Brief Introduction of Professor Song Jiang

Song Jiang, an applied mathematician, is Professor at the Institute of Applied Physics and Computational Mathematics (IAPCM). He took an undergraduate degree (B.Sc) in 1982 at Sichuan University, received a master degree in 1984 at Xi'an Jiaotong University and a Ph.D in 1988 at University of Bonn. He also received a Habilitation degree in 1996 at Germany. He was elected as an academician of Chinese Academy of Sciences in 2015.

Song Jiang’s main research areas lie in mathematical theory, computing methods for compressible fluid mechanics and their applications. He has made a series of significant achievements in well-posedness and low Mach number limits for (multi-dimensional) compressible Navier-Stokes equations, and the mathematical analysis for the Rayleigh-Taylor instability in gas dynamics and MHD. Especially, for any adiabatic exponent γ>1, collaborated with others, he proved existence of weak solutions to three-dimensional steady compressible Navier-Stokes equations with large forces. Besides, aiming at the difficulties of multicomponent large distortion and mesh distortion in numerical simulation of weapon physics, he put forward in cooperation several practical new algorithms and developed a software platform for numerical simulation of major weapon models.

Among many awards he has received include: Second prize of Chinese National Natural Science, First Prize of the Military Science and Technology Progress, The National Award for Youth in Science and Technology, and Qiushi Outstanding Youth Award.
