Katherine-MacLean-July2015Katherine MacLean, PhD. is the Director of the Psychedelic Education and Continuing Care Program and a trained research scientist with a long-standing interest in the brain and the science of well-being. At the University of California, Davis, Katherine was supported by a NSF research fellowship to study the effects of mindfulness on well-being and brain function. As a postdoctoral research fellow and faculty member at the Johns Hopkins University School of Medicine, she worked with Dr. Roland Griffiths and his team. Her research on psilocybin and personality change suggests that this class of medicines may play an important role in enhancing mental health, promoting emotional well-being, and creativity throughout the lifespan. Her current focus is the role of psychedelics and meditation in preparing individuals for end-of-life and healing trauma related to grief. Email:
