Professor Ewald teaches courses in constitutional law and American politics. Within public law, his current research focuses on criminal justice, specifically on the restrictions of rights and privileges that often accompany a conviction – what are sometimes called the “collateral consequences” of criminal-justice involvement.   He is author of The Way We Vote: The Local Dimension of American Suffrage (Vanderbilt University Press, 2009), and co-editor of Criminal Disenfranchisement in an International Perspective (Cambridge University Press, 2009).  His work on felony disenfranchisement and other collateral consequences has been published in Criminology, Law & Social Inquiry, Publius: The Journal of Federalism, Social Science Quarterly, the Fordham Urban Law Journal, the Wisconsin Law Review, and the Columbia Human Rights Law Review.

He served as Interim Associate Dean of the Honors College in 2014.
