Yuyin Zhou is a visiting student at the Oxford Institute of Population Ageing from September 2026 to March 2027. She is currently a PhD candidate in Demography at the Institute of Population Research, Peking University.

Her research interests include population health, sexual health, and HIV prevention. Her doctoral research focuses on promoting the use of HIV pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (GBMSM). Drawing on implementation science, she employs mixed methods to explore barriers to accessing preventive healthcare services, individual preferences, and strategies for improving service delivery.

During her visit to Oxford, she aims to further develop her research on HIV prevention and health behaviour interventions while broadening her understanding of sexual health across the life course. She is particularly interested in the intersection of ageing, sexual health, and equitable access to preventive healthcare services.
