I have been a postdoc in the TopOpt group at the Technical University of Denmark (DTU) since February 2026. Previously, I was a postdoc in the Computer Graphics & Visualization group at the Technical University of Munich (TUM). I received my PhD in Computer Science from TUM in 2023, graduating with the highest distinction (summa cum laude).

My research focuses on lightweight structural design and optimization, with an emphasis on large-scale numerical simulation and computational methods. I work on problems spanning topology optimization, stress tensor visualization, geometric modeling, and manufacturing-aware design. I also develop open research tools to support these workflows.

News

• [2026.01] - Our PSLshell paper is about to appear in CMAME, a cap of my career at TUM. From 2026.02, I will start a new Postdoc journey in the TopOpt group at the DTU, Denmark.
• [2025.09] - Our work about conducting large-scale topology optimization with MATLAB is published on SMO.
• [2025.05] - The MATLAB code (TOP3D_XL) for conducting high-resolution Topology Optimization is out.
• [2025.05] - Our latest paper on SGLDBench is published on TVCG.
