Role
Dr Johnson is a Principal Lecturer in exercise physiology and teaches at undergraduate and postgraduate level. He is the Postgraduate Courses Manager for the MRes Sport Science courses and a Fellow of the Higher Education Academy.
Dr Johnson completed his PhD at Nottingham Trent University and his research activity is focused on respiratory and exercise physiology, specifically responses and limitations of the pulmonary system during exercise, mechanisms of dyspnoea/breathlessness, the aetiology of exercise intolerance, and exercise-induced asthma.
Research areas
Dr Johnson is a member of the Exercise & Health Research Group in the Sport, Health & Performance Enhancement (SHAPE) Research Centre. His research is primarily focused on respiratory and exercise physiology, specifically responses and limitations of the pulmonary system during exercise, mechanisms of dyspnoea/breathlessness, the aetiology of exercise intolerance, and exercise-induced asthma.
Dr Johnson has authored many peer-reviewed journal articles in these research areas and has presented his research at numerous internationally-renowned scientific conferences. He is a member of the European Respiratory Society and peer reviewer for numerous scientific journals.
Opportunities to carry out postgraduate research towards an MPhil/PhD exist and further information may be obtained from the NTU Graduate School.
