Amanda Lewis, Ph.D.

My lab is interested in the roles played by bacteria during colonization and pathogenesis of the female genital and urinary tracts. We build novel model systems to understand how bacteria thrive and co-exist within these varied niches and how such interactions influence states of health and disease in animal and human hosts. We also investigate the roles played by complex carbohydrates of the host and bacteria, as well as enzymes that degrade them during bacterial colonization and infection.
