I am currently a principal researcher of Huawei Hong Kong Research Center. I recevied my PhD in 2025 from the Chinese University of Hong Kong advised by Professor Sibo WANG. Previously, I obtained my Bachelor degree from ACM Class at Shanghai Jiao Tong University in 2021.

My research interests include algorithms for big data analytics and processing. I am always open for possible collaborations, please do not hesitate to contact me if you are interested!
