Through program development, implementation, and evaluation, she aims to address this trend by strengthening characteristics of teachers, classrooms, and schools associated with the successful schooling of diverse students. Her research interests also include understanding the promise of restorative approaches to school discipline. She has authored 50 peer-reviewed journal articles and numerous book chapters.
