He is the recipient of numerous awards, including the Justice for Animals Award and the Colorado Criminal Defense Bar’s Gideon Award. He was a visiting Professor at Harvard Law School for the Spring 2020 semester.
Prior to coming to DU, Marceau was an assistant federal public defender specializing in capital habeas and a law clerk for the Ninth Circuit Court of Appeals. Before law school, he spent a year living and working in Cairo, Egypt.
Marceau’s research focuses on criminal law and constitutional law, particularly as those areas intersect with social change. He specifically writes in the areas of Habeas Corpus, Constitutional Law, and Animal Law. His current research is at the intersection of animal law and criminal law.
His work has appeared in some of the leading academic publications, including the Cambridge University Press, the Yale Law Review, and the Columbia Law Review. He has lectured on his research in the U.S. and in Europe, has been retained as an expert witness in criminal and civil cases, and received grants and awards for his research from a variety of organizations. He has also maintained a law practice while teaching at DU, representing indigent persons, persons sentenced to death, and a wide range of public interest non-profits. He also frequently authors or contributes to amicus briefs.
Marceau received a JD from Harvard Law School and a BA from Boston College. He enjoys running, wildlife viewing, and watching the Big Lebowski.
