Research Summary

My research is aimed at: (1) developing and evaluating treatments for patients with co-occurring opioid addiction (e.g., prescription opiates, heroin) and chronic pain (i.e., physical pain lasting at least 3 months); (2) examining the role of sociocultural factors in the occurrence and treatment of addictions (e.g., eating disorders, gambling, substance-related disorders).
