Rahul Roychoudhuri studied Clinical Medicine and Natural Sciences at the University of Cambridge. After completing the Clinical Academic Foundation Training Programme in Infectious Diseases at Guy's, King's and St. Thomas' Hospitals and King's College London, Rahul moved to the United States where he undertook a Ph.D. in Dr Gary Nabel's laboratory at the US National Institute of Allergy and Infectious Diseases at the National Institutes of Health (NIH) studying transcriptional heterogeneity within single immune cells responding to infection. Rahul undertook a postdoctoral fellowship at Dr Nicholas Restifo's laboratory at the US National Cancer Institute (NCI) where he continued his work on transcriptional regulation within the immune system. His research elucidated the critical functions of the transcriptional repressor BTB and CNC homology 2 (BACH2) in immunological tolerance and memory, defined novel mechanisms governing lineage specification within the T cell lineage, and identified factors within the microenvironment of tumours that promote immunosuppression.
Rahul's group at the Babraham Institute is interested in understanding molecular and cellular mechanisms of tolerance and immunosuppression. In 2015 Rahul was jointly awarded a Sir Henry Dale Fellowship by the Wellcome Trust and The Royal Society and in 2017 Rahul was awarded a Lister Institute Research Prize.
