John Pfaff, a Fordham University law professor, teaches criminal law, sentencing law, and law and economics.
Before coming to Fordham, he was the John M. Olin fellow at the Northwestern University School of Law and clerked for Judge Stephen F. Williams on the U.S. Court of Appeals for the D.C. Circuit.
Pfaff’s research focuses primarily on empirical matters related to criminal justice, especially criminal sentencing. He has paid particular attention to the unprecedented 40-year increase in U.S. incarceration rate.
His research also looks at how to incorporate evidence-based practices into the judicial review of scientific and empirical evidence.
