My research is in the field of strongly coupled quantum field theories and their non-perturbative definitions. I use the lattice regularization approach and Monte Carlo methods as primary tools in my research. I explore quantum critical points of lattice field theories to define quantum field theories rigorously. I enjoy the challenge of constructing efficient Monte Carlo algorithms in my studies. One of the major bottlenecks in my field of research is the "sign problem". I am particularly fascinated by the fermion sign problem and have proposed the fermion bag method to solve it within a class of models. This method allows us to construct new algorithms to study strongly coupled fermionic quantum field theories. Recently I am trying to formulate quantum field theories using qubits, that may some day be studied using quantum computers.
