Steven A. Haas

Steven A. Haas is Professor of Sociology and Criminology at Pennsylvania State University's College of the Liberal Arts and serves as Scientific Core Director for the Population Research Institute. His research bridges demography, social stratification, and health disparities across the life course, with emphasis on how early life experiences shape aging trajectories.

His educational background includes:

• Ph.D., University of Wisconsin-Madison, 2004
• M.S. in Population Health, University of Wisconsin-Madison, 2002
• M.S., University of Wisconsin-Madison, 2000

Dr. Haas investigates health as both cause and consequence of social inequality, focusing on war exposure, malnutrition, and adolescent health behaviors. His work employs longitudinal cohort studies, international comparisons, and dynamic social network modeling to analyze health disparities from childhood through aging.

Recent publications reveal a trajectory emphasizing childhood adversity's long-term health consequences, with methodological innovation in network simulations and cross-national analyses of aging trajectories and chronic disease burden.

His recognition includes:

• Robert Wood Johnson Health and Society Scholar fellowship
• Editorial board service for Journal of Health and Social Behavior and Demography

He leads NICHD-funded research on peer influences in adolescent mental health and mentors graduate students through interdisciplinary collaborations. As Scientific Core Director, he advances demographic science on health and aging at the Population Research Institute.
