I have moved to Institut de Mathématiques de Jussieu in Paris.
I was a student of Denis Auroux at MIT, and then a researcher at MSRI, Cambridge University, and Stanford University.
In the Spring 2013 quarter I taught Math 53 - Ordinary Differential Equations with Linear Algebra.
In the Fall of 2012 I taught Math 115, Functions of a Real Variable and in the Spring 2012 I taught Math 51, Linear Algebra and Multivariable Differential Calculus.
I sometimes give talks at Berkeley Math Circle and Stanford Math Circle and San Jose Math Circle.
Based on one of the sessions, I have written an exposition on the Baby Hummer card trick, a trick from the Magical Mathematics book by Persi Diaconis and Ron Graham.
I was a mentor at 2008 Research Science Institute.
My research is in symplectic geometry, with a focus on Floer-theoretic invariants of open symplectic manifolds.
Here are the slides from the special session on Symplectic and Contact geometry at the AMS meeting in Rochester (here are also some old slides from the meeting in Worchester in 2009).
And here are notes on spectral flow in Morse theory. These are to be updated and supplemented with notes on spectral flow in Hamiltonian and Lagrangian Floer homologies.
