About Me

I am a tenure-track associate professor in the School of Data Science and Engineering, East China Normal University. Before joining ECNU, I was a postdoctoral researcher in the Department of Computer Science, University of Helsinki (work with Assoc. Prof. Michael Mathioudakis). My research interest lies in both the theoretical and practical aspects of data management, data mining, and machine learning. In particular, my recent studies focus on data stream algorithms, data management for machine learning, algorithmic fairness, and graph mining.
