Associate Professor Laurie Comstock

Laurie Comstock is an Associate Professor at Harvard Medical School with a primary appointment in Infectious Diseases at Brigham and Women’s Hospital.  With a background in bacterial pathogenesis and genetics, she began a new research direction more than 20 years ago studying the Bacteroidales, the most abundant order of human gut bacteria.  Her lab has made fundamental discoveries regarding the biology of these important gut bacteria.  Her lab is currently engaged in studying the ecology of the mammalian gut microbiota, specifically studying how abundant bacterial members of this ecosystem compete with each other through the production of secreted bacterial toxins.  Her lab has identified new families of bacterial toxins, many of which form pores in sensitive bacterial cells.
