Published manuscripts and book chapters focus on the use of adaptive stepped care, treatment incentives, and integrated treatment of co-occurring disorders in a single setting. Through his work at Johns Hopkins Health Care, he has developed a related focus on fostering policies and initiatives applied in managed care settings to improve health outcomes and control costs, such as increasing the identification and treatment of substance use disorder and coordinating treatment of general somatic, mental health, and substance use disorders.
