Research Interests
The ultimate goal of my research is to develop interventions to improve eating behaviors of all Americans. My research focuses on understanding, preventing, and correcting overeating behaviors in the early family unit. I rely on quantitative, qualitative, and mixed methods to answer my research questions. Measures I most commonly use to assess variables of interest are reliable and validated self-report, observational, and anthropometric in nature.
