Das is a life course scholar and a biosociologist. His past research has focused on stress-metabolic pathways through which social pathologies get “under the skin.” A second cluster, based on evolutionary theories, has been on mechanisms connecting egocentric networks and other proximal ecologies to sex hormone levels, and downstream to social or sexual behavior. His current interests lie in genetic and epigenetic patterns in the life trajectory, and cross-setting divergences in life-course regimes.
