The Training Program, with funding from the Oklahoma Tobacco Settlement Endowment Trust, offers training to undergraduate and graduate students as well as postdoctoral fellows in the area of tobacco-related research. The mission of the Program is to train the next generation of tobacco scientists to develop and conduct innovative and meaningful research and help end the burden of tobacco-related death and disease. The program offers diverse educational experiences and research opportunities under the mentorship of an experienced tobacco researcher.

Faculty mentors  participating in the Training Program all have NIH, ACS, or FDA-funded research grants examining diverse tobacco-related topics including:

  • Smoking Cessation with Underserved Populations
  • Tobacco Health Disparities and Comorbidities
  • Mobile Health Assessment and Interventions
  • Affective Neuroscience
  • Tobacco Biomarkers and Cancer Biology
  • Tobacco Regulatory Science and Policy
  • Healthcare Systems-Level Changes to Facilitate Tobacco Treatment Delivery
  • Smoking Health Risk Communications 
  • Laboratory Topography and Observation of Tobacco Use Behavior

The TSET HPRC Postdoctoral Training Program is a structured training experience consisting of didactic seminars, workshops on grant-writing and professional development led by TSET HPRC-core faculty, and a planned written candidate experience with the trainee’s faculty mentor. A Career Development Plan is completed annually, starting at the beginning of postdoctoral fellowship and revisited every 6-months (or annually, depending on the mentor’s preferred approach) to ensure progress is on track and postdoctoral professional development needs are being met.

The Career Development Plan is tailored to the individual needs and research interests of the fellow, and is completed in conjunction with the feedback and assistance of the primary mentor. There are five core criteria of the Career Development Plan: 1) Scholarly Activities, 2) Publication Plans and Activities, 3) Presentation Opportunities, 4) General Transferable Professional Development, and 5) Career Specific Professional Development. Additional faculty beyond the primary faculty mentor may be chosen to be part of the fellow’s Career Development Plan, in consultation with the primary mentor. This approach has been designed to foster working collaborations across departments and institutions and help expand the candidate’s exposure to a variety of professional mentors and colleagues. Faculty can be chosen from within TSET HPRC, or outside of the TSET HPRC.

The postdoctoral seminars occur monthly and topics are chosen at the beginning of each academic year (August/September), to align with the various interests and needs of the fellows. Feedback is obtained in a survey format prior to developing the schedule so that fellows have input as to the topics of greatest interest to them. Specific grant writing seminars are included in the structure of the training program. Graduate students and junior faculty from within TSET HPRC and other departments are invited to attend. Below is the schedule for the 2022 postdoctoral seminars.

She is passionate about global mental health, humanitarian health, social justice, and working with historically disadvantaged and displaced populations. Munjireen is interested in how digital health and mHealth can help foster mental well-being in these populations. Her dissertation topic focused on the mental health of Bangladeshi university students, and the acceptability of using a mindfulness App to promote mental health in that population.


Sarah Tonkin, PhD

Sarah started as a Postdoctoral Research Fellow at the HPRC in August 2022. Sarah earned her PhD in Clinical Psychology from The State University of New York at Buffalo. Dr. Tonkin's research seeks to identify psychological treatment mechanisms for smoking cessation and address treatment disparities by examining how these processes vary in populations that tend to benefit less from smoking interventions. To answer these questions, Sarah uses a translational approach that examines laboratory and “real-world” measurement of behavior, affect, and cognition. Her work at HPRC will integrate EMA, psychophysiology, and behavioral tasks to assess mechanisms and disparities.

Previous Postdoctoral Fellows

Sarah J. Ehlke, PhD

Dr. Sarah J. Ehlke is a postdoctoral research fellow at the Health Promotion Research Center at the Stephenson Cancer Center at the University of Oklahoma Health Sciences Center. Dr. Ehlke earned her doctoral degree in Health Psychology from Old Dominion University. Her research focuses on substance use, primarily alcohol and tobacco use, among sexual minority individuals.

Elise Stevens, PhD

Elise Stevens was at the HPRC from August 2016 – July 2019. She earned her PhD in mass communication with a focus on the psychological effects of health messages from the University of North Carolina at Chapel Hill. Dr. Stevens’ primary focus is on the cognitive, affective, and behavioral responses to health messages. Her research examines two areas of health communication: 1) identifying communication techniques and features that promote the use of unhealthy products (e.g., advertising of tobacco products) and 2) developing health messages aimed at decreasing risky health behaviors (e.g., anti-tobacco messages) to better understand how to inform tobacco product regulations and policies and encourage behavior change. She has since  received a K99/R00 Career Development Award from the National Institutes of Drug Abuse.  Dr. Stevens is an Assistant Professor at the University of Massachusetts Medical School in the Department of Population and Quantitative Health Sciences.




David Frank, PhD

David Frank started on January 9, 2017. He earned his PhD in Neuroscience at the University of Georgia focusing on the stability, timing, and connectivity of affective neural networks in the human brain. David is interested in the brain mechanisms that underlie emotional stimulus processing and how this affects attention and reward. Through the use of noninvasive measures including rapid sampling functional magnetic resonance imaging (fMRI), dense-array electroencephalography (EEG), and peripheral psychophysiological recording, he investigates the functions of cortical and subcortical networks that have evolved to facilitate appetitive and defensive behavior.





Bárbara Piñeiro, PhD

Barbara Piñeiro was a Postdoctoral Research Fellow under the mentorship of Dr. Jennifer I. Vidrine from May 2017 to June 2019.In this position, she expanded her knowledge and expertise in the area of tobacco-related health disparities.

Dr. Alayna P. Tackett earned her PhD from Oklahoma State University in 2017 and completed her clinical residency at the Alpert Medical School of Brown University. She completed her a postdoctoral research fellowship through a Ruth L. Kirschstein National Research Service Award (NRSA) Individual Postdoctoral Fellowship (National Heart, Lung, and Blood Institute (NHLBI); Award # F32HL138734) at Brown University and the TSET Health Promotion Research Center. Dr. Tackett’s postdoctoral research examined the respiratory and inflammation effects of electronic cigarette use in youth with asthma under the mentorship of Theodore Wagener, PhD, Elizabeth McQuaid, PhD, Deborah Pearlman, PhD, and Kate Guthrie, PhD. During this time, Dr. Tackett was awarded a Loan Repayment Grant Award from the NIH/NHLBI and a tobacco regulatory science K01 career development award (K01 HL148907) which will examine the longitudinal respiratory effects of e-cigarettes among youth and young adults using human laboratory methodology and ecological momentary assessment. Dr. Tackett is an Assistant Professor in the Department of Pediatrics at the University of Oklahoma Health Sciences Center (OUHSC)


Dr. Anh Ngo, PhD

Dr. Ngo earned her PhD in Economics from the University of Illinois at Chicago in August 2018. Her research interests focus on tobacco control policies and alcohol taxes. Applying innovative research designs, Dr. Ngo and her colleagues examined the impacts of tobacco control policies (i.e. point of sale advertising bans, graphic warning labels, MPOWER) on smoking prevalence and cigarette consumption in a global context. Her research has been published in leading public health journals such as AddictionPreventive Medicine, and International Journal of Environmental Research and Public Health. 

Currently, Dr. Ngo is extending her research to e-cigarettes and alcohol taxes. Specifically, using online discrete choice experiments, she and her colleagues are examining the impacts of flavors, device types, and health warning messages on the choice of e-cigarettes among US young adults. In the other projects, using time-series data of alcoholic beverage prices and taxes from Organization for Economic Cooperation and Development (OECD) countries, she and her co-authors estimate the excise tax pass through rates to prices of alcohol products to provide evidence on factors associated with alcohol tax avoidance and evasion in both US and international contexts.
