David Hayeslip



Senior Research Associate


I seek to discover what works by applying social science research to answer timely policy and practice questions of importance to the field of criminal justice. This often entails formative evaluation approaches which seek to examine implementation fidelity and providing guidance to those implementing innovative programs as part of the research process.

David Hayeslip is currently the principal investigator for the evaluation of the Los Angeles Gang Reduction and Youth Development Program, the evaluation of the NIJ Forensic Laboratory Efficiency Program, the Assessment of “Cold Hits” Use, and the National Survey of General Purpose Law Enforcement Agencies. Past work has included being the project director for numerous studies funded by NIJ, BJA, OJJDP, BJS and other government agencies in the areas of public and school safety.
