Research Interests

  • Sulfur biogeochemistry
  • Climate change impacts on marine phytoplankton
  • Algal community structure and biogenic sulfur production
  • Application of sea-going mass spectrometry “-omics” technologies to phytoplankton ecophysiology
  • Microbial oceanography and sulfur biogeochemistry

Current research projects

  • The role of vitamin B12 of the marine environment and specifically, the biogeochemistry of the climatically important compound dimethylsulfide and its precursor dimethylsulfoniopropionate

  • The application of Membrane Inlet Mass Spectrometry (MIMS) and Proton-Reaction-Transfer Mass Spectrometry (PTR-MS) to the determination of gases and volatile organic compounds in aquatic environments

  • Environmental Proteomics and Metabolomics: Developing and linking “omics” tools to classical approaches in biogeochemistry to better understand biogenic sulfur production in marine microbes

  • Developing experimental methodologies and technologies for assessing the impact of climate change variables on lower trophic level organisms

  • Applying mass spectrometric, proteomic, and metabolomics tools along with the study of aquatic biogeochemistry and formation of volatile organic compounds by aquatic microbes to astrobiology and the detection of extant organisms on other worlds
