I am currently an Assistant Professor in 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 National University of Singapore. I am a recipient of the 2021 VLBD Best Research Paper Award and the 2022 SIGMOD Research Highlight Award. Broadly speaking, my research aims to develop efficient algorithms and systems for large-scale data management and analysis. I am also a member of Database Research Group at HKBU.

I am looking for Ph.D. students, research assistants, and visiting students. Please drop me an email, if you are interested.
