I am an Assistant Professor at the School of Computer Science, University of Waterloo, where I am part of the WaterlooHCI lab. 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, where I was affiliated with the Dynamic Graphic Project (DGP) lab.

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., M.Math., and undergraduate students to work with me on exciting data-driven research. Please read this before contacting me.
