I moved to Fordham University, in NYC! Here's my new webpage.

Here is my CV.

Research interests:

My research is on symplectic geometry, more specifically the kind that involves hamiltonian group actions on symplectic manifolds. I have been working on folded symplectic structures, in particular origami manifolds, and venturing into Poisson geometry via the study of b-manifolds. And I like Delzant polytopes.
I was a graduate student at MIT under Victor Guillemin and I finished my PhD in June 2010.

Teaching at Cornell:

In Spring 2014 I am teaching Math 7620 Seminar in Geometry. We will be focusing on Symplectic Geometry.
In Fall 2013 I taught Linear Algebra (Math 2210), in Spring 2013 Honors Introduction to Analysis I (Math 4130), in Fall 2012 Linear Algebra (Math 2210), in Spring 2012 Math and Politics (Math 1340) and in Fall 2011 Linear Algebra (Math 2210).
