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:


“Mass-deformed Super Yang-Mills theory on the four-torus: sum over twisted sectors, theta-angle, and CP-violation”

with Mohamed Anber, arxiv:2509.00157[hep-th]


“On the moduli space of multi-fractional instantons on the twisted four-torus”

with Mohamed Anber and Andrew Cox, arxiv:2504.06344[hep-th]


“The Nahm transform of multi-fractional instantons”

with Mohamed Anber, arxiv:2411.11962[hep-th]
