Research Interests

Glenn is an MD/PhD student in the Molecular Genetics & Microbiology Graduate Program. Glenn's research focuses on understanding the mechanisms by which bacteria cause disease. Specifically, Glenn has been working on the chaperone/usher (CU) secretion system in Escherichia coli. This secretion system is the pathway by which bacteria assemble and secrete structures, termed pili, onto their surfaces. Uropathogenic strains of E. coli use pili to adhere to human kidneys and bladder, causing urinary tract infections (UTIs). Because clinical treatments for UTIs are becoming less and less effective due to bacterial resistance, development of new clinical therapeutics is crucial. Glenn has made important advances in his field including the discovery of a new mechanism by which the CU pathway is maintained in an inactive state, until it is selectively mobilized. This mechanism likely serves to ensure that pili are assembled correctly, and that their adhesive portion is always located at their tip, in a position to adhere to the urinary tract and cause UTI. These findings open up new avenues for the exploration of therapeutic interventions. For example, drugs that maintain the usher in its inactivated state, by a similar mechanism to the one Glenn has discovered, could hold promise as effective treatments for UTIs.
