Dr. Ranjit’s research interests span two broad areas: social and behavioral epidemiology, and design and evaluation of behavioral interventions. Her work in social and behavioral epidemiology includes several highly cited studies examining environmental, socioeconomic, racial /ethnic, psychosocial factors and behavioral factors associated with disparities in a variety of population health outcomes, including chronic disease biomarkers, health risk behaviors, obesity, and mortality. Her second broad area of research, the design and evaluation of behavioral interventions, is focused on detailed evaluation of effectiveness of interventions, by decomposing the effects of multi-component interventions, and identifying why some subpopulations and some behavioral outcomes appear especially susceptible to the effect of particular interventions. In both areas of research, her work is informed by an explicit focus on quantitative methodologies and an examination of mechanisms underlying social disparities in health.
Currently, she is PI of the SNAP-Ed Evaluation project, a project to implement effective evaluation practices across all SNAP-Ed implementing Agencies in Texas, and Co-PI of “A Prescription for Healthy Living”, a project to evaluate effectiveness of a currently ongoing Produce Prescription program conducted by the Houston Food Bank. Other projects include a state-wide school surveillance project of obesity and its behavioral correlates; an evaluation of a sexual education program used for high school students; and a healthy food retail initiative. Dr. Ranjit has also served as Director of the Data Core, an initiative designed to support and maintain a high level of excellence and productivity in research activity at the Center. In this capacity, she provides research guidance to doctoral and post-doctoral students in Austin. She also regularly teaches doctoral level courses on Research Design and Analysis, and Program Evaluation.
The Central Texas CATCH Middle School Project (CATCH MS) was a school-based health promotion initiative aimed at promoting physical activity, healthy eating and obesity prevention among middle school students living in central Texas.
Texas SNAP-Ed Evaluation, is a two-year project to evaluate, on a statewide basis, the effectiveness of SNAP-Ed nutrition education and obesity prevention programming activities delivered by Implementing Agencies throughout the state of Texas.
This project is a collaborative effort that will study the impact of two recent policies: the Safe Routes to School program and an important rule revision to the federal food allocation package administered by the Texas Women, Infants and Children program.
