Zhan Ling

I am currently a Research Scientist at ByteDance, focusing on enhancing the tool-use capabilities of LLMs. I have received my Ph.D. at UC San Diego , advised by Prof. Hao Su. I have previously interned at Qualcomm and X, the Moonshot Factory. Before starting my Ph.D., I received my B.E. in computer science from Yao Class at Tsinghua University.

Research interest

My long-term research interests lie in developing intelligent agents that can solve challenging problems and continually improve through interactions. I have extensively explored diverse areas such as imitation learning, reinforcement learning, robotics, and reasoning. Currently, my primary goal is to create an reasoning agent capable of achieving superhuman performance on challenging problems.
