Prior to joining the Justice Center, Dr. Zajac was Chief of Research and Evaluation in the Pennsylvania Department of Corrections for thirteen years, where he initiated and led numerous studies and evaluations of PADOC programs and related topics, partnering with external researchers and securing third party grants. The research partnership model that Dr. Zajac developed there won the 2008 Innovations Award from the Council of State Governments, being recognized as a model for knowledge creation and transfer. During Dr. Zajac’s tenure in the PADOC, this model resulted in 18 major grant supported studies totaling over $4 million in external support, and promoted the diffusion of evidence-based practice within the PADOC.
