Hi👋, I’m Tianjian! I’m a PhD student in Computer Science at Johns Hopkins University, proudly advised by Prof. Daniel Khashabi. Previously, I completed my Master’s degree in Computer Science at JHU, where I had the privilege of working closely with my wonderful advisors, Kenton Murray and Philipp Koehn. Before that, I was an undergraduate at New York University.

My research lies at the intersection between machine learning and natural language processing.

I prefer solutions that are simple, generalizable, and theoretically sound.

If you have anything to share with me, please feel free to contact me through my email: tli104 at jhu.edu
