Detailed Research Interest : 

Heavy stable isotope geochemistry

Geochemical tracer development

Transport, transformations

Environmental fate of metals/metalloids

Current Research Interests: 

My research interests lie in natural biogeochemical cycling of metals and assessing the importance of anthropogenic activities as metal sources. Metal emissions to the environment from anthropogenic sources may be much larger than those from natural sources. These anthropogenic inputs disturb the natural biogeochemical cycling of many elements. My research aims to characterize the isotopic variation among metal sources and to quantify the extent to which reactions (physical, chemical and biological) cause isotopic fractionation of heavy stable isotopes, with the goal of developing these isotope systems as tools for source and process identification. Ultimately, my research seeks to aid environmental monitoring and remediation efforts and improve our understanding of natural and disturbing biogeochemical cycles.
