About me

I am a final-year Machine Learning Ph.D. student in the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign (UIUC), advised by Prof. Han Zhao and Prof. Bo Li. Previously, I obtained my B.S. in 2019 from UIUC with double majors in (1) Physics, (2) Statistics & Computer Science.

I have worked on multi-task learning, out-of-distribution (OOD) generalization, domain adaptation and meta-learning. Besides, I have adapted transformers to solve quantum computing problems in Amazon (Paper).

Lately, I have been focusing on foundation models (e.g., large language models and multi-modal models), improving their reliability and efficiency. I am currently interested in

  1. Improving the multi-task capabilities of foundation models (LLM and multi-modal models).
  2. Enhancing the controllability and reliability of foundation models by designing better alignment/RLHF methods.

I will graduate in summer 2024 and I am looking for full-time AI research scientist jobs in the industry!
