When I arrived at WHOI, I was considered a microbial ecologist who specialized in characterizing the role of microorganisms in marine ecosystems. Since then, I have sought to address questions in organic geochemistry. While these two fields may seem quite disparate, my current research interests involve both microbial ecology and organic geochemistry. Microorganisms both consume and produce dissolved organic matter. On the other hand, the presence of specific organic compounds may deter or attract microorganisms. A significant component of my research seeks to address the challenge of characterizing the linkage between the activity of microorganisms and the in situ composition of organic matter.
 
My research interests can be summarized into four areas. Details about specific projects are available by following the links to the left.
  1. Metabolic activity of microbes
  2. Interactions between microbes and larger organisms
  3. Microbiology and organic geochemistry of the deep-sea
  4. Organic matter in groundwater
In addition to my own research interests, I am also a member of Liz Kujawinski's laboratory where I work on projects related to metabolomics and the development of new algorithms to analyze data from ultrahigh resolution mass spectrometers.
