Hello! I am Xudong Shen (沈旭东). Friends also call me Oliver. I am a 5th year Ph.D. student at National Univeristy of Singapore, advised by professor Mohan Kankanhalli. I am interested in both the technical approaches to address social issues in AI systems and the role of policy and regulation in making AI systems more beneficial to our society. With a particular focus on fairness, I have worked on gender discrimination in FinTech, general fair representation learning, and biases in large language models and text-to-image generative models. I can be reached at firstname.lastname@example.org.
I had the privilege of interning at Sea AI Lab in Singapore from 2022 to 2023. 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…
