Area of Specialization:

Nutritional epidemiology and food systems



Dr. Conrad’s research utilizes large datasets and modeling techniques to examine the complex interactions between food choice, diet quality, and environmental sustainability. Specifically, his research focuses on how population-level dietary changes affect health outcomes, natural resource use, and sustainable food production, with an emphasis on low-income and other nutritionally vulnerable populations.
