Areas of Expertise

  • Biological Chemistry & Pharmacology

Education

  • Ph.D., 1996, University of California, Los Angeles
  • Postdoctoral, University of Pennsylvania, 1997-2001

Current projects:

Trainee projects in the Bell lab will focus on understanding the structure and mechanism of DNA repair proteins using x-ray crystallography and other biochemical and biophysical tools. A particular area of emphasis is on viral recombination proteins involved in the single strand annealing pathway.
