He joined Chicago-Kent in 2015 from Michigan State University College of Law, where he co-founded the ReInvent Law Laboratory, an innovative multi-disciplinary center that focused on the intersection of entrepreneurship, informatics, programming and design thinking to better understand, analyze and design the law.

Professor Katz has published or forthcoming work in a wide variety of academic outlets, including SciencePlos OneScientific Reports, Journal of the Royal Society Interface, Journal of Statistical Physics, Frontiers in Physics, Physica A and Artificial Intelligence & Law.   In addition, his work has been published in legal journals including Cornell Journal of Law & Public PolicyEmory Law Journal, Virginia Tax ReviewIowa Law Review, Illinois Law Review, Ohio State Law Journal, Journal of Law & Politics, and Journal of Legal Education. Professor Katz is currently working on two book projects including an edited volume entitled Legal Informatics (Cambridge University Press 2021) and a book on technology + innovation in law.  Professor Katz has an Erdős Number = 4.

His work has been highlighted in a number of media outlets, including the New York Times, The Wall Street Journal, Financial Times, BBC Radio, Wired, Vox, National Public Radio, Slate Magazine, Huffington Post, 538, Bloomberg Businessweek, ABA Journal, Law Technology News and The American Lawyer.

Professor Katz is an external affiliated faculty at CodeX—The Stanford Center for Legal Informatics. In addition to teaching and researching, Professor Katz serves as an editor of the International Journal of Law and Information Technology (Oxford University Press) and as a member of the Editorial Board of the Journal of Artificial Intelligence & Law (Springer Scientific). He serves on the Editorial Advisory Board for Law Technology News and is a member of the ABA Task Force on Big Data and the Law.

Professor Katz is actively involved in the rapidly growing legal technology industry.  He is the Co-Founder & Chief Strategy Officer of LexPredict (a legal technology and analytics company that was acquired by Elevate in 2018).   He also serves as a formal and informal advisor to a number of legal tech startups.  In addition, he is a member of the advisory board of NextLaw Labs - a global collaborative innovation ecosystem organized with Dentons (the world’s largest law firm). 

Professor Katz received his Ph.D. in political science and public policy with a focus on complex adaptive systems from the University of Michigan. He graduated with a Juris Doctor cum laude from the University of Michigan Law School and simultaneously obtained a Master of Public Policy from the Gerald R. Ford School of Public Policy at the University of Michigan.  During his graduate studies, he was a fellow in Empirical Legal Studies at the University of Michigan Law School and a National Science Foundation IGERT fellow at the University of Michigan Center for the Study of Complex Systems.
