Research


I was previously interested in physics beyond the standard model. Currently, I study the nonperturbative

dynamics of general quantum field theories, using a variety of tools, from supersymmetry, branes, and

dualities, to lattice field theory and Monte-Carlo simulations. My most recent publications:


“Mutli-fractional instantons in SU(N) gauge theory on a twisted four-torus”

with Mohamed Anber, arxiv:2307.04795[hep-th]


“Noninvertible anomalies in SU(N)xU(1) gauge theories”

with Mohamed Anber, arxiv:2305.14425[hep-th]


“Gauge theory geography: charting a path between semiclassical islands”

with F. David Wandler, arxiv:2211.10347[hep-th]
