My program of research takes place at the intersection of social epidemiology and environmental health with the aim of reducing physical and mental health disparities. Areas of particular interest include the food environment and climate.

The Food Environment

Access to adequate healthy food is a basic human right. Unfortunately, food insecurity is a problem worldwide that disproportionately affects historically undeserved racial/ethnic groups. Research is needed to inform strategies that reduce food insecurity and its impact on health outcomes like depression and diabetes.


Air quality, temperature, sunlight and extreme weather events influence health. Vulnerability is determined by geographic location, and the ability for communities and individuals to adapt to climate change. More research is needed to understand underlying biological mechanisms and inform tailored interventions.
