I am Emeritus Professor of Psychological Services Research at the University of Sheffield and have worked in the NHS for many years in clinical services, training, senior management and policymaking. I developed my skills in CAT after editing Tony Ryle’s 1990 book ‘Cognitive Analytic Therapy: Active Participation in Change’ for Wiley. I have a longstanding interest in the effective application of research to practice and have led or contributed to a number of Department of Health policy initiatives in psychological therapies. In addition to individual psychotherapy, I am an experienced organisational consultant and management mentor.
