Hi! Iām Yifan Zeng and my name in Chinese is ę¾äøå” . Iām currently a second-year Computer Science Ph.D. student at Oregon State University, where Iām fortunate to be advised by Huazheng Wang.
My research focuses on the robust planning and decision-making of large language models (LLMs). Iām passionate about developing Agentic AI through multi-agent systems, reinforcement learning, and preference optimization.
Before joining OSU, I worked as a Research Engineer at a technology startup, where I carried out AI solutions in the real-world using deep learning and computer vision. My previous research spans object detection, medical image analysis, self-supervised learning, and AI for science.
I received my B.Eng. in Data Science at Zhuhai College of Jilin University in 2023, ranking first in my department with a 3.84/4.0 GPA.
