Joshua Jackson is a Professor of Psychological & Brain Sciences at Washington University in St. Louis, holding the endowed Saul and Louise Rosenzweig Professorship of Personality Science. His research focuses on personality development and assessment within the Department of Psychological & Brain Sciences, where he maintains an active laboratory in Somers Family Hall. His academic credentials include a PhD from the University of Illinois, Urbana-Champaign and a BS from the University of Wisconsin, Madison. These foundational experiences established his expertise in psychological methodology and longitudinal research design. Professor Jackson's research program investigates the genetic and environmental antecedents of personality change, with particular emphasis on educational experiences as catalysts for development. He examines methodological challenges in personality assessment, comparing self-reports, observer-reports, behavioral observations, and physiological measures across the lifespan. His work bridges theoretical personality psychology with real-world applications in health, relationships, and occupational outcomes. Analysis of his 2012-2014 publications reveals consistent themes: personality's role in predicting life outcomes (divorce, longevity, occupational success), the plasticity of traits in adulthood, and innovative methodological approaches to longitudinal assessment. His research demonstrates how personality traits interact with major life transitions including marriage, retirement, and military service. While no specific awards are documented in the provided materials, his work appears in premier journals including Psychological Science and the Journal of Personality and Social Psychology. Information regarding graduate student mentoring and research funding sources remains unspecified in available records.
