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 more recently venturing into Poisson gometry via the study of b-manifolds.
I was a graduate student at MIT under Victor Guillemin and I finished my PhD in June 2010. I am currently a lecturer at MIT, and will be starting as a postdoc at Cornell University in August 2011.
