My research focuses on the globally convergent strategies and optimality conditions of quadratic programming. For practical engineering and economic problems such as critical node mining in complex networks and rumor blocking, I have constructed systematic quadratic programming models and designed efficient and feasible algorithms for accurate solution. I have presided over 1 Youth Fund Project of the National Natural Science Foundation of China, and participated in 6 projects of the National Natural Science Foundation of China as a core member; presided over 1 Excellent Young Teachers Project of the Fundamental Research Funds for the Central Universities; presided over 2 research projects commissioned by government departments and enterprises. Up to now, I have published more than ten academic papers in SCI-indexed journals.
