Our research focuses at the nexus of HIV and alcohol and other substance use. We examine epidemiological aspects of HIV and alcohol use/other drug use among persons with HIV (PWH), and work on the adaptation and testing of person and computer-delivered interventions for unhealthy alcohol use, particularly among women.
The James Potter Lab studies the effect of ethanol and its metabolites on the a2(I) and a1(I) collagen promoters; the role of leptin on fibrogenesis; the role of Kupffer cells, cytokines, retinoic acid and leptin in stellate cell tansdifferentiation and collagen production; hormonal regulation of rat class I alcohol dehydrogenase; and transcriptional regulation of rat class I alcohol dehydrogenase promotor.
Our lab evaluates new medications and/or techniques for the treatment of drug use disorder by conducting human laboratory studies to sensitively assess drug effects, and randomized controlled trial evaluations of medications for clinical treatment outcomes. We also focus on the development of outcome measures that are sensitive and clinically relevant.
The neuroimaging and Modulation Laboratory (NIMLAB) investigates neural correlates of cognition and behavior using neuroimaging methods such as functional magnetic resonance imaging (fMRI) and neuromodulation techniques such as transcranial magnetic stimulation (TMS).
We are looking in depth at the contributions of the cerebellum and cerebro-cerebellar circuits to cognition; the effects of chronic heavy alcohol consumption on cognition and brain activation underlying cognitive function; how aging in humans affects neural systems that are important for associative learning and stimulus awareness; and the integration of transcranial magnetic stimulation with functional MRI.
