricultural fields, and estuarine habitats).
