Profile

Divya completed her Bachelor of Science and Master of Science in Microbiology from Pt Ravishankar Shukla University, India. She pursued her doctoral degree at National Institute of Immunology, New Delhi India and subsequently moved to Weill Cornell Medicine, New York NY, USA to pursue her post-doctoral studies. Following this, she moved back to India and had a brief career in research administration where she worked as Grants Adviser for The Wellcome Trust DBT India Alliance New Del-hi, India. She returned to research and joined Centre for Global Health, Institute of Population Health Sciences as Barts Charity Lecturer to establish an independent research group focused on host-pathogen interaction in tuberculosis. She now joins the Centre for Immunobiology, Blizard Institute.

Research

Research Interests:

Tuberculosis (TB) is a treatable bacterial infection caused by a bacterium, Mycobacterium tuberculosis(Mtb). Yet, it remains one of the leading causes of death in the developing nations around the world. The disease burden of TB remains high despite global efforts made by World Health organisation and United Nations. The increase in the prevalence of of drug resistant TB strains highlights the need of new and effective TB drugs.

My work at QMUL will focus on discovering novel drug targets pathways in Mtb with an aim to identify and evaluate targets that have a potential to alter Mtb host pathogen interaction and enhance host immune response towards Mtb infection.
