My research is related to the study of supersymmetric gauge theories as non-perturbative formulations of superstring/M-theory using the gauge/gravity duality. I am interested in numerical studies of the maximally supersymmetric gauge theory using Monte Carlo simulations to predict and confirm results from the supergravity (SUGRA) side. This is a non-trivial check of the duality extending beyond the usual AdS5/CFT4 when the field theory is non-conformal (in space-time dimensions not equal to four). I am also interested in exploring thermal phase structures of multi-matrix models (such as BMN/bosonic sector of BFSS) and understanding deconfinement transitions. I am also exploring tensor networks methods to study lower-dimensional gauge theories such as SU(2) gauge-Higgs models and spin models with continuous/discrete symmetries and interesting models with sign problems that are not tractable by Monte Carlo methods.
