Elizabeth Tippett studies behavioral ethics, employment law and decision-making. Her recent research examined how employee timekeeping software can erode compliance with wage and hour laws, and she has studied how contract terms may predict a company’s litigation risk. Tippett is also studying drug injury ads, through which attorneys recruit consumers for lawsuits against pharmaceutical companies. Although these ads contain strong warning about medical risks, deceptive content in those ads remains largely unregulated. She is a co-author of the fifth edition of the textbook "Employment Discrimination & Employment Law: The Field as Practiced," and her research on disparate impact litigation has been cited in opinions issued by the U.S. Court of Appeals and Iowa Supreme Court. Her writing has appeared in the New Republic, Slate and The Daily Beast, and she has appeared on the BBC, Sirius Satellite Radio and Oregon Public Radio. In June 2017, Tippett testified before the House Judiciary Subcommittee on the Constitution and Civil Justice, regarding mass tort advertising.
