Dr. Gregg Henriques (Full Professor) has been in the JMU C-I Clinical and School program since 2003. He became director of the program in 2005. In addition to providing administrative oversight of the program, he also engages in clinical supervision and teaches courses on social and personality psychology, integrative psychotherapy and history and systems. His primary area of interest is in the development of a new unified approach to psychology, about which he has published extensively. In 2011 he outlined his approach in a book, A New Unified Theory of Psychology, (Springer, 2011). For the past several years, he has authored a Psychology Today blog called Theory of Knowledge, which offers weekly blog posts on a wide variety of topics related to his view for a more unified field.

Dr. Henriques is currently utilizing his system to systematically study character and well-being, social motivation and emotion, and to develop a more unified approach to psychotherapy. Dr. Henriques also has expertise in the assessment and treatment of severe psychopathology, particularly depression and suicide. Dr. Henriques is currently a licensed clinical psychologist in Virginia. He is married to Andrea Henriques and they have three children, Sydney, Jon, and Lanie.
