Research Interests:

My research interests sit at the intersection of social, developmental, and educational psychology. Specifically, I am interested in the development of both personal and group identities and how those identities mediate behavior (especially in the area of academics). As such, I’ve conducted research and written on the relationship between self-beliefs (e.g., global self-esteem, academic self-concept) and academic achievement and on the relationships between time use, identity, motivation, and academic achievement. I also have current projects underway which examine the construct validity of measures of the self. In addition, much of my research is applied. For example, I have conducted research on the effects of mentoring on youth development (e.g., academic achievement, problem behavior), and have conducted research relevant to educational policy (e.g., impact of modified school calendars, effectiveness of summer school programs).

In addition to these substantive interests, I have strong methodological and quantitative interests. For example, I wrote (with Harris Cooper) an instrument designed to help quantify the strength of inference permitted by a quantitative research study (e.g., randomized trials and quasi-experiments), and am the Co-coordinator for the What Works Clearinghouse’s Technical Advisory Group (TAG). I am also a member of the Standards of Evidence committee for the Society for Prevention Research (SPR), which was responsible for drafting standards for efficacy and effectiveness trials in prevention research, and am preparing a paper on the impact of attrition in randomized studies in education. At Duke, I teach classes in statistics and research design to both graduate and undergraduate students.

Finally, I am a meta-analyst by training, and use the lens afforded by a research synthesis perspective to inform all of the primary and secondary research that I do. I am also interested in moving forward the state of the art in meta-analysis, and as such I continue to work on methodological and statistical issues that can help with this goal.
