About

I'm Linrong Cai/ Chris Cai, a rising senior Math and CS undergraduate at University of Wisconsin Madison. My research interest is Machine Learning and Optimization, and I am doing research study under Professor Frederic Sala and Professor Jelena Diakonikolas. I have a strong interest in math, and have finished courses related to Analysis, Measure Theory, Probability, Combinatorics, Abstract Algebra at UW-Madison. Among them, my favorite topic is Analysis and Probability Theory. I am fortunate to worked with Dyah Adila, Nicholas Roberts, and Nikos Zarifis at UW-Madison.

Check the Recent Honor Paper about Cantor Set I wrote for my math analysis courses advised by Professor Jordan Ellenberg, though it is mostly Number Theory.
I like traveling and hiking. Some famous National Parks that I've visited are Yosemite, Yellow Stone, Grand Canyon, Rocky Mountain.
I like math a lot. I spent quite some time playing with contest like math problems during high school.


CLRT19 is short for Cai Lin Reuleaux Triangle 19, with Cai Lin as my name, reuleaux triangle is one of my favorite shape, 19 is a number that I like. Fun fact: Every Natural Number can be represented by 19 fourth powers, and the problem related to it is called Waring's Problem.
