Overview

Bonnie Bassler spends her professional life eavesdropping on bacteria. "We scientists were all wrong thinking that bacteria live asocial, reclusive lives," she says. "There isn't any way they could accomplish the terrible and the wonderful things they do on earth acting as individuals." In fact, bacteria are gregarious by nature, preferring to crowd together in complex, multi-species communities, whether on abiotic surfaces or living tissue. They are superbly well adapted to lives of infinite uncertainty and intense competition. The ability to communicate and cooperate goes a long way toward ensuring their survival.

Bonnie Bassler, who was elected to the National Academy of Sciences in 2006, is a Howard Hughes Medical Investigator and professor of molecular biology at Princeton University. She received a BS in biochemistry from the University of California at Davis and a PhD in biochemistry from Johns Hopkins University. Bassler performed her postdoctoral work in genetics at the Agouron Institute, and joined the Princeton faculty in 1994 where she is the Director of Graduate Studies in the Department of Molecular Biology. The research in her laboratory focuses on the molecular mechanisms bacteria use for intercellular communication in a process called quorum sensing.

Bassler was awarded a MacArthur Foundation Fellowship in 2002. She was elected to the American Academy of Microbiology in 2002 and made a fellow of AAAS in 2004. In 2003 Bassler received the Theobald Smith Society Waksman Award and is the recipient of the 2006 ASM Eli Lilly Investigator Award.

Bassler is an editor for Molecular Microbiology and Annual Reviews of Genetics, and an associate editor for the Journal of Bacteriology. She serves on grant, fellowship, and award review panels for the NSF, ASM, AAM, Keck Foundation, and the Burroughs Wellcome Trust.
