  • 1998-2002 Postdoctoral Scholar, The Salk Institute for Biological Studies. Advisors: Joanne Chory and Detlef Weigel.
  • 1998 Ph. D. University of California, San Francisco. Advisor: Cynthia Kenyon.
  • 1989 B. A. Haverford College.


One of the things that I enjoy about being in Davis is close proximity to the Sierra. For photos of some of some of my adventures there and elsewhere, please visit my simple photo gallery.
