PhD Thesis

December 6, 2013 I finished my PhD thesis at Stanford University under the direction of Solomon Feferman. You can download my thesis here: Unfolding of Systems of Inductive Definitions. If you want a paper version, it can be acquired cheaply from amazon.com, amazon.co.uk, amazon.de, and other book sellers.
