Welcome!

Hey there! I’m Shiwei, a senior math major at UC Berkeley. My main interests are broadly in applied mathematics, specifically machine learning. Previously, I was a software engineering intern at Heimdall Data, where I worked on caching and querying processes within the Heimdall proxy. In the past, I was also involved in competitive programming, and coached high school students to promote to the Silver and Gold divisions in the USA Computing Olympiad (USACO).

Aside from academics, I play piano, arrange music, and walk my pet Shibas for fun. I also enjoy performing music with The Intermission Orchestra at UC Berkeley. If you’re equally interested in any of the above, let’s chat! My email is aprilschen@berkeley.edu.

You can find various things that I work on around my website. Below are my coursework and some course notes I’ve taken, as well as links to projects and other miscellaneous fun things I’ve made over the years. Some pointers to things I think you’ll find interesting:

• My professional information, being my teaching and my resume.
• My repository of viewable personal projects.
• My project on Low-Rank Adaptation for my Linear Algebra class.
• My paper on Probability and Brownian Motion for my Measure Theory class.
• My blog, where I talk about topics important to me.
