TRI is an independent, non-profit research and development organization dedicated to science-driven transformation of addiction policy and treatment.

Co-founded in 1992 by A. Thomas McLellan, Ph.D., Jack Durell, M.D. and others from the University of Pennsylvania’s Center for the Studies of Addiction,TRI conducts original research and adapts scientific findings into products and services helping treatment providers, policy makers and parents.

In 2009, A. Thomas McLellan was named by the Obama/Biden Administration to be Deputy Director of the White House Office of National Drug Control Policy, bringing an emphasis on science and “effective” policies to the serious and cross-cutting challenges of addiction and unhealthy substance use in the nation.

The work of TRI continues through its Executive Director, Constance Pechura, Ph.D., and the investigators whose research, policy, and development expertise have put TRI in the forefront of many of the most important advances in the addiction field. More
