Research

My research applies Bayesian and frequentists methods to answer statistical questions in the criminal justice policy setting. Specifically, I examine non-traditional predictors of recidivism, conduct specific program and evaluation studies, and conduct exploratory analyses using various statistical packages in R and Python.
