Bonnie Bassler is a professor of molecular biology at Princeton University. She has made important discoveries about quorum sensing, or the process by which single-cell bacteria communicate with one another. She hopes to use quorum sensing to create anti-microbial drugs to counteract bacteria. For her work, she received a MacArthur Fellowship in 2002 and the National Academy of Sciences elected her one of its members in 2006. She wakes up prior to 6 a.m. everyday to teach an aerobics class.. because otherwise she would just be lazy.
