Bhargavi is at present working at Médecins Sans Frontières (MSF/Doctors without Borders) as a Malaria and Infectious Diseases specialist whilst completing her training in Public Health. She graduated in 1999 from Oxford University (Cambridge pre-clinical) and did her post-graduate medical training in London interspersed with international clinical and research interludes in Peru, India and other countries.

Bhargavi then went to do a Masters in Public Health (International Health) at Harvard in 2004 and following that joined Harvard Medical School as a Faculty Instructor in HIV/AIDS and Infectious Diseases. As part of this, she was posted to South Africa for three years where she helped to run an HIV/AIDS treatment NGO which included training South African doctors to manage HIV in primary and secondary care. She returned to the UK and made the switch to Public Health training with a focus on global health.

Bhargavi was awarded a Wellcome Trust research training fellowship for her PhD modelling the impact of health systems on malaria transmission, based jointly at Imperial College, the London School of Hygiene and Tropical Medicine and the Ifakara Health Institute (Tanzania). After completing her PhD she joined MSF initially as a public health specialist, including missions to South Sudan, Bangladesh, Central African Republic and Democratic Republic of Congo.

In her current role as Malaria and Infectious Diseases specialist, she is responsible not only for overseeing programmes, directing relevant research and training of medical staff, but is also working to set up a Diploma in Tropical Medicine course within the organisation. Bhargavi has been teaching on the Ealing PACES course since 2003.
