Rhishita Chourashi, Ph.D.

Rhishita completed her doctoral work at the National Institute of cholera and Enteric Diseases under the mentorship of Dr. N.S. Chatterjee. Her thesis work focused on understanding chitin-dependent regulation of gene expression in Vibrio cholerae, with a specific focus on how this regulation affected expression of the type 6 secretion system (T6SS). Rhishita joined the Oglesby laboratory in April 2020. She is currently studying how iron and PrrF affects T6SS expression in Pseudomonas aeruginosa.
