Research Interests
- Social and environmental determinants of health inequalities across the life course.
- Psychosocial stress, health behaviors, and biological pathways linking socioeconomic status to morbidity and mortality.
- Child growth, nutrition, and development in low- and middle-income countries.
- Evaluation of early childhood interventions and policies, including Head Start and related programs.
- Advanced quantitative methods, including multilevel modeling, causal inference, mediation analysis, and distributional approaches.
My work focuses on how social structures, policy environments, and psychosocial mechanisms shape population health. I use rigorous quantitative methods—ranging from multilevel and causal models to distributional and mediation approaches— to understand when and how social and economic conditions translate into disparities in chronic disease, mental health, and mortality. Much of my research centers on early life environments and childhood interventions, as well as the role of psychosocial stress and related behavioral and biological pathways in producing and sustaining health inequities.
