Tuan Samahon teaches and writes in the areas of federal courts and constitutional law. His articles on federal separation-of-powers doctrine, which focus especially on the powers to appoint and remove, have been published in the Stanford Law Review, Ohio State Law Journal, Hastings Law Journal, William & Mary Bill of Rights Journal, the University of Chicago Legal Forum, and the Nevada Law Journal, among others.

Beyond his scholarship, Tuan is engaged in interpreting and fashioning federal constitutional law. He has testified before the U.S. Senate Judiciary Committee, Subcommittee on the Constitution, and has served as counsel in separation-of-powers and Freedom of Information Act litigation in federal trial and appellate courts. In addition to representing others, for a book he is researching, Tuan successfully sued the FBI for the release of agency records detailing high-ranking executive and judicial officers' abuses of power.

Tuan received his B.A. from Brigham Young University and his J.D. from Georgetown University Law Center, where he was an Olin Law and Economics Research Fellow and was co-awarded the Olin Prize in Law and Economics. Prior to entering teaching, he clerked for U.S. District Judge Raymond Jackson on the Eastern District of Virginia and for U.S. Circuit Judge Jay Bybee on the Ninth Circuit.
