Thomas D. Lyon’s research interests include child abuse and neglect, child witnesses, and domestic violence.  He is the Judge Edward J. and Ruey L. Guirado Chair in Law and Psychology at the University of Southern California Gould School of Law. He teaches courses in Evidence, Law and Psychology, and Child Interviewing. Lyon oversees the USC Child Interviewing Lab and Mobile Center which focuses on the maltreatment of children and identifies ways of encouraging children to provide truthful information about abuse, with higher accuracy and reduced trauma to the child. The Lab conducts cutting-edge research on child witness testimony and is one of the only labs in the country to conduct research and forensic interviews in this field of study.

Lyon is past-president of the American Psychological Association’s Section on Child Maltreatment (Division 37) and a former member of the Board of Directors of the American Professional Society on the Abuse of Children. He has published more than 90 papers in law reviews, psychology journals and books; has authored or co-authored more than 140 research presentations at psychology and law conferences; and has conducted more than 270 trainings with judges, attorneys, law professors, social workers, psychologists and reporters. His work has been supported by the National Institutes of Health, the National Science Foundation, the United States Department of Justice, the National Center on Child Abuse and Neglect, the California Endowment, and the Haynes Foundation.

A magna cum laude graduate of Dartmouth College and Harvard Law School, Lyon received his PhD. in developmental psychology from Stanford University. He was an attorney for the Children’s Services Division of the Los Angeles County Counsel and a research associate at Harbor-UCLA Medical Center prior to joining USC Law in 1995.

Re: Susan Estrich

Susan Estrich writes an op-ed about the Health Insurance Portability and Accountability Act is not responding well to the COVID-19 outbreak. She said, "Right now, HIPAA is making it impossible to know whether you have been in contact with an infected person and, in turn, whether you may be infecting a high-risk loved one."
