About me

My research has delved into simulating hyperbolic partial differential equations (PDEs) within general relativity (GR) and astrophysics. Playing the role enhanced by the service in the computing center, I leverage different computing paradigms, advanced numerical techniques, and modern computing infrastructure to support fundamental research, bridging the capability of the computational domain and the demand of physical science.

Since 2015, I have participated in WLCG, operating a CMS Tier-2 site with support from Taiwan's CMS group. In running the worldwide grid service with CERN, I learned the best-of-practice techniques and tools for distributed computing and general data-intensive science. I joined KAGRA in 2017 and touched on more practical issues in GW detection, like parameter estimation, denoising, and time-series data processing via statistical tools and machine learning. After 2021, I have been partly involved in the operation of the HPC facility and revisiting quantum computing issues recently, primarily from the perspective of a classical computing center.
