Dr Tongyu Ma received his bachelor’s and master’s medical degrees from Tianjin Medical University and Peking University, respectively, followed by two years of residency training at Heping Hospital of Changzhi Medical University. Due to a strong interest in exercise and healthy lifestyles, Dr Ma studied exercise sciences at Arizona State University and obtained a PhD degree. Upon graduation, he started teaching undergraduate courses at Franklin Pierce University in New Hampshire as an assistant professor.

Dr Ma's current research focuses on the association between the timing of physical activity and mortality outcomes. He is interested in investigating the joint association of physical activity volume and timing with health outcomes, such as quality of life, general health, and risk of chronic diseases, including cardiovascular disease obesity, and diabetes. The combination of epidemiological approaches and cutting-edge machine lineaging algorithms allows him to deepen his current understanding of the association between physical activity and health benefits. His recent studies employed the NHANES and UK Biobank datasets. His future research will emphasize the optimization of physical activity patterns of Hong Kong people to provide practical recommendations for physical activity promotion.
