Yuqi Yang (Aragorn)

I am a PhD student in Statistics at the Wharton School, University of Pennsylvania, and collaborate closely with Prof. Ying Jin. Before that, I studied Mathematics and Computer Science at HKUST, where I worked on conformal prediction with Prof. Xinzhou Guo and on cognitive science and intention understanding with Prof. Yangqiu Song at the KnowComp Group. In Spring 2025, I visited ETH Zurich.

During my undergrad, I also did internships in quantitative research at Hangzhou Wangdao, hedge fund research at Jihai Investment, and software development at Hundsun.

Misc

Outside of research, I go by Aragorn. It's a nod to my favorite movie series, The Lord of the Rings, and it's the name I've used ever since I first saw the films.
