Research Fellow


Liam Humphreys is a Research Fellow with over 7 years' experience of working in the fitness industry, research and consultancy. Liam's main area of interest is the role of exercise in the prevention and treatment of chronic disease.


Liam completed his BSc (hons) from Leeds Metropolitan University in 2006,which led him to pursue further study, achieving MSc Physical Activity for Health from Sheffield Hallam University. Liam began his research and consultancy career working on the SHU Wellness service; an award winning workplace health programme.

He has developed his professional skills through intervention design and the management of research using a variety of methods including; pilot studies, large randomised controlled trials, systematic reviews, qualitative research, and public health evaluations.

Liam's specific areas of interest are the role of physical activity in the prevention and management of chronic disease, and health behaviour change, specialising in motivational interviewing.

As a Research Fellow, Liam's role involves the design and management of several exercise-related research studies for patients with multiple sclerosis (MS), cardiovascular disease, intermittent claudication and cancer. Liam's latest work has focused on the design of innovative physical activity interventions for the management and rehabilitation of multiple sclerosis and the design and implementation of a physical activity referral scheme for people affected by cancer.

Liam's professional qualifications include; advanced (level 3) fitness instructor and level three award In Exercise Programming with Disabled People (IFI), American College of Sports Medicine (ACSM) Health Fitness Specialist and Cancer Exercise Specialist.
