Research Interests

I study strongly correlated many-body systems (particularly fermionic ones) numerically. Focuses include the development of efficient quantum Monte Carlo algorithms for studying fermionic systems (fermion bag, meron cluster, and auxiliary field techniques), as well as finding new sign-problem-free ways to study these systems. I've worked on four-fermi theories as well as systems involving gauge fields that interact with matter.
