My graduate and postdoctoral training were in the areas of psychological services, developmental psychology, poverty, and public policy with mentors whose backgrounds were in psychology, sociology, and economics. Thus, I have been trained across several social science disciplines, and consequently, I do not identify with one particular discipline. The majority of my interdisciplinary research program is centered around family-related factors, such as poverty and family structure, and their influence on food insecurity/food assistance program participation (i.e. indicators of poverty) and obesity; however, I also realize that nutrition and health do not occur in isolation. For that reason, I have also focused on stress, social support, depression, and cardiovascular health.
My target populations are socio-economically disadvantaged and vulnerable groups with a specific emphasis on racial and ethnic minorities, women, and children. To conduct my research I have primarily used longitudinal secondary data, but I have recently begun a complementary focus on community-engaged research. My interdisciplinary focus has provided me the opportunity to make significant contributions to various disciplines, including child development, family, and public health.
