Data algorithms ยท AI systems

I am currently an Assistant Professor in the Department of Computer Science at Hong Kong Baptist University, and leading the LAGAS group. 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. My research focuses on developing big data algorithms and AI systems. I am also affiliated with Database Research Group at HKBU.
