RESEARCH INTERESTS

  • Marine Carbon Chemistry
  • Isotope Geochemistry 
  • Climate Change and Ocean Acidification

Methane released into the water column can be oxidized aerobically or anaerobically to inorganic carbon and potentially lead to changes in ocean chemistry. I am interested in understanding and quantifying the effect of methane hydrate dissociation on the marine carbonate system. Furthermore, I am interested on developing new analytical techniques to determine sinks and sources of methane and carbon dioxide.
