I am a lecturer at School of Mathematics and Statistics, Central South University and working on numerical methods and analysis of PDEs, including high-order decoupled schemes for Stokes-Darcy interface problems, high-order numerical methods for time-fractional PDEs, simulation and analysis of nonlocal phase-field crystal models, etc.
