Academic Areas of Interest

I have several areas of research interest. The first is understanding the molecular control of development and function of a subclass of T lymphocytes called gamma delta T cells in Xenopus laevis (the African clawed frog). A second area of research interest is the identification of the signaling processes involved in the response of the flatworm, planaria, to light. We have evidence that histamine is a neurotransmitter involved in this response, and are evaluating the precise mechanisms by which histamine is required for this response. I am also studying regeneration using planaria as a model system for tissue regeneration. When planaria are cut into pieces, each piece regenerates an entire body including head and tail. I am interested in the role of the Wnt signaling pathway in regeneration, as well as the role of the innate immune response in these processes. Another area of interest is in the effects of stress and exercise on immune response.
