I study how schools and communities can work together to promote emotional, behavioral, and academic wellness in children who are environmentally or developmentally at-risk.  My work focuses on translating theories of child development to pragmatic prevention and intervention strategies. I am particularly interested in how and why relationships between young people and adult helpers (e.g. mentors) influences positive youth development. In this work, I hope to improve the positive influences of these relationships by equipping helpers with skills and knowledge gleaned from research evidence.

I am a research board member of the National Mentoring Resource Center, a Society for the Study of School Psychology Early Career Award recipient, and the director of the University of South Carolina’s and University of Houston’s AMPED Youth Mentoring programs. I am affiliated with the Psychology Department's Quantitative Psychology Area of Emphasis and serve as a quantitative methodologist on a broad range of research projects.

Fall 2019 School Psychology Doctoral Applicants:
I will be accepting school psychology doctoral students for Fall 2019. I encourage students who have strong academic records and interests in school-based intervention research to apply. I am particularly interested in students who have experience with youth mentoring programs, digital media development (e.g. web or software development, audio/video production), or quantitative research methods in applied settings.
