In 2008, Jones joined the faculty of the Harvard Graduate School of Education (HGSE) as an assistant professor.[4][1] That same year, she was a recipient of the Grawemeyer Award in Education for the book A Vision for Universal Preschool Education, co-authored with Edward Zigler and Walter Gilliam.[2][4][3] She was promoted to associate professor in 2012, holding the title of Marie and Max Kargman Associate Professor in Human Development and Urban Education Advancement.[4][1] In 2013, she received the Joseph E.

Jones's research is anchored in prevention science and examines the impact of poverty and exposure to violence on the social, emotional, and behavioral development of children and youth.[2][3] Her work involves evaluating social–emotional learning (SEL) interventions in preschool and elementary schools and developing new curricula.[2][3] She emphasizes conducting rigorous scientific research that produces accessible content for practitioners and policymakers.[2][3]
