Biography
Dr. Bornali Bhattacharjee, MS, PhD is a Research Associate Scientist at the Department of Immunobiology and the Associate Director at the Center for Infection & Immunity. Her role is to lead, coordinate and manage biomedical research projects that are geared towards understanding the immune trajectories of post-acute infection syndromes.
Her training and research interests lie at the interface of pathogen genomics, evolutionary biology and host-pathogen interaction. She earned her PhD in Molecular Epidemiology & Virology from Indian Statistical Institute & University of Calcutta. Her post-doctoral training was in Viral Genomics & Evolution at University of Massachusetts Medical School.
