About Me : )

Heyyy! I am Xudong Shen (沈旭东). Friends also call me Oliver. I am a 4th year Ph.D. student at National Univeristy of Singapore, advised by professor Mohan Kankanhalli, as well as a part-time research intern at the Sea AI Lab. I am interested in fairness and other safety problems of ML applications. I have worked on fair representation learning, gender discrimination in FinTech, and biases in large language models. And I can be reached at xudong-shen@u-nus-edu (replace hyphens with dots).

Between 2015 and 2019, I was an undergraduate at Zhejiang University, China, majoring in Naval Architect and Ocean Engineering. During this period, I explored various topics including computational fluid dynamics, satellite imaging, and policy research. My cv is here.

I believe in Diversity, Equity & Inclusion. I am committed to uphold these values.

If you are interested, I’ve written something more about myself…
