I am currently an Assistant Professor with the Department of Computer Science at Hong Kong Baptist University. I earned a Ph.D. in computer science from Nanyang Technological University, followed by a postdoctoral stint at the National University of Singapore. I am a recipient of the 2021 VLDB Best Research Paper Award and the 2022 SIGMOD Research Highlight Award. Broadly speaking, my research focuses on big data science, which is to develop efficient algorithms and systems for large-scale data management, analysis, mining, and learning. I am also affiliated with Database Research Group at HKBU.
