Yuzhe (Toby) Yang

Hi, I am Toby Yang, also go by the name Yuzhe Yang (阳雨哲). I am currently a final-year undergrad at The Chinese University of Hong Kong, Shenzhen, majoring in Computer Science and Engineering. During my undergrad studies at CUHK-Shenzhen, I have been fortunate to be advised by Prof. Benyou Wang and to collaborate closely with Prof. Honghai Yu’s team at Nanjing University. I was also a member of TheFinAI, led by Jimin Huang. Prior to that, I had the opportunity to work with Prof. Jianfeng Mao.

My vision is to build reliable and trustworthy AI systems that bridge the gap between machines and the real world. My focus is on enabling (vision) language model to interact more reliable with humans and their environments, empowering them to understand and simulate the underlying principles of the world. Additionally, I strive to uncover the internal mechanisms of language model to demystify their "black-box" nature, making AI system more interpretable, transparent, and aligned with human values. Through my research, I hope to contribute to the development of AI systems that are not only intelligent but also responsible, ethical, and deeply integrated into our daily lives.

Currently, I am seeking a PhD position. I am also open to research collaborations. If you are interested in my work or would like to discuss potential collaboration opportunities, please feel free to reach out and schedule time with me.
