Yuan Guo （郭源）

Senior Undergrad @ SJTU

📍 Singapore | Shanghai

I am a senior undergraduate in Yongqiang honors class of computer science, School of Computer Science, Shanghai Jiao Tong University. Currently, I’m visiting xML lab in National University of Singapore. I’m also working with FellouAI on building next-gen agentic browser. Prior to this, I spent a great time with Zhuosheng Zhang in SJTU and Ming Zhou(ACL Fellow) at Langboat Technology.

My research interests broadly lie in Natural Language Processing, Large Language Models, and their interdisciplinary applications. Recently, I have been focusing on computer-using agents and agent safety.

I have received the National Scholarship of the People’s Republic of China (awarded to the top 0.2% of students nationwide), the Fan-Xuji Scholarship at SJTU (awarded to 15 outstanding undergraduates annually), as well as the SJTU Academic Scholarship and the Yongqiang Encouragement Scholarship. I have earned straight A grades in all undergraduate courses related to mathematics and physics, and I’m a member of Fan-Xuji and Rongchang alumni associations.
