Melissa Harrell, PhD, MPH is a behavioral epidemiologist with 15 years of experience in the design, implementation, and analysis of large-scale intervention trials designed to promote child and adolescent health. Dr. Harrell completed her undergraduate studies at the College of William & Mary (1991) in Virginia and received her MPH (Community Health Education, 1999) and Ph.D. (Behavioral Epidemiology, 2002) from the School of Public Health at the University of Minnesota. Since 2006, she has served on the faculty with the University of Texas Health Science Center at Houston School of Public Health in Austin, with the Michael & Susan Dell Center for Healthy Living. She is an Associate Professor in Epidemiology.

Dr. Harrell has had a long standing interest in promoting youth health, particularly that of adolescents. She has been integrally involved in leading roles in a number of large-scale intervention trials for young people. These trials have addressed multiple issues relevant to adolescent health (e.g., tobacco, alcohol, HIV/AIDS, nutrition, and physical activity) and have been conducted in rural and urban settings in the US and in international settings like India and Uruguay. These trials have involved thousands of young people from diverse socio-economic backgrounds and have tested the effectiveness of an array of intervention strategies, from school-based curriculum to youth-led activism. Dr. Harrell was a Senior Editor of the 2012 US Surgeon General’s Report on Tobacco Use, which comprehensively reviews the science behind reducing tobacco use among youth globally. She currently serves as the Associate Director of the Texas Tobacco Center of Regulatory Science and leads one of its three research studies too.

In 2005, Dr. Harrell was named “Outstanding Young Prevention Scientist” by the Society for Prevention Research in the United States, and in 2009, she was awarded “Outstanding Young Investigator” for the UTHealth Science Center. She has over 70 peer-reviewed publications.

She currently serves as the Associate Director of the Texas Tobacco Center of Regulatory Science and leads one of its three research studies too. This research study focuses on tobacco use behaviors and the impact of tobacco marketing on them among middle school and high school youth in four large metropolitan areas of Texas (Houston, San Antonio, Dallas/Ft. Worth, Austin).  In 2016, Dr. Harrell also served as a Senior Associate Editor for the Surgeon General’s Report on E-cigarette Use among Young People, and led the production of the chapter on the epidemiology of e-cigarette use.

Additional Research Projects - Peers Against Tobacco: The goal of this study is to create a computer-based tobacco prevention and cessation intervention for college students in Texas.  This is one component of a multiple component project which will start with 16 colleges statewide and grow to cover many more in the state.
