A picture taken when I live in Purdue

Welcome

Hi~ I am Yizhen Yuan. I am currently a Ph.D. candidate at Tsinghua University in Beijing, China, and fortunately advised by Professor Liu, Yunxin and Professor Li, Yuanchun. I completed my undergraduate studies at Purdue University in West Lafayette, U.S .

I am interested in LLM Security, Privacy and Reliability. This is also the section I am responsible for in the paper Personal LLM Agents.

Thanks

When I come in to Purdue, Professor Turkstra have set up a good value as a computer scientist for me. When I took CS 397 (Honor Seminar), Professor Berkay chose me to do project with him amoung a lot of Computer Science Honor students. When I took CS 381 (Undergrad Crypto) and CS 580 (Grad Algorithm), Professor Blocki helped me a lot even with some material not covered in classes. During the following winter break, Professor Benotman helped me with my project. I also have received help from Professor Xiangxiong Zhang, Professor Jean Honorio, Tiantian Qin, Professor Kihong Park, Melanie and Professor Maji. Thanks them a lot. Without them, I will not be confident and enegetic in studying.

During the COVID pandemic, I came to Tsinghua University. It is my fortunate to meet Professor Liu, Yunxin and Professor Li, Yuanchun. They are kind and friendly professors. They helped me a lot when I started my first paper, and encouraged when my peers all have paper published. I will suggest all my CS friends to study here. Even if they are not professors, I would like to be friends with them.

Education

Graduate - Tsinghua University, Beijing, China

Major in Electronic Engineering . Belongs to Institute for AI Industry Research (AIR). Advised by Professor Liu, Yunxin and Professor Li, Yuanchun.
