I am fascinated with how taxation affects everyones lives and how it can be a tool of development or of oppression. Income taxation is the primary way democratic societies allocate the financial burden of government to its people. As law, its ever-present form or superstructure has implications for a broad spectrum of human activity. It is a dominant aspect of nontax business and investment law areas like real estate, corporate mergers, corporate finance, international business transactions, oil and gas, trusts and estates, sports and entertainment law, patents and copyrights, nonprofit organizations, and employment, as well as many personal areas such as birth and death, marriage and divorce, charity, education, and leisure. Few laws have the force that income taxation has to reach into our private lives and alter our behavior and even our life choices.
I have dedicated my teaching and research to the area of income taxation and specifically to the study of international and comparative tax law. My research reflects a strong normative approach that emphasizes the role that tax avoidance and important social values have in the development of tax law in societies adopting free market, democratic systems in developed, emerging and traditional economies.
I have been quite fortunate in having received three Fulbright grants, an Australian ATAX Fellowship, and a Senior Research Fellowship at the University of London that have enabled me to pursue my goals. I have been a member of the faculties of the London School of Economics and Political Science, Trinity College Dublin, and the Universities of Oxford, Vienna, Cape Town, Witwatersrand and Free State, New South Wales, Queensland and Latvia. These cross-cultural experiences have forced me to continuously reevaluate my research and conclusions.
I believe that to gain insight into the fundamental nature of foreign systems one should, in a sense, go native, that is immerse oneself in the social and legal framework of the other nation. I have had the unusual experience of having taught basic and advanced courses on the tax law of other nations in the United Kingdom, South Africa and the European Union. These experiences, combined with practical insights gained from my work prior to coming to the Law School—where I handled trial and appellate cases for the Tax Division of the United States Department of Justice and served as law clerk to the Honorable Marion Bennett of the United States Court of Appeals for the Federal Circuit—ground my teaching and scholarship.
