Kimberly E. K. DeMarco, Ph.D.

Dr. Kamper-DeMarco received her Ph.D. in Clinical Psychology from the University at Buffalo. She joined the faculty at Buffalo State in 2018. As a licensed Clinical Psychologist, Dr. Kamper-DeMarco is interested in how peer victimization and aggression contributes to the development of psychopathology in children and adolescents. Recently, she is interested in examining how children’s self-regulatory skills may place them at risk for victimization by their peers.

Current Research Projects

Attribution Development Project

I am currently recruiting 3-5 year olds and their parents for a study aimed to understand how attributions around peer relationships develop in young children.
