Dr Tom Withers BSc(Hons), MSc, PhD

Dr Tom Withers

School of Sport, Exercise and Rehabilitation Sciences
Research Fellow

Dr Tom Withers research interests center around the utilisation of physical activity as a method to improve both mental and physical health, particularly in individuals with chronic illness or mobility impairment.


PhD - Physical Activity and Total Hip Replacement - University of East Anglia
MSc - Clinical Exercise Physiology - Liverpool John Moores University
BSc (Hons) - Exercise and Sport Sciences - University of Exeter 


Tom undertook his undergraduate and taught postgraduate studies at the University of Exeter and Liverpool John Moores University. Following a brief research post at Swansea University working on the development of an implantable artificial lung he undertook his PhD at the University of East Anglia. Tom’s PhD focused on the initial phases of developing an intervention to promote physical activity in the hip replacement population. This was followed by a working on a project promoting physical activity in people with spinal cord injury. He then took up his current Research Fellow post at the University of Birmingham which has a focus on physical activity promotion in hard to reach populations.

Postgraduate supervision

Tom is currently able to supervise new research students. You should send him an email in the first instance if you would like to discuss this further.
