 Nasir Uddin



Nasir joined the University of Essex as a Lecturer in Physiology in 2023 as part of the School of Rehabilitation and Exercise Science, with a specific research focus in neurophysiology. He is completing his PhD in Sports Medicine, investigating the neurophysiological responses of mild traumatic brain injuries and hypohydration. He is also a visiting researcher at the University of Oxford, as part of the Physiological Neuroimaging Group (PING), and the University of Essex representative for The Physiological Society. He has previously worked as a Clinical Research Practitioner at Queen Mary University London & NHS Barts Health, and as a Lecturer in Exercise Physiology and Biomechanics at London Metropolitan University, and City & Islington College. In addition to this, Nasir has previously worked as a Sports Scientist and coach for various professional organisations such as London Wasps RFC, Crystal Palace FC, British Weightlifting and the London Youth Games. His own sporting background is in freestyle wrestling and olympic weightlifitng, and he is a keen enthusiast of various combat sports.
