Research Experience

I have more than a decade of experience working with substance using and criminal justice populations in both domestic and international settings.  My overall research interests are on the overlap between addiction and behavioral health disorders, infectious diseases and criminal justice involvement.  I have focused my research on understanding risk for HIV acquisition and transmission among substance using and criminal justice populations as well as access to HIV and substance use treatment post-release from incarceration.  My research seeks to inform evidence based policy with respect to ameliorating the adverse consequences associated with substance use, which include incarceration and excess morbidity and mortality.
