Tracey Evian Waasdorp CIRP@CHOP
Violence Prevention Initiative Fellow

Tracy Evian Waasdorp, PhD, MEd holds a joint appointment as a Research Scientist at The Children’s Hospital of Philadelphia (CHOP) and at the Johns Hopkins Bloomberg School of Public Health (JHSPH). At CHOP, Dr. Waasdorp focuses on prevention and intervention of bullying with urban minority youth. Specifically, she contributes to the content, methods, and design of measures, and to testing the effectiveness of two interventions designed to reduce aggression and bullying among urban elementary aged youth (Partner for Prevention/PRAISE and Friend-2-Friend) and the Free2B bullying prevention assembly. Both programs are part of CHOP’s Violence Prevention Initiative (VPI). A VPI Fellow, she is also a co-investigator on a grant aimed at designing a bullying prevention mobile application to accompany Free2B.

At JHSPH, Dr. Waasdorp is the lead analyst or co-investigator on many grants, including one related to a comprehensive measure of school climate for middle and high school students (MDS3). She is principal investigator on a grant that aims to address bullying using an innovative, transportable training simulator combined with an evidence-based teacher-coaching model.

Dr. Waasdorp publishes on school-based bullying prevention/intervention, forms of bullying and victimization, coping with bullying, teachers’ perceptions and responses to bullying, parent–child relationships surrounding peer relationships, and school safety, climate, and connectedness. Many of her publications employ complex statistical modeling, including hierarchical linear, latent variable, measurement invariance, and mixture modeling.

Dr. Waasdorp’s research has been supported by the National Institutes of Health, the Centers for Disease Control and Prevention, the National Institute of Justice, the Department of Education, the National Science Foundation, the Pew Charitable Trusts, and the W.T. Grant Foundation. She earned her Master's from the University of Pennsylvania, her PhD from the University of Delaware, and completed her post-doc at Johns Hopkins. Dr. Waasdorp can be contacted at
