Nick is a Chartered Physiotherapist and Certified Strength and Conditioning Specialist, and a Senior Lecturer in Sport Rehabilitation at St Mary’s University. Nick has more than 15 years of clinical experience in the U.K. including work at the Royal Free Hospital NHS Trust, Guy’s & St Thomas’ NHS Foundation Trust, Saracens Rugby Union Football Club, and private practice. He has also worked for the British Army, including being a Clinical Specialist with the Parachute Regiment and a Consultant Physiotherapist redesigning the Physiotherapy Outpatients service for the Infantry and Armoured Regiments. His higher education experience includes undergraduate and post-graduate lecturing and external examining at several universities in the U.K. and U.S. including University College London, King’s College London, Middlesex University, and the University of Pittsburgh.
Nick’s research experience also extends over 15 years and includes studies in sports medicine and military contexts. In sports medicine, Nick’s area of expertise is the knee with an emphasis on anterior cruciate ligament (ACL) injury prevention and rehabilitation. In a military context, he has been involved in injury prevention and performance optimisation research with U.S. Special Operations Forces. Nick is Manuscript Reviewer for Physical Therapy in Sport, The Knee, the International Journal of Sports Physical Therapy, the Journal of Sport Rehabilitation, and Manual Therapy. He has also been invited to fulfil roles as a Research Grant Reviewer for the Physiotherapy Research Foundation, a Visiting Lecturer to the American College of Sports Medicine (ACSM), and a Clinical Supervisor and Clinical Examiner for the Musculoskeletal Association of Chartered Physiotherapists (MACP).
