During the 2022-2023 academic year he is on leave while serving as a Senior Fellow at the Securities & Exchange Commission, Division of Corporation Finance. He also serves as a research fellow in the IRS Joint Statistical Research Program and the U.C. Irvine/Student Loan Law Initiative.

Before Georgetown, he taught at Boston College and Florida State, and visited at George Washington and San Diego law schools. Prior to academia, he was a federal prosecutor in the Criminal Appeals and Tax Enforcement Policy Section in the Tax Division of the U.S. Department of Justice and worked as a law clerk for Judges Robert A.

In 2012, together with four colleagues, he was signatory to an amicus brief in NFIB v. Sebelius, the case challenging the constitutionality of the Affordable Care Act. The Supreme Court upheld the statute as a proper exercise of Congress’ taxing power, following closely the reasoning argued in the amicus brief.
