Dr. Ribisl is chair and Jo Anne Earp Distinguished Professor in the Department of Health Behavior at the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill. Ribisl is also the program leader for Cancer Prevention and Control at UNC’s Lineberger Comprehensive Cancer Center. He served as a member of the congressionally-mandated Tobacco Products Scientific Advisory Committee (TPSAC) for the United States Food and Drug Administration Center for Tobacco Products from 2012 to 2016.Professor Ribisl’s primary research interest is evaluating and improving the reach of population-level efforts to reduce tobacco use with a particular emphasis on policy and information technology. He specializes in studying policy issues related to the sales and marketing of tobacco products at the point of sale and on the Internet. He has researched tobacco product marketing, pricing, promotions and youth access as well as use of geographic information systems in tobacco control.
Noel Brewer, PhD, Professor of Health Behavior, UNC Gillings School of Global Public Health
Dr. Brewer’s research explores why people engage in vaccination, vaping and other health behaviors that prevent cancer. He has published over 300 papers on these topics including behaviors related to HPV vaccination and vaping warnings. He was one of the most cited researchers in the world (top 1%) from 2017-2019. He has advised on vaccination for the World Health Organization, Centers for Disease Control and Prevention, the President’s Cancer Panel under two presidents, and the National Vaccine Advisory Committee.
Marissa Hall, PhD, Assistant Professor, Department of Health Behavior, UNC Gillings School of Global Public Health
Dr. Hall’s research focuses on health communication strategies and policy solutions that encourage people to make healthier choices and ultimately reduce the global burden of cancer and other chronic diseases. Her research program includes 1) designing and evaluating policies to reduce tobacco use, 2) designing and evaluating policies to prevent obesity, and 3) examining the impact of health policies on Latinx health disparities. Her research is currently supported by a K01 Career Development Award from NIH and grants from Robert Wood Johnson Foundation.
Nisha Gottfredson O’Shea, PhD, Research Public Health Analyst, Substance Use, Prevention, Evaluation & Research Program, RTI International
Dr. Gottfredson O’Shea extends and applies quantitative methods to study problems related to health and health behavior. Her primary interest is in the use of longitudinal data analysis techniques to study how developmental processes unfold over time with applications to substance use and dependence, eating behaviors and eating disorders, and other psychological and behavioral outcomes.
Erin Sutfin, PhD, Professor, Social Sciences and Health Policy, Wake Forest School of Medicine
Dr. Sutfin is a developmental psychologist with over 15 years of experience conducting NIH-funded research in tobacco prevention and control. She is also Associate Director of the Wake Forest Tobacco Control Center of Excellence and Co-Director of the Wake Forest Qualitative and Patient-Reported Outcomes Shared Resource. The goal of her program of study is to decrease morbidity and mortality related to tobacco use. Her expertise in adolescent and young adult tobacco prevention and control focuses on non-cigarette tobacco products, including waterpipe tobacco, electronic cigarettes, and cigar products. Her research aims to impact tobacco use through environmental interventions, including policy, health communication, and system-level changes.
Paschal Sheeran, PhD, Professor, Department of Psychology and Neuroscience, UNC College of Arts & Sciences, Adjunct Professor, Department of Health Behavior, UNC Gillings School of Global Public Health
Dr. Sheeran is a social psychologist whose research concerns self-regulation – how people direct their thoughts, feelings and actions to achieve their goals. His particular interests are health behavior change and emotion regulation with research on:
1) The intention-behavior ‘gap.’ His research shows that people successfully translate intentions into action only about 50 percent of the time, and pinpoints factors that determine consistencies between intentions and behavior.2) The use of implementation intentions to reduce the intention-behavior ‘gap’ and improve rates of performance of health behaviors.3) Using meta-analysis to assess how much change in health-related intentions and behavior accrues from interventions that change the key predictors specified by health behavior theories.4) His recent work has begun to examine nonconscious routes to action and the self-regulation of implicit influence.
Ilona Jaspers, PhD, Professor, Departments of Pediatrics, Microbiology & Immunology and Environmental Sciences and Engineering, Director of the Center for Environmental Medicine, Asthma, and Lung Biology, Director for the Curriculum in Toxicology and Environmental Medicine Training program
Dr. Jaspers is a professor with more than 20 years of experience at the University of North Carolina at Chapel Hill who specializes in the effects of ambient air pollutants and tobacco products on respiratory immune disfunction. She has established several human in vitro and clinical in vivo models to determine the adverse health effects induced by inhaled toxicant exposures. As the Director of the Center for Environmental Medicine, Asthma and Lung Biology, Jaspers collaborates extensively with investigators from UNC and the U.S. Environmental Protection agency to conduct translational studies related to air pollution health effects. She is also the director of the Curriculum in Toxicology, overseeing the training and mentoring of masters and doctoral students as well as postdoctoral fellows.
Sarah Kowitt, PhD, Assistant Professor, Department of Family Medicine, UNC School of Medicine
Dr. Kowitt’s research focuses on tobacco prevention and control and chronic disease management. Within those two fields, she is most interested in examining how policies and neighborhood characteristics affect behaviors and health outcomes, particularly among youth and young adults. She has published more than 45 peer-reviewed papers in journals including Health Affairs, PLoS One, Journal of Adolescent Health, Health & Place, Tobacco Control, and Nicotine and Tobacco Research. In 2020, she served as an expert panel member on a SAMSHA evidence-based guide on reducing youth and young adult vaping. Dr. Kowitt’s additional research interests include health communication, alcohol and tobacco co-use, and marijuana use.
Jennifer Cornacchione Ross, PhD, Associate Professor, Health Law, Policy & Management, Boston University
Jennifer Cornacchione Ross, PhD, is an Associate Professor in the Department of Health Law, Policy, and Management at Boston University School of Public Health. She is a communication scientist who uses persuasion and health communication theories and methods to develop and test effective messages to reduce tobacco use and understand message features that may influence beliefs, such as tobacco industry marketing. Much of her work is focused on tobacco policy and regulation among priority populations, including adolescents, young adults, and those identifying as Black or African American. Through her work, Dr. Ross seeks to reduce tobacco-related disparities and provide evidence for implementing equitable tobacco policies. She is PI/MPI for two R01 studies funded by the National Cancer Institute to optimize and test the effectiveness of warnings for cigarillos among young adults and adolescents. Dr. Ross earned her PhD in Communication from Michigan State University and completed a postdoctoral fellowship in tobacco regulatory science at Wake Forest University School of Medicine.
