DeWitt Wallace Professor of Mathematics
Former President, Mathematical Association of America
My research interests lie in number theory and combinatorics, and especially partition theory (how many ways can you express an integer as the sum of positive integers?) with occasional forays into analysis (special functions, modular forms) and algebra (especially the theory of representations of the symmetric group). I am particularly interested in the mathematics of Srinivasa Ramanujan. My doctoral thesis proved and extended a number of his identities. I enjoy the history of mathematics and have drawn on it in my books:
I also have a series of lectures that provide an introduction to the history of mathematics, starting with ancient Babylonian and Egyptian mathematics and continuing through the solution of the Poincaré Conjecture: Queen of the Sciences: A History of Mathematics. These are 24 half-hour lectures available from Great Courses.
