My research focuses on using trace elements and stable isotopes in the marine environment as a tool for understanding marine biogeochemical and paleoceanographic processes, as well as the history and severity of anthropogenic contamination. It addresses environmental concerns, and is multi-disciplinary in scope.

My primary research interest is to reveal the history of past climate changes. I am exploring the utility of a proxy for sea surface temperature based on the incorporation of Mg into the shells of foraminifera and ostracodes. The reconstruction of ocean temperature is an essential component in understanding the controls of past and future climate change throughout Earth's history.

Another of my active research projects is trace element speciation in aquatic systems, an essential component to understanding geochemical behavior and bioavailability of trace metals.
