About

This is the home page of Ryan Joo. I am a high-school student currently studying for my A Levels in Singapore, a recipient of the ASEAN Scholarship offered by the Ministry of Education of Singapore. A complete CV is available here.

I love participating in mathematics olympiad competitions and I am currently exploring university-level mathematics (and some physics).

You can read some of my publications and projects, some writings on olympiads, notes I have taken in school, as well as random topics that interest me under my blog. The source code for all my projects and writings can be found on my GitHub.
