David Barnes’s training is in psychiatric epidemiology.  Using both quantitative and qualitative methods, his research currently focuses on substance abuse, its treatment, and transitions to and from injection drug use, particularly as these transitions influence HIV and HCV risk.  His prior research has examined mental and behavioral health outcomes in sexual and ethnic minorities, specifically examining how social stress processes influence these outcomes in both expected and paradoxical ways.  As a post-doc at the VA, he examined recent veterans’ mental and substance use health care and treatment utilization as functions of symptomatology and socio-economic factors.
