I am interested broadly in the relationship between social differences and individual differences, and between social advantage and embodied advantage. This includes work differences in physical health, cognitive functioning, health behaviors, and the role of differential utilization of knowledge and innovations toward producing differences. I am co-leader of the Health Disparities Working Group for the Stanford Center for Population Health Sciences.
I am part of ongoing efforts to better integrate biological and social science thinking. I have worked on how behavioral and molecular genetic information can be used to complement and elaborate our understanding of the consequences of social environments. I have also done work on the application of evolutionary biological reasoning to human behavior and social arrangements.
