Jennifer researches the intersection of criminal and immigration law and enforcement.  Her work has explored the regulation of human trafficking and the securitization of immigration law. Recently, she has focused upon the expanding participation of state and local law enforcement agencies in U.S. immigration enforcement and the failure of legal systems to provide adequate deterrents to unlawful immigration policing practices. She has also done research focusing on the substantive and procedural issues raised by the increasing reliance on the criminal justice system as a tool for managing migration.
