Ravindra Gupta

Ravindra Kumar Gupta (born 20 September 1975) is a professor of clinical microbiology at the Cambridge Institute of Therapeutic Immunology and Infectious Disease at the University of Cambridge. He is also a member of the faculty of the Africa Health Research Institute in Durban, South Africa.

Gupta was named in Times 100 Most Influential People in 2020.

Education Gupta attended Brentwood School from 1987 to 1994. Gupta gained his undergraduate medical degree from Cambridge University in 1997 and then clinical degree from Oxford University in 2001, whilst completing a Master in Public Health at Harvard School of Public Health (1998-1999). He subsequently trained in infectious diseases in Oxford and The Hospital for Tropical Diseases (UCLH) and completed a PhD in Virology with Deenan Pillay and Greg Towers at UCL. He was elected to Fellowship of the Academy of Medical Sciences in 2021 and to Fellowship of the Royal Society of Biologists in 2022.

Career Gupta researches HIV, from basic science of how the virus interacts with human cells and the immune system to the emerging problem of drug resistant HIV. More recently he has worked on COVID-19 rapid diagnostics, SARS-CoV-2 intra host evolution, replication, cell tropism and entry, as well as evasion from B cell immunity.

Gupta was formerly Full Professor at University College London (2016-2019). He is head of the Gupta Lab and was supported by Wellcome Trust Fellowships from 2007 to 2023.

Gupta's HIV-1 work spans the UK and sub Saharan Africa. The lab focuses on four main areas: HIV drug resistance and implications for global scale up of antiretroviral therapy. Dissecting the biology of macrophage-virus interactions and the role of cell cycle given myeloid cells are parasitised by HIV and are a difficult-to-treat reservoir. After a bone marrow transplant from an HIV-resistant donor, the London Patient remained "cured" of his HIV. This is the second case of a patient cured of HIV (Gupta et al, Nature 2019, Gupta et al, Lancet HIV 2020). The first patient is referred to as the Berlin Patient.

Gupta's group reported the first evidence for immune escape and infectivity enhancement of SARS-CoV-2 within host, thus also defining the process by which new variants likely arise in immune compromised individuals (Kemp et al, Nature 2021). Follow up work defined the replication advantages of Alpha (Meng et al, Cell Reports 2021) and Delta variants with efficient ability to fuse cells (Mlcochova et al, Nature 2021), and the tropism shift and immune escape of Omicron (Meng et al, Nature 2022). These observations have translated to the clinic, reflecting disease severity of Delta versus Omicron and critically aiding public health policy regarding newly emerging variants at global scale. His work on COVID-19 vaccine induced immunity in older and immune suppressed persons has also been internationally recognised.
