👋 About Me

I am a fourth-year Ph.D. student in the ML program of Geogia Tech advised by Prof. Pan Li. Prior to that, I received my B.S. degree (Stat, Math and Computer Science) and my M.S. degree (Computer Science) both from Purdue University.

My research focuses on large language models, AI agents, and trustworthy machine learning, with a particular focus on structured information, including graph- and network-structured data, time series, etc.

Specifically, my work spans topics in two main directions:

  • LLMs and AI Agents: multi-agent system, KV-cache manipulation, post-training, context management, and agentic data analysis.
  • Trustworthy ML: domain adaptation, out-of-distribution generalization, test-time adaptation and robust fine-tuning of foundation models, for reliable graph/geometric learning.

Also, I am currently open to full-time and internship opportunities. Please feel free to reach out about any relevant opportunities!
