John is currently a research associate working with Drs. Kate McLaughlin and Leah Somerville at Harvard University. John came here by way of the psychology Ph.D. program at the University of Oregon, and a B.A. in cognitive science at the University of California, Berkeley. Broadly, John is interested in the development of decision-making and learning during adolescence, and how these processes, situated in the context of developmentally normative goals and adverse environments, contribute to mental and physical health. John is passionate about statistical methodology, especially measurement and modeling task behavior, as well as scientific computing. In addition to John's experience supporting projects in adolescent neuroimaging, John has also provided technical and theoretical expertise on longitudinal personality development, dyadic person-perception, and measurement of pubertal development. John is a huge fan of R, Stan, and The Society for the Improvement of Psychological Science.
