I sometimes have things to say about geometry — or math more generally, both the subject and the ecosystem. This site started as a utilitarian attempt to gather and organize these thoughts.
Where to see me talk in the near future
March 27, 2014: Mathematics Colloquium at University of Arizona.
April 25–27, 2014: AGNES at Stony Brook.
In winter quarter at UCLA, I’ll teach a graduate course on algebraic cycles (Math 216-1) — drawn partly from the book-in-progress, 3264 and All That, by David Eisenbud and Joe Harris and partly from Fulton’s book Intersection Theory.
