Thaddeus Hoffmeister




I am a professor at the University of Dayton School of Law (UDSL). My teaching and writing focuses on criminal law, technology, and the jury. My most recent book is entitled Social Media Law in a Nutshell. I also edit two blogs Juries and Social Media Law.

I have been widely cited in various media outlets ranging from the New York Times to CNN to Wired magazine and regularly make appearances on television and radio as a legal consultant.

Outside of my work in academia, I teach legal seminars to attorneys and judges around the country.  In addition, I have been a consultant and expert witness on several high-profile cases including U.S. v. Barry Bonds.  I also work as an Acting Magistrate Judge in Dayton Municipal Court and serve as a Judge Advocate General in the National Guard. Recently, I was elected to city council and appointed to the Southwest Ohio Regional Transit Authority (SORTA) Board.

Prior to joining UDSL, I worked on Capitol Hill and clerked for the Honorable Anne E. Thompson, U.S. District Judge for the District of New Jersey. I am admitted to practice law in California, Indiana, Ohio, and Washington, D.C.
