Matthew Hagler completed his Bachelor of Arts in psychology and English from Sewanee, the University of the South, a year-long Fulbright student fellowship in Turkey, and his Master of Arts and Doctor of Philosophy in Clinical Psychology from the University of Massachusetts Boston. Dr. Hagler’s graduate work was supported by a Graduate Research Fellowship from the National Science Foundation. Following graduate school, Dr. Hagler then completed two years of full-time clinical training as a predoctoral intern and postdoctoral associate at the Yale School of Medicine. He earned his South Carolina license in clinical psychology and joined the faculty at Francis Marion University in 2022.
Dr. Hagler’s research investigates the antecedents, processes, and outcomes of intergenerational social support. Much of this work has focused on mentoring relationships between youth and nonparent adults – including formal relationships within organized youth programs (e.g., Big Brothers Big Sisters), as well as bonds that arise organically within families, schools, extracurricular activities, and communities. Dr. Hagler’s work is highly interdisciplinary, integrating clinical, community, educational, and developmental psychology, using both quantitative and qualitative methods. Dr. Hagler maintains an active research group and encourages undergraduate and graduate students interested in gaining research experience to contact him about current opportunities.
Clinically, Dr. Hagler works with children, adolescents, young adults, and families from diverse, underserved backgrounds. He has a particular interest in supporting recovery from complex trauma and mitigating risk for developing serious mental illness (SMI). His theoretical orientation integrates cognitive-behavioral, mindfulness/acceptance-based, and relational-cultural approaches.
