Faculty Focus: Meet Professors John Dzienkowski and Robert Peroni

(This article marks the fourth in a series highlighting members of the UT Law faculty.)

Since April is tax month it seems appropriate to spotlight two faculty members whose expertise includes taxation. Inasmuch as their scholarly interests coincide and have led to personal friendship as well as professional collaboration, we bring both of them to you in this article.

John Dzienkowski is the John S. Redditt Professor in State and Local Government. A summa cum laude graduate of the University of Miami, Dzienkowski’s ties to UT Law School are many. He is a 1983 graduate of UT Law, and where he graduated with high honors. Following law school, Dzienkowski clerked for two UT Law alumni: the late Joseph Sneed, ’47, of the U.S. Court of Appeals for the Ninth Circuit, and the late Robert Keeton, ’41, federal district judge for the District of Massachusetts. He began his teaching career at Tulane Law School, but returned to Texas and to the law faculty in 1988.

Dzienkowski is a nationally recognized scholar in the area of professional responsibility of lawyers, and his courses on this subject are highly sought after by students at the Law School, where is he a well known and popular classroom teacher. In 2004, he was honored with the Texas Exes Faculty Teaching Award. He is co-author of, with UT Law’s John Sutton, Professional Responsibility of Lawyers, and he is the editor of the leading statutory supplement on Professional Responsibility: Standards, Rules, and Statutes. He is a two-term member of the drafting committee of the Multistate Professional Responsibility Examination.

Dzienkowski also teaches and writes in the areas of real property, energy transactions, and oil and gas taxation. He is a founding co-author of the first commercially produced casebooks on Natural Resources Taxation and International Petroleum Transactions. He is also the author of numerous leading articles on topics related to conflicts of interest in lawyering, including two with his colleague Bob Peroni, “Multidisciplinary Practices of Law” (69 Fordham Law Review 83) and “Lawyer Equity Investments in Clients” (81 Texas Law Review 405). Dzienkowski and Peroni serve as co-chairs of a bi-annual program on oil and gas taxation, the Parker Fielder Oil and Gas Tax Conference, sponsored by UT Law School and the Internal Revenue Service. Dzienkowski is also a co-founder of a prominent blog on issues related to legal ethics called

Bob Peroni is the James A. Elkins Centennial Chair in Law. He earned his undergraduate degree from DePaul University, his law degree from Northwestern University School of Law, and the LLM from New York University Law School. Peroni joined the UT Law faculty in 2003 from George Washington University Law School. His primary areas of teaching and scholarship are federal income taxation, international taxation, natural resources taxation, and professional responsibility and legal ethics. Peroni is an internationally renowned scholar in the areas of international taxation and energy taxation. He is the co-author of five books related to taxation and professional responsibility, including Natural Resources Taxation with Dzienkowski, and the three-volume treatise U.S. International Taxation, and the widely used casebook Taxation of International Transactions.

In addition to his role as co-chair of the Parker Fielder Oil and Gas Tax Conference, Peroni also serves as co-chair of the Annual Institute on Current Issues in International Taxation, co-sponsored by the IRS and George Washington University Law School. He has served as professor-in-residence with the Office of Chief Counsel of the IRS, and as one of the academic advisors to the Joint Committee on Taxation’s Study of the Overall State of the Federal Tax System. He has been active on committees of the American Bar Association’s Section of Taxation and has served as the chair of the Taxation Section of the Association of American Law Schools. He is also a Fellow of the American College of Tax Counsel.

Like his colleague John Dzienkowski, Peroni is a popular classroom teacher as well as a highly regarded scholar. In 2006, he was the recipient of the Texas Exes Faculty Teaching Award. At Tulane, where he taught law before his move to D.C., he was the first recipient of the Felix Frankfurter Distinguished Teaching Award, and he was twice selected by graduating seniors at George Washington University Law School to receive that school’s Distinguished Faculty Service Award.
