(PhD, The University of Chicago, 2008). Assistant Professor at McGill University since 2011.

I am a social demographer of aging and the life course. My previous work has been on sex and gender, and my current research focus is on population-based sociology with biomeasures. Within this broad area, the major theme is the long-term physiological consequences of social stressors, including stress-metabolic pathways and Allostatic Load. A second bio-social theme is sex hormones, their interaction with social assets (particularly religion), and the relative influence of these factors on partnership and other outcomes. Future goals include extending this work toward oxytocin and vasopressin for social attachment, pro-inflammatory cytokines, basal cortisol, and targeted genes for stress-hormone receptors—all starting to become available in public-use data. My long term agenda is to construct sociologically-nuanced and biologically-sensitive models of the life course, using and further developing the growing array of biosocial datasets.
