He has substantial first-chair trial experience, and previously served as an Adjunct Professor at Northwestern University School of Law in the Trial Advocacy program. He is also a frequent author, having published over 25 articles in the nation's leading law reviews and legal journals on topics including the right of privacy, copyright litigation, and contract doctrine, as well as litigation strategy and tactics. He was appointed as a member of the Illinois ARDC Hearing Board, and is also a member of the Advisory Board for the Fair Contracts Project, an initiative focused on counteracting the implications of fine print in standard form consumer contracts.
