I am a Professor in the Department of Psychiatry at the Medical University of South Carolina (MUSC), and a Staff Psychologist at the Ralph H. Johnson Veterans Affairs Medical Center. I have been actively involved in clinical research for the past 16 years, with a focus on the treatment of substance use disorders and posttraumatic stress disorder. I am currently PI of a 5-year NIDA-funded randomized clinical trial investigating an integrated cognitive behavioral treatment for substance use disorders and co-occurring PTSD among military Veterans (R01 DA030143). I am Co-I on several other federally-funded patient-oriented studies focused on the treatment of substance use disorders with or without comorbid PTSD. I was the past PI of (1) a 5-year NIDA-funded study examining the relationship between reactivity to laboratory-induced stress and conditioned drug cues among individuals with prescription opiate dependence, as well as rats trained to administered heroin (K23 DA021228); and (2) a 4-year National Research Service Award that investigated cocaine dependence and co-occurring PTSD (F31 DA00607). In addition, I am Director of the MUSC Drug Abuse Research Training (DART) resident research track, and the DART Summer Research Fellowship program for undergraduate, graduate and medical students at MUSC.
