Hongcheng Gao(高鸿成) is a second-year Master student at UCAS. He received his Bachelor's degree of Computer Science and Technology at Chongqing University in June 2023. In his undergraduate years, he was a research intern at THUNLP, advised by Prof. Zhiyuan Liu. In the early stages of his research, he worked closely with Yangyi Chen and received great help from him. Nowadays, he is advised by Zhijie Deng, Tianyu Pang and Chao Du at SAIL.

His research interests lie in trustworthy NLP, large language modeling and multi-modal learning.
