Meet the TRIP Team

Faculty

Vani Simmons, PhD - Director
Senior Member

Vani Simmons, PhD is the 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.

Jennifer I. Vidrine, PhD
Senior Member

Jennifer I. Vidrine, PhD is the assistant center director for Research Community Partnerships and a senior member in the Department of Health Outcomes and Behavior. 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 including cancer survivors. A
prominent focus of her recent projects is on the use of mHealth approaches to efficiently and effectively deliver smoking cessation treatments. Dr. Vidrine's research program has been continuously supported by grants from the National Cancer Institute, Centers for Disease Control and Prevention, Center for Medicare and Medicaid Services, the Cancer Prevention Research Institute of Texas and the Florida Biomedical James and Esther King Research Program

Damon Vidrine, DrPH
Senior Member

Damon J. Vidrine, DrPH, is chair of the Department of Health Outcomes and Behavior. 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 
Assistant Member

Dr. Vinci received her PhD in Clinical Psychology from Louisiana State University. Her research focuses on developing and testing behavioral interventions that address cancer-risk behaviors (e.g., tobacco, alcohol use) and stress management. To date, most of the interventional research she has conducted is specific to mindfulness-based interventions and strategies, with a primary focus on mHealth and underserved populations.

Thomas Brandon, PhD  
Senior Member

Thomas Brandon, PhD is a 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.

David Drobes, PhD 
Senior Member Emeritus

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).

Research Staff

Cherell Cottrell-Daniels, PhD

Dr. Cherell Cottrell-Daniels is an Applied Postdoctoral Fellow at the Tobacco Research and Intervention Program in the Department of Health Outcomes and Behavior. She received her PhD in Public Health with a concentration in Health Promotion and Behavior from Georgia State University, School of Public Health. Her professional and research experience has centered on health disparities among low-income and underserved populations in urban and rural settings. During her doctoral training, she focused on addressing tobacco health disparities among low-income and African American smokers. She also held roles in NIH-funded clinical trials that utilized mHealth as a modality for intervention delivery. Building upon her previous training, Dr. Cottrell-Daniels is particularly interested in utilizing mixed methods to understand stressors and protective factors related to marijuana and tobacco co-use among priority populations (i.e., low-income, African Americans). Her work aims to promote tobacco cessation; eliminate tobacco-related cancer health disparities among priority populations; and to develop culturally relevant interventions.

Min-Jeong Yang, PhD

Dr. Yang received her PhD in Clinical Psychology in 2020 from Rutgers University, The State University of New Jersey. Dr. Yang’s research interests are primarily in promoting health behaviors in special populations with a focus on mindfulness- and exposure-based interventions for smoking cessation and relapse prevention. Since she joined Moffitt as a T32 behavioral oncology postdoctoral fellow under the mentorship of Drs. Christine Vinci and Vani Simmons at Tobacco Research and Intervention Program (TRIP), she has been working on multiple projects specific to smoking cessation treatments based on mindfulness and cue exposure, which utilize various research methodologies including ecological momentary assessment, wearable sensors, augmented reality, and low nicotine content cigarettes. She also has been leading multiple projects on the evaluation of the implementation of an e-referral system for smoking cessation at Moffitt and on the quality of life among sexual and gender minority cancer patients. Dr. Yang was recently awarded a K99 grant from the National Cancer Institute to develop an mHealth mindfulness-based smoking cessation intervention for cancer survivors.

Ranjita Poudel, PhD

Dr. Poudel is a T32 Behavioral Oncology fellow at the Tobacco Research and Intervention Program (TRIP) under the mentorship of Drs. Christine Vinci and Vani Simmons. She completed her PhD in Cognitive Neuroscience from Florida International University. Her primary research interest focuses on tailoring mindfulness and mHealth interventions for the treatment and prevention of cancer. She is currently involved in projects examining the efficacy of mindfulness in managing stress among cancer caregivers and the utility of mHealth to aid smoking cessation.
