If you are interested in pursuing a MSc degree, please apply to the Perimeter Scholars International (PSI) masters program. If you are interested in working with me as a PhD student, please send me an email at [email protected]. The PSI program offers the simplest route to work with me as a PhD student.

My research primarily focuses on theoretical and mathematical physics, with a particular emphasis on the interplay between quantum field theory (QFT), string theory, algebra and geometry. Much of my work concerns QFTs which are supersymmetric or topological.
