Research Interests:
My research focuses on understanding the mechanisms that drive the structure, function and movement of chemicals through food webs, which I call trophic ecology (defined here as involving the feeding habits or food relationship of different organisms in a food web). Trophic ecology includes the transfer of chemicals, both good (e.g., essential fatty acids and trace elements) and bad (e.g., PCBs and mercury), through food webs or ecosystems.
