Research Interests

I am a marine geochemist who works on broad biogeochemical problems through collaboration with interdisciplinary teams. My work involves both ship based fieldwork and laboratory based analyses and experiments.

Over the course of my career I have made significant contributions to the understanding of active hydrothermal deposit formation and alteration. I currently work closely with biologists and microbiologists to understand the interactions between microbial and macrobiotic communities and seafloor mineral deposits. A particular focus is on the biological impact on diagenetic processes and chemical fluxes within and around active and inactive hydrothermal systems. 

More recently we have used sediment geochemistry to test the validity of newer proxies and to quantify boundary fluxes of trace metals in the South Atlantic.
