I am a social and behavioral scientist in the field of public health. I study social processes across a number of behaviors that impact health, such as modern contraception use, intimate partner violence, Pre-Exposure Prophylaxis use, and tobacco consumption. My focus area is on the measurement, conceptualization, and influence of social norms across a variety of behavioral contexts. In particular, I am interested in the dynamics of social norms change, and how such changes manifest in multiple socioecological levels across diverse sociopolitical structures and institutions.
I focus on bridging behavior change theory with a range of rigorous quantitative statistical approaches. Methodologically, I am most interested in latent variable methods for longitudinal data (traditional SEMs and latent growth models), Bayesian regression (especially using informative priors), factor analysis, and meta-analysis.

Modeling change as a latent process, this study seeks to understand what the relationship between social norms and tobacco use change change is, over time, and what predicts the variation between individuals in this relationship. Several latent growth models are fit to answer research questions.
