Kathryn Thomas, PhD, JD


Kathryn Thomas is an Associate Research Scholar and Clinical Lecturer in Law at Yale Law School and a Postdoctoral Fellow at Yale Law School’s Justice Collaboratory and Yale School of Medicine’s SEICHE Center for Health and Justice. Her research interests sit at the intersection of psychology and the criminal legal system. She is particularly interested in the health-harming impacts of incarceration and wrongful conviction from a legal epidemiological perspective, and factors that impact trajectories of psychological adjustment upon re-entry following incarceration. Clinically, she is a licensed psychologist and has conducted forensic evaluations and provided evidence-based therapy to justice-involved clients in a variety of forensic settings (including a forensic hospital, juvenile court clinic, and forensic drug diversion program), and she currently conducts forensic evaluations (including competency to stand trial, not guilty by reason of mental disease or defect, and mitigation evaluations) in the Division of Law and Psychiatry. She provides training about mental health to Connecticut law enforcement through the Connecticut Alliance to Benefit Law Enforcement’s Crisis Intervention Team (CIT) training program. She graduated with a Ph.D. in Counseling Psychology from University of Wisconsin-Madison and a J.D. from Loyola University Chicago School of Law. She recently completed her clinical internship at Yale School of Medicine’s Doctoral Internship in Clinical and Community Psychology. She is a licensed attorney in the state of Connecticut, and has experience in criminal defense, post-conviction appeals, and civil rights litigation.
