Dr. Gregg Henriques is associate professor of psychology at James Madison University and Director of JMU’s Combined-Integrated Doctoral Program in Clinical and School Psychology.
Dr. Henriques’ teaches unified psychotherapy, personality and personality assessment and psychopathology. His primary areas of interest are in the theoretical unification of psychology and the promotion of a unified psychotherapy.
Most importantly, he has developed a new scientific humanistic philosophy called the Tree of Knowledge System, which he argues can unite the key insights of the various paradigms into a more coherence whole.
Dr. Henriques has published his ideas in several prominent journals, and special issues of the Journal of Clinical Psychology and Theory and Psychology have been devoted to presenting and critiquing the system. He is currently involved on a book project, A New Unified Theory of Psychology, that spells out his vision in greater detail.
He received his BA in Psychology from JMU, his M.A. in Clinical/Community Psychology from the University of North Carolina-Charlotte, his Ph.D. from the University of Vermont and post-doctoral training at the University of Pennsylvania. He joined the faculty at JMU in 2003 and was appointed director in 2005.
