Professor Ravindra Gupta is an AHRI faculty member and a professor of clinical microbiology at the Cambridge Institute for Therapeutic Immunology and Infectious Diseases. In 2020, Ravi was named as one of TIME’s 100 most influential people of 2020.
Ravi initially trained as a clinical infectious diseases physician and went on to do a PhD at University College London, where he examined the epidemiology and virology of HIV drug resistance in sub-Saharan Africa and the interplay between the restriction factor tetherin and the HIV gene Vpu. Most of his work since has focussed on antiviral therapy for treatment of HIV, and he has led a number of studies, both clinical and in vitro, aimed at addressing the global emerging threat of drug resistant HIV. His programme of work is informed by clinical work as an infectious diseases physician, through which he has been able to study unique individuals with HIV in order to better understand viral reservoirs and immune control of HIV.

The Gupta Group has teams at both Africa Health Research Institute in South Africa, and at the University of Cambridge in the UK. Prof Ravi Gupta has had continuous Wellcome funding as a Fellow since 2007, and most recently secured a Wellcome Senior Fellowship in 2016 to study the biological properties of drug resistant viruses in South Africa, including acquisition of increased replication fitness and cellular tropism changes as part of evolutionary adaptation to drug pressure. Africa Health Research Institute represents an ideal environment in which to study drug resistant HIV-1, given the large numbers of treated patients and the fact that 10% or more patients experience treatment failure. This project brings together the multiple strands of his ongoing research to address critically important consequences of global access to antiretroviral therapy. Future plans include work on the role of myeloid cells in HIV associated brain disease during antiretroviral therapy, paving the way to study drug resistant reservoirs in the brain.

Collaborating Research Fellow
Dami is a physician specialising in Infectious Diseases and a Wellcome Clinical PhD student at University College London. At AHRI Dami facilitates the HERB (HIV escape and resistance in the brain) study, which aims to investigate the occurrence of independent replication of HIV in the brain of South African patients with neurocognitive impairment and to study the evolution of drug resistance in these compartmentalised viruses.
