Li Qi, a male born in October 1990 in Jiuquan, Gansu province, currently serves as an associate professor and master's supervisor. He has been a member of the faculty in the School of Science at Chang'an University since August 2020. He earned his Bachelor's and Master's degrees in Mathematics from Lanzhou University in June 2013 and June 2016 respectively. Additionally, he achieved a Ph.D. in Mathematics from Xi'an Jiaotong University in June 2020.

Qi's research focuses on numerical solutions of partial differential equations and their applications in scientific and engineering computations. His current primary research area involves efficient numerical algorithms for phase-field models (diffusion interface models) and two-phase flow problems. He has published over 10 papers in journals such as Computer Physics Communications, Journal of Computational and Applied Mathematics, Advances in Computational Mathematics, Applied Mathematics Letters, and Journal of Scientific Computing.
