Thomas D. Lyon’s research interests include child witnesses, child maltreatment and domestic violence. He teaches courses in Evidence, Law and Psychology, and Child Interviewing. Professor 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.
Professor 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 60 papers in law reviews, psychology journals and books; has authored or co-authored more than 90 research presentations at psychology and law conferences; and has conducted more than 200 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, Professor Lyon received his Ph.D. 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.

G. Book Reviews
FACULTY IN THE NEWS
Michael Chasalow was quoted about a legal dispute over the ownership of fact-checking site Snopes.com. “"Of course the underlying issue is whether the sale resulted in five individual owners or ownership by Proper Media," he e-mailed. “It seems most likely that Proper Media assumed that the individual owners would act in Proper Media’s interest, but it is not clear whether the five individuals had contractual obligations to do so. If the sale resulted in five owners who were not bound by contract to act in a certain way, then any one of the owners would, in theory, be free to act individually, with Mikkelson. On the other hand, the five individual owners could have contractually agreed to vote for a certain director or directors (for example the president of Proper Media), but such a provision would need to be clearly articulated along with consequences for not following such a provision."
