Prior to this, Bohannan was a tenured Associate Professor in the Department of Biological Sciences at Stanford University. He earned his PhD from Michigan State University in 1997 under the mentorship of Richard Lenski.

He has been a co-principal investigator on research teams supported by multi-million dollar grants from the National Institutes of Health to explore the health benefits of microbes and to study how the microbiome influences social behaviors and vice versa.

Bohannan is a fellow of the Ecological Society of America, the American Academy of Microbiology, and the American Association for the Advancement of Science. In recognition of his research accomplishments, he is a recipient of the Humboldt Research Award from the Alexander von Humboldt Foundation. He was also in the inaugural class of Google Science Communication Fellows.
