Biography

.
.
.
.
My name is Sam Trejo—I am a quantitative social scientist interested in how social and biological factors combine to shape human development and the potential implications for public policy. I specialize in quasi-experimental, biosocial, and computational methods and am particularly interested in the reciprocal relationship between education and health across the life-course. My work capitalizes on two data sources that, until relatively recently, were unavailable to researchers: (1) large administrative datasets and (2) longitudinal studies containing molecular genetic data.

Last year, I wrote an op-ed about how my experiences with nerve damage and chronic pain led me to donate a kidney to a stranger. When not puzzling over human behavior, I enjoy camping, riding bikes, playing board games, and eating Chinese food.
