Professional Interests:

Schizophrenia and comorbid substance use disorder: neuropharmacology, neuroimaging and treatment development
Medication development for addiction
Brain reward circuitry
Animal models
Early intervention in schizophrenia

Dr. Green's research program, which involves clinical and neurobiological studies of patients with schizophrenia, particularly those with co-occurring substance use disorders, medication development studies for patients with alcoholism, and studies of alcohol drinking animals, has been funded by a series of grants from NIH, NARSAD and industry. He and his colleagues have proposed a neurobiological model suggesting that co-occurring substance use disorder in patients with schizophrenia relates, at least in part, to deficiencies in dopamine-mediated brain reward circuits. Data from his group have suggested that the novel antipsychotic medication clozapine limits alcohol and other substance use in these patients; he has proposed that the unique effects of clozapine in these patients relates to the mechanism of action of the drug, including its effects in brain reward circuits. On-going studies are continuing to probe the optimal psychopharmacological strategies for patients with co-occurring disorders through clinical trials, neuroimaging studies in humans, and a series of pharmacologic, neuroimaging and neurostimulation investigations in animals.

Rotations and Thesis Projects:

1) Medication development for alcohol drinking in rodents.
2) Neuroimaging and brain reward circuitry in schizophrenia.

R21DA044501 (Green) 09/01/2017 – 08/31/2019
Reward circuit dysfunction, substance use disorder, and schizophrenia: a preclinical fMRI-based connectivity study
The goal of this proposal is to begin to bridge the gap between clinical studies and our theoretical formulation of the basis of substance use in schizophrenia through study of fMRI connectivity in the NVHL rat.

R01DA034699 ( Green) 09/01/2013 – 03/31/2020
Cannabis, schizophrenia and reward: self-medication and agonist treatment?
Using neuroimaging techniques, as well as behavioral measures of reward responsiveness, this study aims to assess the effects of smoked cannabis and oral dronabinol (THC) on the brain reward circuit in patients with schizophrenia and co-occurring cannabis use disorder, as well as in patients with cannabis use disorder alone.

NIH/NIDA (via NIH Common Fund)
Applying Novel Technologies and Methods to Inform the Ontology of Self-Regulation
This study will examine putative targets (processes) of behavior change within the self-regulation mechanism domain across contexts, populations, and assays – in 3 primary levels of analysis: (1) psychological (e.g., constructs such as self-efficacy; emotion regulation; response inhibition), (2) behavioral (e.g., tasks of reward responsiveness; temporal horizon), and (3) biological (structural and functional MRI of key neural circuitry).
Role: Co-investigator

Alan I. Green, M.D. is the Raymond Sobel Professor of Psychiatry, Professor of Molecular and Systems Biology, and Chairman of the Department of Psychiatry at Geisel School of Medicine at Dartmouth.
Director, Dartmouth SYNERGY, The Dartmouth Clinical and Translational Science Institute.

He received his B.A. from Columbia College and his M.D. degree from the Johns Hopkins University School of Medicine. Following an internship in medicine at the Beth Israel Hospital in Boston, he was a research associate at the National Institute of Mental Health and was Director of Biomedical Research at the Special Action Office for Drug Abuse Prevention in the Executive Office of the President. He did his psychiatry residency and a clinical research fellowship at the Harvard-based Massachusetts Mental Health Center. He joined the Harvard faculty in 1984 and was Director of the Commonwealth Research Center at Harvard Medical School from 1987 until 2002. He joined the Geisel School of Medicine's Department of Psychiatry as Professor and Chairman in November 2002, and he became Director of Dartmouth SYNERGY in 2012. He has been a highly productive and active investigator, has received peer-reviewed funding throughout his career, has mentored over 45 trainees, and is the author of more than 300 papers and abstracts.

Mentoring Information:

Dr. Green has been the primary research mentor for over 45 predoctoral and postdoctoral trainees. At present, he is the primary mentor for a number of junior investigators, post-doctoral research fellows, graduate students, and undergraduates.
