Research and/or Creative Works

My research interests are two-fold. I have conducted research focused on the development and evaluation of novel treatments for opioid misuse and use disorder. Most recently, this has included work on two randomized clinical trials evaluating a novel interim buprenorphine treatment for reducing illicit opioid use and other high-risk behaviors among adults with untreated opioid use disorder. I also have a research interest focused on the delivery and evaluation of cognitive-behavioral treatments for posttraumatic stress disorder in individuals with concurrent substance use disorders. I am currently preparing to integrate these two areas of research as I direct a study investigating the contribution of prolonged exposure therapy, an efficacious manualized cognitive-behavioral treatment for posttraumatic stress disorder, above and beyond opioid agonist treatment alone for reducing posttraumatic stress disorder symptoms among patients with concurrent posttraumatic stress disorder and opioid use disorder.
