Weiran Sun

Weiran Sun is a Professor in the Department of Mathematics at Simon Fraser University (SFU), part of the Faculty of Science. His research focuses on partial differential equations (PDEs), kinetic theory, and applied analysis, with recent interests expanding into AI applications in mathematics. He holds a Ph.D. in Applied Mathematics and Scientific Computation from the University of Maryland (2008).

Research interests include:

• Analysis and numerical methods for kinetic equations
• Inverse problems related to kinetic theory
• Mathematical collaboration with computer scientists (e.g., DeLTA Lab at SFU for LLMs in applied math)

Recent work highlights:

• Development of PDE-Controller using LLMs for formalization/reasoning of PDEs
• Studies on crossover transport phenomena and diffusion limits
• Contributions to numerical analysis of nonlocal equations (e.g., Lévy-Fokker-Planck)

Upcoming activities include organizing the 5th SIAM Pacific Northwest Section Meeting (2025) and participating in kinetic theory programs at SLMath (Berkeley). His research spans interdisciplinary collaborations, blending traditional applied mathematics with emerging AI tools.
