Shayan Aryannezhad
MD, MPH
Clinical Research Fellow
Shayan joined the Clinical Trial Service Unit and Epidemiological Studies Unit (CTSU) in January 2025 as a clinical research fellow. He is currently working on the ASCEND-PLUS trial, a phase IV randomised placebo-controlled trial which is designed to investigate the effect of adding oral semaglutide therapy to standard care in individuals with type 2 diabetes mellitus on cardiovascular events and other complications of diabetes.
Shayan is in the final stages of his PhD studies at the MRC Epidemiology Unit, University of Cambridge. His PhD research focuses on the epidemiology and public health aspects of cardiometabolic diseases. In particular, his work explores the role of diet and physical activity and their longitudinal changes in this context, using observational studies based on population-based prospective cohorts.
Prior to this, he completed his Doctor of Medicine (MD) and Master of Public Health (MPH) degrees in Tehran, Iran, graduating in 2021. During this time, he was actively involved in epidemiological research on obesity and the role of bariatric surgery in its treatment.
