OverviewAI-generated summary

G. Andrew James' research investigates neurocognitive mechanisms, particularly in the context of self-regulation, addiction, and mental health. He has served as Principal Investigator on two NIH/National Institute on Drug Abuse grants totaling $899,077. The first, for $394,051, focuses on sex-specific roles and neural processing correlates of future outcome estimation in the drug addiction process. The second grant, awarded $505,026, examines neurocognitive mechanisms underlying smartphone-assisted prevention of relapse in opioid use disorder.

His scholarly work includes publications on the role of the dorsal anterior cingulate cortex in performance monitoring during affect self-regulation, and neural activity related to value estimation and fear conditioning predicting posttraumatic stress disorder symptom severity. Recent publications also explore the functional link between myelination integrity and information processing speed in multiple sclerosis, as well as population-level age effects on white matter structure and cognitive flexibility. James' work also encompasses systematic reviews and meta-analyses of neuroimaging correlates of psychological resilience.

With an h-index of 6 and 20 total publications, James collaborates with colleagues at the University of Arkansas for Medical Sciences, including Maegan Calvert, Tatiana Wolfe, and Clint Kilts, with whom he shares multiple publications. He maintains an active lab website.
