Reena Rajasuriar is an Associate Professor at the Department of Medicine, University of Malaya, and an adjunct Research Fellow at the Peter Doherty Institute for Infection and Immunity, Melbourne University, Australia. She graduated with a Bachelor of Pharmacy (Hons) and a Master’s in Clinical Pharmacy from University of Science Malaysia. She worked as a pharmacist and junior faculty at the Department of Pharmacy, University of Malaya, prior to obtaining her PhD in immunology at Monash University, Australia. Her doctoral research was focused on immunogenetics and immune activation in HIV. She returned to Malaysia to establish the core immunology research facility at the Faculty of Medicine, University of Malaya, which she currently heads. 

Dr Rajasuriar coordinates the translational research programme in HIV immunology and ageing at the Centre of Excellence for Research in AIDS (CERiA) at the University of Malaya. Her research focuses on understanding the immunopathogenesis of aging in people living with HIV and other disease models of accelerated aging, namely childhood cancer survivors. In collaboration with her colleagues, she established the Malaysian HIV and Aging (MHIVA) cohort to study the phenotype of aging and associated risk factors among people living with HIV in low- and middle-income settings. Dr Rajasuriar’s work is guided by the hypothesis that the process of aging is more accurately captured by functional versus chronological age and that studying both social factors and mechanistic/biologic drivers is important in informing our understanding of this process.
