About

I am a researcher (Chargé de Recherche) at Inria and a permanent member of the GeomeriX project-team. After earning my PhD from Zhejiang University in 2020, I spent one year each as a postdoctoral fellow at Télécom Paris and École Polytechnique before joining Inria Saclay. My research has been focusing on the numerical foundations of geometric modeling and physical simulation, covering topics such as multiscale analysis, numerical preconditioning and interactive techniques.

Info & Notes

An overview of my main research thread, beginning with pure numerical approaches and later shifting toward analytical and semi-analytical approaches for PDEs, both of which, surprisingly, resonate in certain ways.

Conference collections: Technical papers organized by conference and session, a homage to Ke-Sen Huang's remarkable work making paper browsing fast and easy.

A short note sharing my take on how Inria is structured, recruits, and approaches computer graphics — might be useful for anyone interested in applying to Inria.

Slides for a talk on generalized barycentric coordinates and cage deformation.

Beautiful papers: A personal, completely subjective and biased, selection of papers I find beautiful.

Random thoughts on the use of AI tools.
