Dr. Dawn DeLay’s research is on social relationships, with a specific focus on how similarities and differences in individual identity during childhood and adolescence affect relationship processes and outcomes. She has a related interest in understanding how and why bias is present in statistical methods and analyses. She teaches on the use of appropriate methodologies and statistical techniques, with a specific interest and expertise in the use and application of longitudinal social network methods and analyses.

Research projects on which Dr. DeLay is currently a principal investigator include:

(1) The APPLE Project designed to support healthy teacher-child and peer relationships in classrooms and to promote gender integration that may reshape gender stereotypes and provide the possibility of more cross-gender peer interactions in public elementary schools.

(2) The Fostering Adolescent School Transitions (FAST) Study which examines the interplay between peer relationships, gender identity, and adjustment outcomes during middle school. 

Dr. DeLay collaborates on interdisciplinary national and international research teams. Collaboration allows her research to expand across disciplinary, cultural and national contexts.
