About

I am a Ph.D. candidate from Huazhong University of Science and Technology (HUST) in China. I have been an internship at Tencent Inc. as part of the Intelligent Cloud Storage Joint Research center of HUST and Tencent. Currently, I am a visiting Ph.D student at the Center for Data Science at New York University. My research focuses on using Artificial Intelligence (AI) for data management and storage systems.
