Here are the links to web-pages for graduate courses that I am teaching or have taught in the recent past:

**Fall semester 2012:**The Nature of Evidence HLS 2480 (a Harvard Law School seminar-course with Noah Feldman)**Fall semester 2012:**Math 124: Number Theory**Spring semester 2012:**History of Science 206r: (with Mark Schiefsky. Devoted to philosophical and historical examination of appeals to motion and other "mechanical" notions in ancient geometry.)**Spring semester 2012:**Mathematics 229: Graduate course in Analytic Number Theory**Fall semester 2011:**Mathematics 124: Number Theory**Fall semester 2010:**Mathematics 122: Algebra I: Theory of Groups and Vector Spaces-
**Spring semester 2010:**- Mathematics 123: Algebra II: Theory of Rings and Fields
- Mathematics 160:The works of John Wallis, and specifically: "Arithmetica Infinitorum." (A seminar-course taught jointly with Mark Reeder).

**Fall semester 2009:**Math 122, Algebra I: Theory of Groups and Vector Spaces**Spring semester 2009:**History of Science 206r: Archimedes and the Archimedean Tradition and Math 123: Algebra II: Theory of Rings and Fields.**Fall semester 2007:**The Theory of Schemes 233a.**Academic year 2006/2007:**Algebraic Number Theory 251a and its continuation Algebraic Number theory 251b.**Fall semester 2008:**Algebraic Number theory 223a. Note: Math 251a in 2006 and Math 223a in 2008 were both taught in collaboration with John Tate. In Math 251a, Tate gave lectures on "Tate's Thesis" while in Math 251a Tate gave lectures on Group cohomology and Class Formations.**Spring of 2006:**Current Results in Modular Forms, 254z. This course was a part of the special program on Eigenvarieties.
