I am an Assistant Professor at the School of Computer Science, University of Waterloo. I am also a member of the Waterloo Artificial Intelligence Institute (Waterloo.ai). I received my Ph.D from the Department of Computer Science, University of Toronto. I was affiliated with the Dynamic Graphic Project (DGP) lab during my Ph.D. Before coming to University of Toronto, I received my B.Eng (with honour) drom the College of Computer Science, Zhejiang University, where I was also affiliated with the Chu Kochen Honors College.

My research focuses on the areas of Information Visualization (InfoVis), Human-Computer Interaction (HCI), and Data Science. I develop advanced interaction and visualization techniques that promote the interplay between humans, machines, and data. My research aims to boost the efficiency of real-world data analytical activities that involve a large amount of data, various complicated models, and a diverse group of analysts. I contribute to the design, development, and evaluation of visualizations that support the general data science workflow: from exploratory data analysis, then to model development and interpretation, and finally to insight communication and storytelling.

I am currently seeking highly-motivated and hard-working Ph.D. students, M.Math. students, and undergraduate interns to work with me on exciting data-driven research. Please read this before contacting me.
