Personal Statement

Personal Statement

Dr. Johanna M. deLeyer-Tiarks is an Assistant Professor of School Psychology in the Gordon F. Derner School of Psychology at Adelphi University and Director of the Center for Education and Intervention Research (CEIR).

She earned her Ph.D in Educational Psychology at the University of Connecticut and holds dual Master's degrees in both Educational Psychology and Community Psychology. 

Dr. deLeyer’s research centers on the development and investigation of evidence based interventions to promote positive behavioral, academic, social-emotional, and physical health outcomes. She is particularly interested in mind-body health and self-modeling interventions. Recently, her work has focused on investigating the utility of virtual reality as a tool to facilitate remote implementation of self-modeling interventions for stuttering. She is also completing research on video self-modeling as an intervention for gender affirming vocal training, and relaxation and guided imagery as a treatment for asthma.

Her other current research interests include the identification and remediation of academic disparities experienced by LGBTQ students during the high school to college transition period.
