Dong Shijie

Dong Shijie is an Assistant Professor in the Department of Mathematics at Southern University of Science and Technology (SUSTech), Shenzhen, China, holding this position since March 2022 after completing a postdoctoral fellowship at Fudan University (January 2020–February 2022).

His academic background includes:

• PhD in Mathematics, Sorbonne University, Paris (2017–2019)
• Master of Computational Mathematics, Yonsei University, Seoul (2014–2017)
• Bachelor of Mathematics, Ocean University of China, Qingdao (2010–2014)
• Exchange studies at Shandong University, Jinan (2011–2012)

Dong specializes in nonlinear partial differential equations with emphasis on the Cauchy problem for wave equations and Klein-Gordon equations in mathematical physics. His research investigates global existence, scattering behavior, and asymptotic analysis of solutions—particularly in two space dimensions—using advanced energy methods and geometric techniques to establish uniform bounds and reveal hidden structural properties in quasilinear systems.

His eight recent publications demonstrate consistent focus on two-dimensional Dirac-Klein-Gordon and Klein-Gordon-Zakharov systems, with recurring themes of small data solutions, null conditions, and energy estimates. The work shows strong international collaboration and appears in high-impact journals including Communications in Mathematical Physics and SIAM Journal on Mathematical Analysis, reflecting significant contributions to mathematical analysis of nonlinear wave phenomena.
