My research interests rest on marine isotope geochemistry. In particular, I am interested in trace elements and their isotopes in the ocean, and their roles as tracers in the modern and past ocean for circulation, fluxes, sources and sinks, and biogeochemical processes. My current projects involve the usage of radioactive isotopes (Th), radiogenic isotopes (Nd, Sr, Pb), and non-traditional stable isotopes such as Cd and Ba from marine sediments, seawater, and suspended and sinking particulates.

I am currently recruiting graduate students and postdocs. Please contact me directly if you are interested in joining my group.
