 Sarah E. Messiah, PhD, MPH, FTOS Professor and Director
|
Dr. Messiah is the inaugural director of the Center for Pediatric Population Health and a tenured Professor of Epidemiology, Human Genetics & Environmental Sciences at UTHealth School of Public Health. She is a perinatal/pediatric and life course epidemiologist whose research focuses on childhood obesity and cardiometabolic disease risk factors and the implementation of evidence-based practices into clinical and community-based settings to improve health outcomes. |
 Andrea C. Betts, PhD, MPH Assistant Professor
|
Dr. Betts' cancer control research endeavors to enhance healthcare accessibility and the overall well-being of marginalized communities, with a special focus on individuals who have survived cancer during their adolescent and young adult years (AYAs). Her primary interest lies in the creation and execution of interventions grounded in empirical evidence, with the goal of enhancing the healthcare experiences and results for AYAs. |
 Alejandra Fernandez, PhD Assistant Professor
|
Dr. Fernandez’s research generally focuses on the health of Hispanic adolescents and their families. Her research is centered around improving family functioning between Hispanic adolescents and their family members in order to prevent and reduce adverse health outcomes, including substance use behaviors, sexual risk behaviors, adverse mental health outcomes, and obesity related outcomes. The mechanism primarily used in Dr. Fernandez’s research to improve health outcomes is the development and testing of family-based interventions. |
 Serwaa S. Omowale, PhD, LMSW, MPH Assistant Professor
|
Dr. Omowale's research is centered on examining how employment functions as a social determinant of health and its influence on racial disparities observed in maternal health and birth outcomes. Additionally, she is dedicated to the creation of interventions that are culturally sensitive, aiming to mitigate negative pregnancy outcomes among Black women. Dr. Omowale employs a range of research approaches to craft interventions tailored to specific populations, ensuring cultural appropriateness. Her ultimate goal is to address and eliminate health disparities in areas such as maternal mortality, infant mortality, and preterm birth outcomes, ultimately striving for health equity. |
 Jenil Patel, MBBS, MPH, PhD Assistant Professor
|
Dr. Patel conduct research on congenital heart defects, along with designing new studies to create optimal occupational exposure assessment techniques in order to draw implications to reduce overall burden of birth defects. Additionally, he also works on conducting new epidemiological studies to identify environmental and occupational risk factors for pediatric asthma in North Texas. |
 Kevin C. Rix, Jr, PhD, MPH Assistant Professor
|
Dr. Rix's research interests are primarily centered on injury and violence prevention, the application of implementation science principles to injury and violence prevention initiatives, and the field of injury epidemiology. Dr. Rix's research approach is strongly rooted in practical experience, as he dedicated seven years to managing an injury and violence prevention program at a level one trauma center in Austin, TX. During his tenure at the hospital, he served as a mentor for numerous UTHealth students who were completing their practicum experiences in injury prevention. His research primarily delves into the correlation between space-time factors and the risk of injury across various injury mechanisms. |
 Andrea Ramirez Varela, MD, PhD, MPH Assistant Professor
|
Dr. Varela is a physician-scientist who specializes in the intersection of public health, physical activity epidemiology, and health policy research. Her career focuses on three areas: conducting studies among underserved populations in low and middle-income countries, establishing global surveillance systems for physical activity and policy, and using a syndemic approach to understand the link between physical activity promotion, non-communicable disease prevention, and infectious disease crises (such as COVID19). Dr. Varela holds a joint appointment in the Department of Pediatrics at UTHealth Houston McGovern Medical School. |
 Luyu (Amber) Xie, PhD, PharmD Assistant Professor
|
Dr. Xie received her PharmD in 2017 from University of Nebraska Medical Center and her PhD from UTHealth Houston School of Public Health in 2022. Her ongoing research mainly focuses on 1) population-based, pharmacoepidemiological studies in asthma; 2) epidemiological research on the health outcome and behaviors of pediatric patients diagnosed with COVID-19; and 3) genetic risk factors detection using Mendelian Randomization. Dr. Xie is also collaborating with multiple research teams from the Parkland Center for Clinical Innovation, Departments of Internal Medicine and Obstetrics and Gynecology at The University of Texas Southwestern Medical Center. She has co-authored over 30 manuscripts in peer reviewed journals and has presented her research at various national and international meetings. Dr. Xie has received the Women in Science and Medicine Advisory Committee Travel Award for outstanding poster presentation at UT Southwestern. She is also the recipient of the Denton A.
