I am a postdoc researcher in Mohamed bin Zayed University of Artificial Intelligence, Abu Dhabi, UAE, hosted by Ting Yu. I research on data privacy, with specific interests in differential privacy for data analysis and large language models. I obtained my PhD in CS from National University of Singapore, supervised by Xiaokui Xiao, in 2024. Previously, I did internships at Alibaba Group and SEA AI Lab. Previously, I obtained my BSc in CS from the Chinese University of Hong Kong in 2018. Other than publishing papers in differential privacy, I also participated in challenges held by NIST, and our team won the third place in the 2018 Differential Privacy Synthetic Data Challenge and the first place in the 2020 Privacy Temporal Map Challenge.
