I'm an assistant professor in the Department of Computer Science and Engineering, College of Engineering at the University of Notre Dame. I joined the faculty in August 2017, after completing my Ph.D. in Computer Science and Technology at Tsinghua University in 2015 and two-year postdoctoral training in Computer Science at the University of Illinois at Urbana-Champaign. [C.V.]

My research focuses on data-driven user behavior modeling for applications such as future behavior prediction, social recommendation, fraud detection, event summarization, mission planning, and effective teaching. It is at the intersection of social media analysis, network science, text mining, information extraction, spatiotemporal data mining, machine learning, and artificial intelligence.
