I am Cheng Yang, a first-year PhD student from BergLab at the University of California San Diego, fortunately advised by Prof. Taylor Berg-Kirkpatrick.
Prior to UCSD, I earned my master’s degree from Tsinghua University, advised by Prof. Yujiu Yang and bachelor’s degree from Central South University. My research trajectory has been greatly enriched by opportunities to work with Prof. Junxian He on LLM agents and with Prof. Lemao Liu on machine translation.
Currently, I am interested in Training and Evaluating MLLMs Agents for applications under various scenarios.
Listed are my first and co-first author papers; see my Google Scholar profile for the full list.
