Professor Barker has dedicated his scholarly pursuits to the area of income taxation and more specifically to the study of international and comparative taxation. A three-time Fulbright recipient, he has conducted research as a visitng professor at the South African universities of Cape Town, Free State, Witwatersrand, and at the Riga Graduate School of Law (University of Latvia). His research reflects a strong normative approach to tax law that emphasizes the role of tax avoidance and important social values in the development of tax law in societies adopting free market, democratic systems in both the developed and emerging and transitional economies. In 2006, Professor Barker received the prestigious ATAX Research Fellowship to support the research programs of the tax institute of the University of New South Wales in Sydney, Australia. He serves as the United States’ contributing editor for Intertax, the leading international tax journal.
