Hi, nice to have you here!
I am Mark, a fourth-year computer science undergrad at University of Illinois Urbana-Champaign, supervised by Professor Jiawei Han. I am also collaborating with the Matsuo Iwasawa Lab.
My current research interests include:
- augmenting LLMs with external knowledge sources;
- turning LLMs/Agents via reinforement learning.

I like singing and photography, and I’m more of a cat person!
Feel free to reach out to me if you have any questions, want to discuss anything that sparks your interest, or schedule a coffee chat with me!
