I am a Professional Specialist at Princeton University with a Ph.D. in criminology from the University of Pennsylvania. I work on multidisciplinary teams conducting causal and quasi-experimental research on public-safety and justice outcomes, with an emphasis on making complex evidence accessible and actionable for non-specialists.

My recent work focuses on racial disparities, representativeness in policing, and the effect of Taylor Swift concerts on crime. For more than 10 years, I have independently built and maintained a public-safety data pipeline that compiles and harmonizes hundreds of annual files spanning 1960–2024 across more than a dozen datasets, designed for reliability, documentation, and repeatable updates.

My data products have been downloaded 15,000+ times and cited 250+ times. I also built the Crime Data Tool , a public-facing platform that helps non-technical users explore trends in crime, arrests, and police employment across jurisdictions. I have published 15 peer-reviewed articles and authored a practical programming textbook (CRC Press) designed to teach novices how to clean and work with real-world data. I collaborate with partners across academia, government (including the U.S. Department of Justice), and public-interest organizations to define requirements, set priorities, and deliver clear, usable outputs.

I also consult on public-safety data projects and litigation, supporting organizations that need reliable data pipelines, documentation, and reproducible analysis.
