About Me

I'm currently a Senior Lecturer in the Mathematics department at Columbia University, where I teach, do research, and am responsible for the department Computer system.  For the past couple years, I've also been our Calculus Director, coordinating Calculus teaching and implementing our use of the WebAssign online homework system in some of the Calculus classes.

My academic background includes undergraduate and master's degrees in physics from Harvard, a Ph.D. in particle theory from Princeton, and postdocs in physics (ITP Stony Brook) and mathematics (MSRI Berkeley).  I've been at Columbia since 1989, starting here as Ritt assistant professor.

Research

My general area of research interest is the relationship between mathematics (especially representation theory) and fundamental physics (especially quantum field theories like the Standard Model).  Recently I've been working more specifically on understanding whether certain quantum field theories can usefully be formulated in terms of a generalization of the notion of an "automorphic representation", which is central to the Langlands program in number theory.

Blog

Since 2004 I've maintained an active blog called Not Even Wrong, which deals with topics in physics and mathematics.  At the end of 2011 it had 13,378 subscribers at Google Reader.  It now contains over 1000 postings that may be of some sort of interest.

Not
        Even Wrong

My book Not Even Wrong was published in June 2006 in England by Jonathan Cape, in the US in September 2006 by Basic Books.  Translations have appeared in French, Italian, Czech and Korean.  I'm maintaining web-pages for links to reviews, and errata.
