Leadership:

Igor Grant, M.D., F.R.C.P. (C)Director
Igor Grant, M.D., is Distinguished Professor in the Department of Psychiatry at the University of California, San Diego School of Medicine. Since 2000, Dr. Grant has been Director of the State of California funded Center for Medicinal Cannabis Research (CMCR). He is also the Director of the HIV Neurobehavioral Research Program (HNRP), which encompasses a broad range of interdisciplinary HIV studies including the California NeuroAIDS Tissue Network (CNTN), the Translational Methamphetamine AIDS Research Center (TMARC), the HIV Neurobehavioral Research Center (HNRC), and the CNS HIV Antiretroviral Therapy Effects Research (CHARTER). Dr. Grant is the founding Editor of the Journal of the International Neuropsychological Society and founding co-editor of the journal AIDS and Behavior.
   
Thomas D. Marcotte, Ph.D. - Co-Director, Professor of Psychiatry
Dr. Marcotte, CMCR Co-Director, is a Professor of Psychiatry and neuropsychologist who has been affiliated with the CMCR since its inception. His primary focus has been on the impact of cannabis use on cognition and driving. This includes simulator and on-road studies, as well as the development of methods for determining cannabis-related impairment, including evaluating approaches used by law enforcement. He has served on national and state impaired-driving workgroups and presented to scientific, law enforcement, forensic toxicologist, judicial, and traffic safety advocacy groups, as well as state/national/international policymakers. His work has also explored medicinal applications of cannabis (pain, spasticity). Dr. Marcotte is lead editor of the book Neuropsychology of Everyday Functioning
   
J. Hampton Atkinson, M.D. - Co-Director, Professor Emeritus of Psychiatry
J. H. Atkinson, M.D., is Active Emeritus Professor in the Department of Psychiatry at the University of California, San Diego School of Medicine. Dr. Atkinson has been Co-Director of the State of California funded Center for Medicinal Cannabis Research (CMCR) since its inception in 2000. He was a prior Co-Director of the HIV Neurobehavioral Research Program (HNRP), which encompasses a broad range of interdisciplinary HIV studies. His research has investigated the pharmacological and cognitive behavioral treatment of chronic pain syndromes, principally chronic low back pain, and on neuropsychiatric aspects of HIV.
   
David Grelotti, M.D. – Medical Director, Clinical Professor of Psychiatry
Dr. Grelotti is a Professor of Psychiatry at UC San Diego and the Medical Director of the Center for Medicinal Cannabis Research (CMCR). He provides medical oversight to several clinical trials of cannabis and cannabinoids at the CMCR and provides mental health care and addiction treatment at UC San Diego's Owen Clinic. He also serves as the Scientific and Program Chair for CMCR's annual symposium.
   
Robert L. Fitzgerald, Ph.D., DABCC - Director CMCR Analytical Laboratory, Professor of Pathology
Robert Fitzgerald, Ph.D. is the director of the CMCR bioanalytical laboratory which uses isotope dilution liquid chromatography combined with mass spectrometry to quantify various cannabiniods and related metabolites in biological fluids. A focus of his research has been to help elucidate how toxicological testing can be used in combination with field sobriety tests to improve methods for identifying drivers under the influence of cannabis.
   
Jeremiah Momper, PharmD - CMCR Reference Laboratory Director, Professor of Pharmacy 
Jeremiah Momper, PharmD, PhD is a Professor in the Skaggs School of Pharmacy and Pharmaceutical Sciences at UC San Diego. Since 2020 Dr. Momper has directed the CMCR Reference Laboratory which serves as the California Department of Cannabis Control's reference laboratory by conducting testing of cannabis goods. Dr. Momper’s research program also focuses on the application of clinical pharmacology tools – including model-based approaches – to address emerging public health issues for cannabinoids, including exposure-response relationships for impaired driving, environmental hazards of cannabis smoke, and pharmacokinetics in children, older adults, and lactating women.
   
Raymond Suhandynata, Ph.D., DABCC, NRCC (CC), ASCP (C) – Associate Director - CMCR Reference Laboratory; Associate Director of Clinical Toxicology and Chemistry UCSD Health; Assistant Professor of Pathology and Pharmacy
Since 2021, Dr. Suhandynata has served as the Associate Director of the CMCR Reference Laboratory, which serves as the reference laboratory for the California Department of Cannabis Control by conducting testing of cannabis goods. Dr. Suhandynata's research is focused on the development and validation of laboratory developed tests (LDTs) in the clinical laboratory, development of mass spectrometry based approaches to detect antibiotic resistant bacteria, identification of novel psychoactive substances, development of new approaches to measure biologics/proteins in clinical specimens, and development of LC-MS/MS assays for the measurement of cannabinoids, drugs of abuse, and therapeutic drug monitoring.
Jamie Corroon, N.D., M.P.H. - Assistant Project Scientist in Psychiatry
Jamie Corroon, ND, MPH, is a licensed Naturopathic Doctor and Assistant Project Scientist at the Center for Medicinal Cannabis Research (CMCR) in the Department of Psychiatry at the University of California, San Diego (UCSD). He completed a postdoctoral fellowship in the Department of Family Medicine at UCSD, funded by a T32 grant from the National Heart, Lung, and Blood Institute. His work examines the impact of cannabis use on cardiovascular health, as well as the broader clinical and public health implications of society’s increasing acceptance of cannabis. Dr. Corroon earned a bachelor’s degree in Political Science from the University of Southern California, a master’s degree in Public Health (Epidemiology) from San Diego State University, and a Doctor of Naturopathic Medicine degree from Bastyr University.
