RESEARCH INTERESTS

  • Isotopic Fingerprinting and Radiocarbon Analyses
  • Trace Metal and Greenhouse Gas Dynamics
  • Marine Biogeochemistry
  • Ocean and Groundwater Chemistry

I investigate biogeochemical processes in environments ranging from marine systems to hyper eutrophic freshwater lakes, that are both uninfluenced, as well as heavily influenced (e.g., oil spills) by anthropogenic activities. My research includes understanding the dynamics of greenhouse gases (methane, carbon dioxides, etc), trace elements, organic carbon, nutrients, and chemical pollutants (e.g., poly-aromatic hydrocarbons). I am also interested in developing new advanced techniques for chemical analysis and finding new proxies for biogeochemical processes, as I help to advance our knowledge of coastal processes and how they are influenced by climate change.
