Shangqing Xu (徐尚青)
Bio
I'm a first-year PhD student of Computational Science and Engineering at Georgia Tech, advised by Prof. B. Aditya Prakash. I also work closely with Prof. Chao Zhang. Previous to my PhD study, I obtained my Master's degree in Computational Science and Engineering at Georgia Tech. Before joining Tech, I received my Bachelor's degree in Computer Science and Technology at Tsinghua University. In Tsinghua, I was fortunate to work with Prof. Wentao Han, Prof. Jie Tang and Prof. Dan Pei.
My ultimate research goal is to build self-evolving AI that can serve as active learner and make interactions with human and real world efficiently. My primary research focuses on machine learning and real-world NLP tasks:
- Data-efficient ML with self-supervision, ML4H 2023
- Large language models (LLMs) with external guidance, Arxiv preprint
- Multi-modality, NeurIPS'24
- ML theory, IJCNN 2020

Misc
If you are interested in how my name is pronounced in Chinese, it sounds like 'Shawn-Chin Shoo'.
I'm especially interested in reading novels. My favorites are Le Comte de Monte-Cristo and the Foundation series (which contributes to my research interest fairly a lot). Visual novel games are also of my preferences, among which I enjoy Steins; Gate and 13 Sentinels: Aegis Rim the most.
