Hello! I am Yuchen. You have reached my personal website.
I am a programmer, mathematician and free software advocate.
I did a PhD at the MASDOC program at Warwick, and spent two years in a postdoc position at CMSA at Harvard and another one and a half years at the KTH RMSMA group. My research was on probability and algebraic combinatorics.
After retiring from academia I worked as a full stack web developer for two years, writing C++, Python and Typescript, as well as occassionaly grilling people on algorithms and data structure (aka tech interviews).
As a free software advocate, I am an associate member and licensing volunteer of the Free Software Foundation, and a maintainer of GNU LibreJS and h-node.org. You can read about how I do my computing as a person on the freedom ladder. In my past academic life I also applied the philosophy of free software to knowledge and research. For example I shared my research in Robinson-Schensted algorithms as a wiki under a free Creative Commons license. I believe anyone can be an academic, seeking truth and sharing their findings with the public.
