“If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.” — John von Neumann
Welcome to my blog! I am a visiting scholar at the CUNY Graduate Center. My research is in an area of Mathematics called Set Theory. At the very foundation, all mathematical objects are sets. Set Theory, which studies the properties of sets, explores the foundations of mathematics. My CV is here.
I am a coorganizer of the CUNY Set Theory Seminar at the Graduate Center. I am the webmaster for the NYlogic website. Follow CUNY logic seminars Follow @CUNYLogic.
