*** Dr. McQuillin is accepting students for Fall 2022 ***


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) promote positive youth development. In this work, I hope to improve the positive influence of these relationships by equipping helpers with skills and knowledge gleaned from research evidence.

As faculty in the School Psychology Ph.D. program, I help prepare future scientist-practioners who want to work with school-aged children and their caregivers. After graduating, my doctoral students have been employed in hospitals, academic research settings, private practice, and K-12 school settings. I am also affiliated with the department's Quantitative Psychology Area of Emphasis and I serve as a quantitative methodologist on a broad range of research projects. 

Fall 2022 School Psychology Doctoral Applicants:
I will be accepting School Psychology doctoral students for Fall 2022. 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.
