I am a postdoctoral researcher of Computer Science at University of Illinois at Urbana-Champaign working with Professor Jiawei Han.
My research focuses on Data-Driven Behavioral Analytics: behavior modeling and social media analysis. The methodology is from Observations to Representations to Algorithms. Problems I investigate vary from [slides] to [slides].
