Profile

Dr. Pankaj Sharma is a Scientist at the National Centre for Cell Science (NCCS), Pune, since January 2025. He obtained his Ph.D. from CSIR-Central Drug Research Institute, Lucknow, in 2017, followed by postdoctoral research at Boston Children's Hospital, Harvard Medical School (2017–2024). His research focuses on immunology, with an emphasis on B cell biology and cancer immunology. His laboratory investigates the molecular mechanisms regulating B cell receptor signaling within germinal centers (GCs), with the objective of informing rational vaccine design. Additionally, his lab is interested in understanding the age-dependent regulation of germinal centers and deciphering the role of stromal cells in shaping GC dynamics. In the domain of cancer immunology, his research aims to elucidate tumor-mediated suppression of antigen presentation pathways in dendritic cells, with a broader goal of developing strategies to counteract immune evasion.

Current Focus Areas

  • Understanding the mechanisms regulating selection of antibodies in health and disease.
