About The Program

Research Faculty Career Goals. UNTHSC is committed to nurturing PhD students whose career goals are positions as research faculty members at Tier I institutions. Our program includes intensive expectations in contributing to ongoing research projects, the establishment of publications, and academic conference presenting.

Full-time. Students take 9 hours each semester. The program carries a heavy research and publication expectation as well as professional development hours. Students serve as teaching assistants at least once a year. Employment outside the university is prohibited.

On-campus. UNTHSC is located in Fort Worth, Texas. A vibrant location within the Dallas-Fort Worth metroplex. Take advantage of our excellent city centers and low cost of living.

3-5 Year Program. Students are expected to complete the program in 3 to 5 years depending on their standing upon entrance. Students with completed MS degrees aligning with Ph.D. concentration will have the quickest path to completion, MPH students will have some additional Master's level work to complete and students entering following a Bachelor's degree will require 5 years to complete the program.

Fall Entrance. New students begin the program each Fall semester. There are no Spring or Summer start options.

Small PhD cohort. Current admission trends indicate a small admitted class of just 2-4 students in each discipline, allowing for an intense and personalized experience.

Faculty Mentors

When considering your Ph.D. institution, it's important to ensure a strong match with one or more mentor faculty members.

Matches at HSC are based on research topics or by research methodology. This means candidates who are interested in a research topic that isn’t currently represented in our faculty may identify a mentor based on their research methods. This will allow for a broader range of research topics on our campus, better reflecting the broad scope of public health work. Below are brief descriptions of current faculty research areas. We encourage you to review the full biographies of those most likely to serve as matches for your field.

  • Dr. Tracey Barnett:

    Dr. Barnett’s work focuses on risk behaviors across the lifespan. Her primary area includes adolescent and young adult risk behaviors, focused on substance use including but not limited to alternative tobacco, tobacco, alcohol and marijuana. Her secondary area includes the role of tobacco with adult cancers, including tobacco cessation programs. This research has included mixed methods, qualitative interviews, and focus groups, web-based surveys, and secondary data analysis.

  • Dr. Stacey Griner:

    Dr. Griner’s work focuses broadly on maternal and child health, sexual health, oral health, and evidence-based guidelines. She utilizes mixed methods, which includes survey-based research, secondary data analyses, interviews, and focus groups. Her work is guided by health behavior theories and implementation science frameworks to translate research into practice.

  • Dr. Ubydul Haque:

    Dr. Haque studies the transmission of infectious disease in an international context. More specifically, he examines the risk factors and the spatial spread of arbovirus transmission using modern computational tools and statistical techniques. Recently he has been using similar approaches to investigate and determine the risk factors and the spatial spread of COVID-19. 

  • Dr. Nolan Kline:

    Dr. Kline’s research focuses on the social and political determinants of health and health equity.  His work is informed by qualitative, community-based participatory research methods and social theories focused on structural inequality. His current research focuses on 1) the health-related consequences of immigration enforcement policies and 2) intersectional LGBTQ+ Latinx social movements to advance social justice and health equity.

  • Dr. Dana Litt:

    Dr. Litt studies the etiology and prevention of adolescent and young adult risk behavior, including substance use. Her research utilizes a variety of research methods including cross-sectional, longitudinal, experimental, and mixed-methods designs.  She also develops and tests brief interactive online and text-messaging interventions seeking to reduce risk-taking among adolescents and young adults.

  • Dr. Melissa Lewis:

    Dr. Lewis’ theory-driven research focuses on the etiology and prevention of health-risk behaviors. Across her portfolio of research, she has incorporated complex study designs using web-based surveys via phones to assess behavior and cognitions multiple times a day, and behavior change interventions testing web-conferencing and text message content.   

  • Dr. Justin Luningham:

    Dr. Luningham’s research focuses on developing quantitative methods that make sense of complex behavioral data. His recent work utilizes computational statistics, machine learning approaches, and latent variable models to study the genetics of mental health disorders. He also has extensive experience modeling and evaluating multivariate survey/questionnaire data, analyzing longitudinal data, and synthesizing data across multiple datasets. Substantively, he is interested in mental and behavioral health outcomes across the lifespan."

  • Dr. Eun-Young Mun:

    Dr. Mun meta-analyzes and synthesizes data from clinical trials to examine the comparative effectiveness of competing treatment strategies and delineate mechanisms of behavior change. She utilizes latent variable modeling, generalized linear mixed-effects modeling, Bayesian modeling, and statistical machine learning for data integration, classification and prediction, estimation, and causal inference to advance alcohol clinical trials, mHealth interventions, and clinical neuroscience.

  • Dr. Rajesh Nandy:

    Dr. Nandy studies the use of novel statistical methods and machine learning techniques to solve complex problems in the clinical diagnosis of neurological disorders. Specifically, his research methods focus on the use of neuroimaging data and various blood biomarkers towards the early diagnosis of conditions such as Alzheimer’s disease and Parkinson’s disease.
