In Hong Kong, 2019

I am a PhD student at ETH Zurich with Prof. Bernd Bickel. Before moving to Zurich, I spent one year as an intern at IST Austria with Bernd, and also briefly enrolled at EPFL. I graduated from CUHK with a BSc. in Computer Science (first class honors) in 2021.

I enjoy exploring colors, shapes, structures in both physical and virtual worlds (and in their intersection). Check my resume for more information.

Side Projects

I like to get my hands on new technologies and do something fun with them. Here are a few of them I think you might like:

  • Bloggraph: A Hugo theme that powers this website; click here for a quick start guide.
  • TimeWalk: A coding metric tracker I use everyday, extensible, private, totally local. VSCode plugin available.
  • Slurmmy: Scripts that automate slurm jobs submission, maximize your slurm cluster usage.
  • Change: See white light dispersed through glass into colorful spectrum; the winning entry of the rendering competition of Advanced Computer Graphics 2023 at EPFL.

Hobbies

When I’m not scratching my head in the lab, I enjoy playing with my camera. I’ve been slowly and painstakingly organizing my photos into my photo website.

I also like playing guitar, boardgames and making cocktails (and drinking them).
