Zhaotian Weng

Hi! I am a first-year phd student in Computer Science at the University of California, Santa Barbara working with Professor Eric Xin Wang. My research interests lie in Natural Language Processing (NLP), with a particular focus on multimodal models, and agents.

Before joining UCSB, I earned my Master’s degree with honors from the University of Southern California, where I had the privilege of collaborating with Professors Jieyu Zhao and Kuan-Hao Huang. Prior to that, I graduated with honors from Tsinghua University, where I was recognized as an outstanding undergraduate.
