OverviewAI-generated summary

G. Andrew James' research focuses on neuroimaging, particularly magnetic resonance imaging (MRI), to investigate brain function and its relationship to various psychological and neurological conditions. His work examines neural signatures associated with fear acquisition and extinction learning, especially in women with posttraumatic stress disorder (PTSD). James has studied the role of specific genetic variations, such as FAAH, in influencing these neural processes and their cognitive and physiological correlates.

His research also extends to understanding the neurocircuitry involved in self-regulation of affect and performance monitoring, with publications exploring action-value processing and the dorsal anterior cingulate cortex. Furthermore, James contributes to the study of neurological conditions like multiple sclerosis, conducting systematic reviews and meta-analyses on neuroimaging predictors of disability and cognitive outcomes. He also investigates the potential of technology-assisted interventions, such as smartphone applications, for optimizing treatment outcomes in substance use disorders, including opioid use disorder.

With an h-index of 26 and over 4,000 citations from 89 publications, James has secured significant federal funding from the NIH/National Institute on Drug Abuse. He has served as Principal Investigator on grants totaling over $895,000 to study sex-specific roles in outcome estimation in drug addiction and neurocognitive mechanisms for relapse prevention in opioid use disorder. He maintains collaborations with researchers at the University of Arkansas for Medical Sciences and actively manages a laboratory website.
