“If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.” — John von Neumann

Microblog

Welcome to my blog! I am a visiting scholar at the CUNY Graduate Center. I am a co-organizer of the CUNY Set Theory Seminar. My most recent CV is here.
On my blog, you can learn about my research, find course materials from the classes I taught, and read my thoughts on mathematics, education, and the universe.

Go to the temporary CUNY Logic Seminars page.

Visit Cantor’s Attic, the wiki for mathematical infinity in general and large cardinals in particular, founded by Joel Hamkins and myself. The site, currently in the early stages of development, aspires to become an extensive, detailed repository of current knowledge on large cardinal theory.

Here is my WordPress profile.
