Tony Stillfjord

Tony Stillfjord is an Associate Professor at the Centre for Mathematical Sciences, Lund University, Sweden. He previously held postdoctoral positions at the Max Planck Institute for Dynamics of Complex Technical Systems and Chalmers/University of Gothenburg.

• Ph.D. and MSc in Numerical Analysis from Lund University
• Funded by WASP (Wallenberg AI, Autonomous Systems and Software Program)

Research Interests: Numerical methods for partial differential equations, splitting schemes, stochastic optimization, and large-scale differential Riccati equations. His work focuses on developing low-rank approximations and robust optimization algorithms.

Recent Publications highlight advancements in Lie/Strang splitting for operator-valued Riccati equations, stochastic descent methods, and GPU-accelerated splitting schemes.

Software Contributions: Developed DREsplit (MATLAB package for differential Riccati equations) and BST20_CODE for stochastic optimization experiments.
