Dr. Hammond is an Assistant Professor of Psychiatry at Johns Hopkins University Department of Psychiatry with a joint appointment in the Division of Child & Adolescent Psychiatry and Behavioral Sciences and the Behavioral Pharmacology Research Unit (Affiliate). He completed his M.D. at University of Florida and his Ph.D. and residency/fellowship training at Yale University. Dr. Hammond’s research program focuses on characterizing the neurobiological predictors and mechanisms of treatment response for adolescent substance use disorders (SUDs) using multimodal neuroimaging (MRI, EEG) and large-scale brain network analytic approaches.  His research is funded by a NIDA/AACAP Career Development Award (K12DA000357). Dr. Hammond’s research group is embedded in a larger collaborative research network within Johns Hopkin University School of Medicine applying translational neuroscience, clinical, and epidemiological methods to improve our understanding of brain-behavior relationships for youth suffering from substance use and mental health problems and aid in designing better evidence-based interventions.  Clinically, Dr. Hammond works with youth (ages 13-25) with co-occurring substance use and psychiatric disorders in his role as Medical Director of the Co-occurring Disorders in Adolescents and Young Adults (CODA) Clinic at Johns Hopkins. He currently serves on the AACAP’s Substance Abuse and Addictions Committee and the American Academy of Addiction Psychiatry’s Youth and Adolescent Addiction Treatment Committee. more
