Research Interests

The biogeochemistry of sulfur, nitrogen and carbon. Specific areas of focus currently include:

  1. The role of vitamin B12 of the biogeochemistry of the climatically important compound dimethylsulfide and its precursor dimethylsulfoniopropionate
  2. The application of Membrane Inlet Mass Spectrometery (MIMS) and Proton-Reaction-Transfer Mass Spe3ctrometry (PTR-MS) to the determination of gases and volatile organic compunds in aquatic environments.
  3. Proteomic and metabolomic approaches to understanding biogenic sulfur production in marine phytoplankton
  4. Impact of climate change variables on natural phytoplankton assemblages and cell-specific intracellular dimethylsulfoniopropionate quotas
  5. Developing experimental methodologies and technologies for assessing the impact of climate change variables on lower trophic level organisms
