Meet the TRIP Team
Thomas Brandon, PhD - Director
Thomas Brandon, PhD, is the Director of the Tobacco Research and Intervention Program and Chair of the Department of Health Outcomes and Behavior at Moffitt Cancer Center. He is also Professor of Psychology and Oncologic Sciences at the University of South Florida. Dr. Brandon’s research focuses on factors that maintain tobacco dependence, as well as the development of novel tobacco-cessation and relapse-prevention interventions. His research has examined the problem of cigarette smoking and smoking relapse via several different modalities, ranging from basic human laboratory research on smoking motivation, through applied research on smoking cessation and relapse prevention across populations. With interventions, he has concentrated on theory-based behavioral treatments and self-help interventions. The Forever Free® self-help programs have been validated in four randomized controlled trials and are disseminated by NCI and health organizations nationwide. Recently, Dr. Brandon expanded his research to study addiction mechanisms and potential clinical utility of electronic cigarettes.
Vani Simmons, PhD - Co-Director
Vani Simmons, PhD, is the Co-Director of the Tobacco Research and Intervention Program. Dr. Simmons’ research interests include the development of smoking cessation and relapse-prevention interventions for special populations (at-risk/vulnerable groups) including cancer patients, college students, and ethnic minorities. Smoking among cancer patients can result in numerous adverse health consequences. Dr. Simmons and her team have developed a line of research to create a novel, theory-based smoking-relapse prevention intervention for cancer patients. Her work with cancer patients has recently extended to electronic cigarette use and to understanding barriers and facilitators to low-dose computed tomography as a screening tool for high-risk smokers. Dr. Simmons has also conducted research on the development of culturally appropriate smoking relapse-prevention and cessation intervention materials for Hispanic smokers and she is currently co-leading (with Dr. Brandon) a randomized controlled trial to test the efficacy of a Spanish-language self-help smoking cessation intervention for Hispanic smokers. Her research has been funded by the National Cancer Institute, Florida Department of Health James and Esther King Biomedical Research Program, and other foundations.
David Drobes, PhD
Dr. Drobes has conducted extensive human laboratory studies of cue reactivity and withdrawal among cigarette smokers, with a long-term goal to translate laboratory findings into novel behavioral and pharmacological smoking cessation treatments. Recent work has focused on effects of low nicotine cigarettes on smoking behavior and cessation. He has served as Principal Investigator on grants from federal, state, and private agencies. Dr. Drobes received his PhD in Clinical Psychology from Purdue University, followed by post-doctoral fellowships at the University of Florida (psychophysiology) and the Medical University of South Carolina (substance abuse).
Jennifer I. Vidrine, PhD
Jennifer I. Vidrine, PhD is Assistant Center Director for Research Strategic Partnerships at Moffitt Cancer Center and Senior Member in the Department of Health Outcomes and Behavior at Moffitt. Dr. Vidrine’s research program focuses on eliminating health disparities through evaluating the impact of tailored health risk communications, examining potential mechanisms underlying changes in risk perceptions over time in the natural environment, and evaluating both healthcare systems-level and community-based tobacco cessation interventions targeted to vulnerable and underserved populations. Her research program has been continuously supported over the past 16 years by grants from the National Cancer Institute, Centers for Disease Control and Prevention, Center for Medicare and Medicaid Services, and the Cancer Prevention Research Institute of Texas. She is currently leading two large NCI-funded projects. The first is evaluating the efficacy of a novel smoking cessation intervention for cervical cancer survivors. The second (a Multiple PI award with Dr. Damon Vidrine) is evaluating the efficacy of a fully mobile, theoretically-based smartphone-delivered smoking cessation intervention among smokers receiving services through food pantries within the Feeding Tampa Bay network.
Damon Vidrine, DrPH
Damon J. Vidrine, DrPH, is Vice Chair and Senior Member in the Department of Health Outcomes and Behavior at Moffitt Cancer Center. His research program is focused on tobacco use in special and underserved populations, including people living with HIV/AIDS, community-based socioeconomically disadvantaged populations, safety net clinic-based populations, and cancer patients. This work, which has been continuously funded since the time of his postdoctoral fellowship, has focused on the identification of the unique risks of tobacco use in these underserved populations, as well as the development and evaluation of novel cessation interventions. A common theme in Dr. Vidrine’s research program is the use of mobile devices (i.e., cell phones, tablet computers, and smartphones) for both behavioral assessment and intervention delivery purposes. The goal of these efforts is to develop and disseminate efficacious yet low burden treatments. This work has helped to establish the feasibility, acceptability, and efficacy of using mobile health (mHealth) approaches with underserved populations.
Christine Vinci, PhD
Dr. Vinci’s research broadly focuses on cognitive and effective mechanisms (e.g., affect, affect regulation, expectancies) implicated in the development, maintenance, and treatment of cancer-risk behaviors. More specifically, her work aims to understand the mechanisms underlying smoking cessation and decreased alcohol use among underserved populations in order to inform the development and modification of treatment interventions. She has a specific interest in mindfulness-based treatments, as these interventions have the ability to target mechanisms that are central to changing certain behaviors including quitting smoking and decreasing alcohol use. She currently has a K99/R00 award from the National Institute on Minority Health and Health Disparities that is utilizing advanced technology (i.e., ecological momentary assessment, human sensing) to examine the impact of mindfulness strategies sent via text message on key mechanisms underlying smoking cessation among a sample of low socioeconomic and racially/ethnically diverse smokers.
Karen Obremski Brandon, PhD
Karen Obremski Brandon, PhD, is a Research Scientist at the Tobacco Research and Intervention Program. Dr. Brandon received her PhD in Clinical Psychology from Indiana University. She focused on familial and individual difference characteristics of alcohol use and abuse in children, adolescents and adults before joining TRIP. She currently contributes to projects on self-help for smoking cessation, health disparities in smoking cessation treatments, and e-cigarette use for smoking cessation.
Ursula Martinez, PhD
Ursula Martinez, PhD, is an Applied Research Scientist at the Tobacco Research and Intervention Program (TRIP). Dr. Martinez received her PhD in Clinical Psychology from the University of Santiago de Compostela (Spain) in 2015, where she studied how psychopathology influenced the smoking cessation process in smokers receiving treatment. At the end of her predoctoral training, she received a grant fellowship to spend six months at the University of Newcastle (Australia) where she started working in the field of smoking cessation in the cancer patient population. During her postdoctoral fellowship, she is studying smoking cessation treatments in special populations, including cancer patients and Hispanics, and nicotine dependence in e-cigarette users. She completed her postdoctoral training in Behavioral Oncology at Moffitt Cancer Center. Her research interests include smoking cessation among special populations including cancer patients, e-cigarette users and Hispanics. She currently has an R03 award from the National Cancer Institute to create targeted interventions to increase motivation to quit smoking specifically for patients whose cancers are not generally considered to be smoking-related, but for whom smoking cessation is still necessary to improve cancer treatment outcomes.
