Mala Maini is a Professor of Viral Immunology in the Institute of Infection, Immunity and Transplantation at UCL, London and an Honorary Consultant Physician in the viral hepatitis clinic. The Maini lab studies adaptive immunity to hepatitis B, liver cancer and SARS-CoV-2 to inform the development of immunotherapies and vaccines for these major causes of morbidity and mortality. Through access to well-characterised patient cohorts, human tissue samples and models, their studies provide insights into beneficial and dysfunctional T and B cell responses. The lab is particularly interested in dissecting and harnessing tissue-resident immunity for frontline sentinel surveillance of viruses and cancer. Mala enjoys mentoring and supporting her lab members to obtain fellowships and develop their careers. Work in the Maini lab is funded by Wellcome, UKRI, Cancer Research UK, ERC Horizon 2020 and the Royal Free Charity.
