Bhaswati Sen, PhD is an instructor in the Department of Microbiology & Immunology at Drexel University College of Medicine.

Research Overview

Dr. Sen is the lab manager of the Genomics Core Facility of Drexel University College of Medicine and a member of the Center for Advance Microbial Processing.


Area of Research

Dr. Sen’s research interest is on the molecular microbiology of bacterial pathogenesis and the next generation sequencing particularly regarding species-specific microbiome studies and comparative bacterial genomics. Her research addresses some of the most pressing issues in understanding how to treat bacterial infections using knowledge of bacterial processes and metabolism; a pursuit that encompassed treatment of tularemia, hospital-borne infections, middle-ear infections and chronic obstructive pulmonary disease in adults, among other ailments. Her graduate study included the evaluation of new-generation serologic tests for the diagnosis of typhoid fever, using data from a community-based surveillance study in Calcutta, India. She utilizes the Next Generation Sequencing for understanding bacterial pathogenesis and virulence with a focus on microbiome and bacterial genomics.
