OverviewAI-generated summary

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

His recent publications explore various aspects of brain function and its relation to psychological states and disorders. These include studies on action-value processing in the dorsal anterior cingulate cortex for affect self-regulation, value estimation and latent-state updates in fear conditioning predicting PTSD severity, and neuroimaging correlates of psychological resilience through a systematic review and meta-analysis. Additional work examines the link between white matter integrity in the cingulum bundle and information processing speed in multiple sclerosis, as well as population-level age effects on white matter structure related to cognitive flexibility.

James collaborates with researchers at the University of Arkansas for Medical Sciences, including Maegan Calvert, Tatiana Wolfe, and Clint Kilts, and maintains an active lab website. His scholarly contributions are reflected in an h-index of 6, with 20 publications and 123 citations.
