Human Development Initiative

HDI Logo

The Human Development Initiative, begun in 2009, is a community of scholars throughout the university interested in development across the lifespan. The initiative creates venues where scholars involved in cutting-edge research in the social and health sciences (including genetics, neuroscience, and psychosocial development) can focus on the intersections between their own work and that of other researchers. We invite faculty and graduate students to join us at our bi-weekly brown bag speaker series and our fall and spring colloquia.

Research Statement
The Breedlove lab studies how steroid hormones influence the developing and adult nervous system, including the generation of sex differences in the brain and spinal cord, and the implications of these sex differences for behavior in animals and humans.
