Biography

Sam Trejo is a sociologist interested in how social and biological factors jointly shape human development across the life course. He specializes in quasi-experimental, computational, and biosocial quantitative methods, typically utilizing large administrative datasets and longitudinal studies that contain molecular genetic data. His research investigates polygenic scores, which are measures of a person’s genetic predisposition for various traits, ranging from height to depression and cognitive ability. These polygenic scores are becoming predictive of social, behavioral, and health outcomes. His work focuses on understanding how social environments can mediate, moderate, and confound the associations between genes and outcomes. He also leverages field natural experiments to explore the processes that produce educational and health inequality, emphasizing the reciprocal relationships between education and health. For instance, his research examines issues such as childhood lead exposure, fatal school shootings, and economic segregation.
