Profile

Biography

Nick joined the University of Essex in 2019. Previously, he worked as a Senior Lecturer in Physiotherapy and Sport Rehabilitation at St Mary's University Twickenham (2014-2019) where he also founded and led the Knee Injury Control and Clinical Advancement Research Group. To date, Nick has more than 23 years of clinical experience having worked as a Chartered Physiotherapist in the National Health Service, private practice, performing arts, elite rugby union, and the British Army (Infantry and Armoured Cavalry, Parachute Regiment). He specialised in the provision of rehabilitation for people with lower back, hip, knee, and ankle problems following traumatic injury, gradual-onset injury, surgery (bone, cartilage, ligament, joint replacement), ageing-associated osteoarthritis, and post-trauma osteoarthritis. In 2009, Nick undertook his Doctoral studies in the Neuromuscular Research Laboratory (NMRL) and Warrior Human Performance Research Center (WHPRC) at the University of Pittsburgh where he worked within the faculty's military Special Forces injury prevention and human performance enhancement programmes. Concurrently, he completed his PhD specifically in the area of sensorimotor control (proprioception, neuromuscular control) of knee functional joint stability and noncontact anterior cruciate ligament (ACL) injury prevention for agility-sport athletes. Currently, Nick's research and clinical areas of interest include knee and ankle injury prevention, injury rehabilitation, and post-trauma osteoarthritis control. He works with physically active populations including sports athletes (football, rugby, netball, basketball, field hockey), tactical athletes (Army, Navy, Air Force, Special Forces, police officers, firefighters), and in occupational health with workers with medium, heavy, and very heavy job demands. He is a member of the FireFit Steering Group, the multi-disciplinary official steering group for the health, fitness, and well-being of members of the United Kingdom's Fire and Rescue Services. Nick has been a qualified Gym Instructor and Fitness Trainer (free-weights, resistance machines, circuit training) through the United Kingdom YMCA since 1993 and a Certified Strength and Conditioning Specialist (CSCS) through the United States National Strength and Conditioning Association since 2000.
