Rahul Roychoudhuri studied Natural Sciences at the University of Cambridge and Clinical Medicine at King's College London. After completing Clinical Academic Foundation Training in Infectious Diseases at Guy's, King's and St. Thomas' Hospitals, Rahul moved to the United States where he undertook a Ph.D. in Gary Nabel's laboratory at the US National Institute of Allergy and Infectious Diseases (NIAID) identifying transcriptional heterogeneity within single immune cells responding to infection. Rahul then undertook a postdoctoral fellowship at Nicholas Restifo's laboratory at the US National Cancer Institute (NCI) where he continued his work on transcriptional regulation within the immune system. His work elucidated the critical functions of the transcriptional repressor BTB and CNC homology 2 (BACH2) in immunological tolerance and memory and defined novel mechanisms of immunosuppression within tumours. Rahul's group at the Babraham Institute is interested in understanding molecular and cellular mechanisms of tolerance and immunosuppression.
