Jim Grigsby is a faculty member in the CU Denver Psychology Department, where he teaches cognitive neuroscience/neuropsychology and supervises research for graduate students in the clinical health psychology doctoral program. Occasionally he writes biosketches about himself in the third person. Grigsby also has a part-time appointment in the CU Denver School of Medicine, Department of Medicine, Division of Health Care Policy and Research, where he was a research scientist from 1992 until he came to the Psychology Department in 2008. He was a co-discoverer of the Fragile X-Associated Tremor/Ataxia Syndrome, which he has studied for over 20 years. Grigsby has an active research lab in which he works with both graduate and undergraduate students. In recent years, his primary interests have been in cognitive neuroscience, especially executive functioning, FXTAS, the gut-brain axis, and the psychotherapeutic uses and mechanism of psychedelic drugs and 3,4- methylenedioxymethamphetamine (MDMA). He has had funding from NIH (NIA,NINDS, and NIDCD) and several other federal, state, and private agencies and organizations, including the Centers for Medicare and Medicaid Services (CMS), Health Resources and Services Administration (HRSA), Department of Defense (DOD), Office for the Advancement of Telehealth (OAT), and the Robert Wood Johnson Foundation.
