Sam Trejo

Sam Trejo is a PhD candidate in Sociology, Economics, and Education at Stanford University and an NSF and IES Graduate Research Fellow. He has also earned two MA degrees at Stanford, one in Economics and one in Sociology. Before coming to Stanford, Sam received his BA from The University of Texas with a double-major in Economics and Plan II Honors, as well as minors in Math and Arabic.

His research explores how social, environmental, and genetic factors combine to shape human development and the implications for public policy. Sam specializes in a wide range of quantitative tools, including quasi-experimental, computational, and biosocial methods. A driving theme of his work is the reciprocal relationship between education and health across the life course. Apart from quantitative social science research, Sam enjoys camping, bikes, board games, and Chinese food.
