He then moved to Princeton University, where for his graduate studies he worked under the supervision of Leonardo Rastelli, receiving his PhD in 2004.
From 2004 to 2007 he was a post-doctoral researcher at Harvard University, and then from 2007 to 2011 at the Institute for Advanced Study.
Since 2011 he has been working at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario.
He introduced new techniques in the study and design of four-dimensional (N = 2) supersymmetric conformal field theories.
This led to new insights into the dynamics of four-dimensional (supersymmetric) gauge theories.
