#+title: Yuchen Pei
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 [[https://warwick.ac.uk/fac/sci/masdoc][MASDOC program at Warwick]], and spent two years in a
postdoc position at [[http://cmsa.fas.harvard.edu][CMSA at Harvard]] and another one and a half years
at the [[https://www.math.kth.se/RMSMA/][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 [[https://fsf.org][Free Software Foundation]], and a maintainer of [[https://www.gnu.org/software/librejs/][GNU
LibreJS]] and [[https://h-node.org][h-node.org]]. You can read about [[file:./my-computing.org][how I do my computing]] as a
person on the [[https://fsf.org/campaigns/campaigns-summaries#ladder][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 [[https://toywiki.xyz][wiki]] under
a free Creative Commons license. I believe anyone can be an academic,
seeking truth and sharing their findings with the public.
I can be reached at: xU)U1M2fEQL6bfYGpwSG (PGP key: [[/assets/ypei-pubkey.txt][47F9 D050 1E11
8879 9040 4941 2126 7E93 EF86 DFD0]]). Feel free to email me, whether
you know me or not. I am also [[file:./teatime.org][open to meeting up virtually over tea]].
