Zixuan Wang

Hi! I am Zixuan (子轩) Wang, a third-year Ph.D. student in Electrical and Computer Engineering at Princeton University. I am fortunate to be advised by Prof. Jason D. Lee.

My research interests broadly lie in understanding the foundations of LLMs and deep learning, as well as leveraging both theoretical and empirical explorations to advance the frontiers of deep learning and language modeling.

I did my undergraduate study at the Institute for Interdisciplinary Information Sciences (IIIS), Tsinghua University, also known as Yao Class.

You can contact me at wangzx (at) princeton (dot) edu. My CV is here.
