In addition to marijuana law, Professor Osbeck's research interests include legal writing, legal research, judicial decision-making, and predictive legal analysis. Before joining Michigan Law in 2001, Professor Osbeck was a partner in the Denver office of a large law firm.

Professor Osbeck received an AB, with high distinction, from the University of Michigan, an MA in philosophy from the Johns Hopkins University, and a JD, cum laude, from Michigan Law. While attending Johns Hopkins, he received a University Fellowship, the top departmental award. In law school, he received certificates of merit for legal writing and political philosophy, and was a note editor for the Michigan Journal of Law Reform. Following his law school graduation, he served as a judicial clerk for Michigan Supreme Court Justice Charles L. Levin.
