I am a Professional Specialist at the Princeton School of Public and International Affairs where I do research on policing. I hold a master's degree and a PhD in criminology from the University of Pennsylvania and a bachelor's degree in criminal justice from Sacramento State. I primarily use R and have written several R packages and a book on R, "A Criminologist's Guide to R: Crime by the Numbers," which has been published by CRC Press. I have also done research on complaints against the police, crime prevention through environmental design, and the effect of both policing and gang takedowns on crime.
