Professor Jha studied Medicine at the University of Manitoba and was awarded a DPhil in Epidemiology and Public Health at the University of Oxford, where he was supervised by the late Professor Dame Valerie Beral and Professor Sir Richard Peto. He is currently the University Professor of Global Health and Epidemiology at the Dalla Lana School of Public Health and Temerity School of Medicine, University of Toronto, and Director of the Centre for Global Health Research, Unity Health Toronto. He has served on a number of advisory boards and has been a health adviser to several governments.

Professor Jha said:

‘It is a unique privilege to succeed Professor Sir Rory Collins as Head of the Nuffield Department of Population Health. The department is internationally renowned for providing definitive evidence on some of the most important health-related questions, and for pioneering new methods that have changed the way population research is undertaken. I look forward to working with the department’s multidisciplinary teams to continue to improve the health of millions of people and prevent avoidable suffering around the world.’

Professor Jha’s research focuses on large-scale epidemiological studies of the major causes of death in developing countries (including tobacco, alcohol, cardiometabolic risk factors, and air pollution), and epidemiological research methods in low-resource settings, including randomised intervention studies. He is also particularly interested in the use of routine mortality data for analytic epidemiology, and tobacco control policy in developed and developing countries. His research enabled a worldwide treaty on tobacco control signed now by 180 countries. He has quantified malaria mortality in children and adults in various settings, leading to vaccine trials.

Professor Lady Sue Black, President of St John’s, said:

‘We look forward to welcoming Professor Jha to the vibrant academic community at St John's and wish him every success in continuing the groundbreaking research of the department.’

Professor Jha was appointed Officer of the Order of Canada in 2012 for his contributions to epidemiology and the economics of global health. He has received a number of other awards, including the 2022 Award of Excellence from the American Public Health Association and the 2012 American Cancer Society’s Luther L Terry Award for Outstanding Research Contribution for his globally influential research on tobacco control.
