For over 40 years, Gary Wells has led the scientific study of eyewitness identifications, system problems, and solutions. In 1998, at the request of the U.S. attorney gen- eral, Wells joined a Department of Justice working group of police, prosecutors, and researchers, which produced a transformative Guide for Law Enforcement. Wells is also lead author of an APA Division 41 white paper, the first in its history. This white paper was revised and published in 2020. Over the years, Wells has worked tirelessly with policymakers, practitioners, and news media to advocate for the kinds of reforms that prevent wrongful convictions.
