Hi there. I am a visiting scholar @ UC Berkeley, advised by Prof. Dawn Song. I study Large Language Models (LLMs), Agents, and Algorithmic Game Theory (AGT).

Outside research, I love anthropology, (non-fiction) writing, and composing / mixing music.

My current research interests:

  1. Are language models and agents sufficiently reliable? How can we design valuable mechanisms to ensure this, both theoretically and empirically?
  2. How does data really help the training process of language models and agents? Can we find valuable training dynamics or internal features that explain this?

Topics that may not be easy to get started in the short term, but I am still interested in:

  1. To what degree is it theoretically justifiable to anthropomorphize language models? To what extent can anthropological methodologies be applied to their study, and are there significant divergences between inter-model communication and human–model interaction?
  2. How do language models model language? Can interpretability tools reveal the representation of (even multimodal) linguistic concepts, and can the philosophy of language reshape our understanding?

If you are also interested in these directions and would like to collaborate, please contact me — or book a time to chat.

Teaching

I love teaching and have worked as a teaching assistant since the first semester of my sophomore year. I am doing my best to reduce inequalities in course teaching and help students from different backgrounds gain the same knowledge.

If you are my student (in SI 100B, SI 100+, or other courses) and want to chat for advice — though I am just getting started on many things myself — feel free to reach out anytime.

Collections

I enjoy exploring and creating music in different styles. Below are some pieces I have created in the past. If you also enjoy making music or are interested in research at the intersection of music and computer science, please contact me, and I would be happy to chat with you!
