Stephen May is currently a Senior Lecturer in Physiotherapy at Sheffield Hallam University. A respected and extensively published practitioner, Stephen is a Fellow of the Chartered Society of Physiotherapists. He joined Sheffield Hallam in 2002 with 12 years of clinical experience gained working as a physiotherapist with Chesterfield PCT. Whilst there he helped expand the physiotherapy service into primary care, introduced evidence-based guidelines and routine use of outcome measures, created an orthopaedic screening service, and conducted audits and research.

Stephen later specialised in the McKenzie approach of mechanical diagnosis and therapy and continues his involvement with McKenzie Institute International. He also co-authored Robin McKenzie's textbooks on this approach to musculoskeletal problems.

His current research is focused on aspects of musculoskeletal physiotherapy, especially relating to mechanical diagnosis and therapy. In particular, Stephen's current work includes reliability studies on the use of mechanical diagnosis and therapy in extremity musculoskeletal problems.

Stephen is particularly interested in supporting students' transition into post-graduate study, encouraging students to gain the most from their studies, in preparation for their future careers saying "It has been great to see students progressing through the M.Sc. and then supervising their dissertations when they put all they learned into practice in real-world settings."
