Complete Curriculum Vitae

EDUCATION

Ph.D., Marine Biology, June 1999., Scripps Institution of Oceanography, Marine Biology Research Division, University of California, San Diego.

B.A., Biology, magna cum laude, June 1990, Robert D. Clark Honors College, University of Oregon, Eugene

RESEARCH INTERESTS

Interactions between invertebrates and associated bacteria (symbionts, parasites)
  ·  negotiation and establishment of bacterial colonization involving
     the innate immune defenses.
  ·  bacterial symbiont influences on host developmental changes
  ·  host cell-bacterial cell recognition and binding (receptors and adhesins)

Ecology of bacteria associated with hosts: the study of complex communities residing in invertebrates and vertebrates.
