Dr. Andrew James received bachelor degrees in Chemistry and Applied Psychology from the Georgia Institute of Technology. His graduate studies introduced him to functional neuroimaging, which perfectly fit his dual interests in analytical spectroscopy and human cognition. He received his doctorate in Neuroscience from the University of Florida, where he used functional MRI to model age-related changes in networks governing motor learning. In 2006, he accepted a postdoctoral fellowship with Dr. Xiaoping Hu of Emory University, where he pursued a variety of methodologically challenging neuroimaging projects such as taste perception of artificial sweeteners, motor network reorganization following stroke, and modeling individual differences in depressed patients’ emotion-regulating networks. In 2009, Dr. James joined the Department of Psychiatry and Behavioral Sciences in the College of Medicine at the University of Arkansas for Medical Sciences (UAMS). As an assistant professor in the Brain Imaging Research Center (BIRC), he is establishing the Cognitive Connectome to explore how the brain’s neural networks encode individual variability in personality and cognition.
Research Interests – By understanding how the healthy brain encodes cognition, he seeks to translate this technology into patient care and better inform clinical decision making. Dr. James believes that understanding individual differences in the neural encoding of traits such as craving, impulsivity, and working memory is crucial for understanding how these brain-behavior relationships are disrupted with addiction.
