Brief Biography

Nancy Steblay, Ph.D., is Professor of Psychology at Augsburg College. As an experimental psychologist, Dr. Steblay has conducted research on eyewitness memory for 25+ years and has published numerous peer-reviewed scientific articles and chapters on eyewitness topics. She serves as a reviewer for the National Science Foundation and multiple science journals, and is a member of the Editorial Boards of Law and Human Behavior and Applied Cognitive Psychology. Audiences for recent professional presentations have included prosecutors, defense attorneys, law enforcement, policymakers, and forensic scientists.

Dr. Steblay has worked with law enforcement to implement revised field lineup identification procedures based on eyewitness science. Her field and laboratory experiments have been funded by the National Institute of Justice and the National Science Foundation, and she was part of the scientific team for a national study of eyewitness field lineup procedures conducted by the American Judicature Society.
