Sophie P. Barnes, EdM, is a doctoral candidate in the Human Development, Learning and Teaching concentration at the Harvard Graduate School of Education. Her research centers on understanding the setting- and individual-level mechanisms that support children’s social, emotional, and behavioral skill development in school contexts, with a focus on executive function and self-regulation. She is also interested in adding nuance and precision to the measurement of social and emotional learning (SEL) and partnering with schools and districts to develop effective assessment plans. Prior to beginning her doctoral studies, Ms. Barnes worked in the EASEL Lab led by Stephanie M. Jones on a number of evaluations of school-based interventions that target children’s SEL growth and development, as well as research and translational writing projects.
