Mentored Research

I’ve have the privellage of mentoring many amazing undergraduates in research projects since Spring 2024. Below are some of my most common areas (and I’m looking to expand this by a lot). If you’re interested in a project please let me know chang314@g.ucla.edu.

Multiplayer Bandits
We study the information asymmetry mutliplayer bandits applied to various bandit problems. One of my top students wrote a blog on this after he submitted the Cascading paper. See here for more details.
