Biography
Since 2006, I have served as Chief Executive Officer of the APT Foundation, a non-profit agency founded in 1970 by members of the Yale University Department of Psychiatry to promote health and recovery for those who live with substance use disorders and/or mental illness. My professional interests focus on identifying treatment gaps in substance abuse/mental health treatment and improving access to those services including services for persons who are incarcerated or recently released from jail or prison.
My academic interests and pursuits include large- and small-scale implementation projects that are focused on access to and quality in mental health care and substance abuse treatment services including integration with primary care, and integration of treatment for infectious diseases such as HIV/AIDS and HCV. My role in these project teams is often as both coach and researcher. I currently hold a position as an assistant professor in the Yale School of Medicine AIDS program and as a faculty member in addiction medicine.

Overview
Since 2004, the focus of my work has been the relationship between improved access to care, particularly mental health, substance abuse and infectious diseases treatment, and the resultant improvements in both patient outcomes and financial performance. I have contributed to the refinement and theoretical understanding of the rapid cycle process improvement model as advanced by NIATX (www.NIATx.net) headquartered at the University of Wisconsin-Madison. I have used this model as both a coach and a researcher in working with individual organizations, state level learning collaboratives, and learning collaboratives composed of organizations throughout the US and in Ukraine. Specific contributions to science cluster in three areas: Improving Access to and Retention in Substance Abuse Treatment, Enhancing Integration Between Substance Abuse Treatment Services and Infectious Diseases, and
Developing Strategies for Systems and Clinicians to Respond Effectively to Complex Patients.
