Purnima Bhat is a Senior Research Fellow at the ANU Medical School. She is a practicing clinical Gastroenterologist with appointments at Canberra Hospital, and at Canberra Gastoenterology. Purnima obtained her medical degree at the University of Queensland and specialised in Gastroenterology and Liver Transplantation at the Austin Hospital, Melbourne. She received her PhD from the University of Melbourne for research on Hepatitis B Virus at the Burnet Institute.

Purnima's research interests focus on mucosal immunology in the gut. Her lab works in translational medicine with a view to the development of novel therapies for diseases such as cancer, inflammatory bowel disease, and viral hepatitis. Her laboratory has developed in vitro and animal models for the examining the gut immune system and applies these methods to investigate the behaviour of diseases in patients.

Purnima is a member of the World Endoscopy Organisation African Outreach Committee which promotes gastroenterology teaching and research in Africa. WEO has now developed and supported several new centres including flagship endoscopy sites in Nairobi and Addis Ababa. https://www.worldendo.org/
