• Design and development of first-principles computational methods, especially the continuous-time quantum Monte Carlo impurity solver.
• Applications of first-principles calculations onto studies of electronic structures of strongly correlated materials including iron-based superconductors, Mott insulators, and functional materials such as ferroelectrics and other transition-metal oxides.
• Our results, published on top-tier journals, are not only essential in the discovery of barely studied paradigms in theoretical condensed matter physics, but also useful to explain the latest experiments and make predictions for further studies.
