I am an H.C. Wang Assistant Professor in the Mathematics Department at
Cornell. My mentor is Reyer Sjamaar.
Previously I was an Eberly Postdoctoral Fellow at Penn State mentored by Nigel Higson,
and before that I was a PhD student in Toronto under the supervision
of Eckhard Meinrenken.
My research interests are symplectic/Poisson geometry, moduli spaces and index theory.
