Overview

Suzanne Colby, Ph.D. is a Professor (Research) of Psychiatry and Human Behavior and of Behavioral and Social Sciences at Brown University. A nationally recognized expert in adolescent tobacco research, Dr. Colby has participated in collaborative efforts to enhance research on and development of cessation treatments for adolescent smokers. She currently serves as President of the international Society for Research on Nicotine and Tobacco (SRNT), following previous SRNT roles as Member Delegate for North America, Chair of the Publications Committee, Program Chair, and Founding Chair of the Adolescent Research Network.

Dr. Colby is MPI of two research studies involving adolescent smokers. The first, with MPI Dr. Jennifer Tidey, is a Tobacco Center of Regulatory Science (U54DA031659, PIs Donny & Hatsukami) Research Component, is a laboratory-based study of the effects of nicotine content in cigarettes and nicotine concentration and flavors in e-cigarettes on responses to these products in adolescent smokers.  The second is supported by an R01 grant from NIDA (DA047356; Cassidy/Colby) that is examining the effects of cigarette nicotine reduction on potential substitution of alternative combusted and non-combusted tobacco use among adolescent smokers.

Dr. Colby also collaborates as a Co-Investigator on several other NIH research grants including: a randomized clinical trial (RCT) testing the efficacy of a culturally-adapted motivational intervention for Latinx heavy drinkers (PI: C.S. Lee); a recently completed computerized and text-based intervention with youth aging out of foster care (PI: J. Braciszewski); and studies testing smoking interventions for adults in substance abuse treatment; and a therapeutic process trial evaluating the hypothesized mechanisms that account for the effects of brief MI versus culturally adapted MI in Latinx heavy drinkers.  Dr. Colby participates in the leadership of the Brown Alcohol Research Center on HIV (ARCH), directing the pilot projects component and training initiatives for the ARCH.
