Richard Berk

Emeritus Professor of Criminology and Statistics

Department of Criminology and Department of Statistics

Ph.D., Sociology, The Johns Hopkins University, 1970

B.A., Psychology, Yale University, 1964

Professor Berk is an Emeritus Professor of Criminology and Statistics with past appointments in the Department of Criminology and the Department of Statistics and Data Science at the University of Pennsylvania. He is also a Emeritus Distinguished Professor of Statistics at UCLA. He works on various topics in applied statistics including causal inference, statistical/machine learning, and methods for evaluating social programs. Among his criminology applications are inmate classification and placement systems, law enforcement strategies for reducing intimate partner violence, detecting violations of environmental or worker safety regulations, claims that the death penalty serves as a general deterrent, and forecasts of criminal behavior and/or victimization using statistical/machine learning procedures.
