I am interested in the mechanisms whereby the multicellular prokaryote, Myxococcus xanthus, engages in contact-mediated cell-to-cell signaling. The efforts of my laboratory have focused recently on the nature and role of the extracellular fibrils, on the roles of tyrosine kinase, and on fibril-bound ADP-ribosylation.

I am also collaborating with Dr. David Sherman on the isolation of marine myxobacteria that produce novel bioactive agents.
