My research is on connections between representation theory, mathematical physics, geometry and topology, including knot homology, the geometry of symplectic singularities, and categorification. I moved to Waterloo and Perimeter in 2017. In the past, I've been an Assistant Professor at the University of Virginia , Northeastern University and the University of Oregon , a C.L.E. Moore Instructor at MIT , and a postdoctoral fellow at the Institute for Advanced Study . I received my Ph.D. in 2007 from UC Berkeley, under the supervision of Nicolai Reshetikhin, and spent the fall of 2006 at the Center for the Topology and Quantization of Moduli Spaces in Aarhus, Denmark. In Spring 2014, I was a Junior Chair at Université Denis-Diderot (Paris 7) with support from Fondation Sciences Mathématiques de Paris. Before that, I studied at Simon's Rock College and the Budapest Semesters in Mathematics Program . Before I moved to Canada, my research was supported by the NSF under a CAREER award , and graduate and postdoctoral fellowships, and by a Sloan Research Fellowship.
