Professor John Harrison

I am a specialist in occupational medicine with an established track record of practising in healthcare, with a particular interest in the health of doctors. I am now embarking on a new phase of my career as I set out on a new journey to use my experience and leadership experience with the police. I occupy a number of leadership positions and am committed to establishing the discipline of occupational health to promote the health and prosperity of working age people within a global market place.

I am actively working to develop an occupational health workforce that is equiped to take advantage of the changing healthcare and business economies. This will require new ways of thinking and new ways of working. I have a longstanding interest in and commitment to occupational medicine education and intend to its profile, quality and national status to complement other changes in the leadership and quality assurance of training. Strengthening the UK academic base in occupational health will be an essential component of this.
