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.

Research Experience

Prior to the start of my PhD, I also had great chances to explore various topics in computer science.

During my internship at IST Austria, I was working on an algorithm that transform images into embroidery patterns in real life via a programmable embroidery machine.

Starting from my final year at CUHK, I worked with Prof. Fu Chi Wing on my graduation project. We studied the design and optimization of the structural rigidity of assembly structures. The project was later extended to a paper published at Eurographics 2022.

I also worked on a few other short-term research projects before I stepped into the world of graphics, including exploring computationally efficient neural networks with Prof. Anand Sarwate at Rutgers, funded by Professor Charles K. Kao Scholarship; generating adversarial samples in natural language processing with Prof. Michael Lyu; and a project about information theory with Prof. Sidharth Jaggi.

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 boardgames and making cocktails (and drinking them).
