Michael joined Thompson Dunn as a Consultant Psychologist in October 2012. His interest in the psychology of business was sparked during his undergraduate Psychology MA at the University of Edinburgh. He then moved to London to work towards an MSc in Organisational Psychology at City University, which he achieved with Distinction.

Michael’s interests range from coaching, leadership development and assessment, to the overlap between occupational and sporting psychological principles. This overlap was the motivation for his thesis research that explored the work-recovery experiences of professional cricketers, and the resulting practical and health implications for individual sporting professionals and regulatory bodies.

As a Senior Consultant Psychologist, Michael has developed an extensive portfolio of international client work during his time with Thompson Dunn - specialising in executive recruitment assessment, leadership development and coaching. He works very closely with Managing Director and Principal Psychologist Pat Thompson to deliver in depth developmental and recruitment assessment work on behalf of clients around the world. As of June 2018, Michael became a Director of Thompson Dunn Ltd.

In addition to his work as a Psychologist, Michael has been a major driving force behind the development and production of the Decision Profile. His input has seen the instrument grow and to become a world class assessment tool available to licensed clients, globally. He is a Director of Decision Profile Ltd. and offers unique coaching services to help businesses to understand and develop their decision making culture and talent.

Michael is a graduate member of the British Psychological Society and is working towards his Chartership in Occupational Psychology.
