An enrolled member of the Choctaw Nation of Oklahoma, Dr. Clarkson has consulted, written, and published extensively on tribal finance and economic development and has conducted significant research on the empirical data on Indian mascots. Dr. Clarkson was also a contributing author for the most recent edition Felix Cohen’s Handbook of Federal Indian Law, providing material on tribal finance, economic development, and intellectual property. In 2005, Dr. Clarkson received the first ever grant from the National Science Foundation to study the dynamics of tribal finance. His research and Congressional testimony on tribal access to the capital markets helped lead to the inclusion of $2B of Tribal Economic Development Bonds in the American Recovery and Reinvestment Act of 2009.
