Yueqing primarily works on first-principles calculations for condensed matter systems with strong correlations. Her research interests focus on developing methods to systematically derive renormalized model Hamiltonians from highly accurate many-body calculations, using techniques including real-space quantum Monte Carlo. Recently, she has been working on improving the state-of-the-art quantum embedding and downfolding frameworks by comparing them with ab initio many-body calculations. She is also interested in simulations of realistic materials using first principles.
