I am an Associate Professor and the Director at the School of Information Technology, York University. I direct the Intelligent Visualization Lab funded by the Canada Foundation for Innovation (CFI) and Ontario Research Funds (ORF). I am a member of the Graduate Faculty for both the Department of Electrical Engineering & Computer Science and the School of Information Technology. Before joining York University I was a postdoc in the HCI group at Stanford University, where I worked with Maneesh Agrawala.

My research focuses on combining information visualization and human-computer interaction with natural language processing to address the challenges of the information overload problem. More specifically, I focus on devising novel visual analytics techniques to explore large datasets such as online conversations as well as understanding the utility and potential trade-offs of such techniques from the real user’s perspectives.

I received my Ph.D. in Computer Science from University of British Columbia, under the supervision of Giuseppe Carenini. Prior to that, I completed my M.Sc. degree at Memorial University of Newfoundland under the supervision of Orland Hoeber and Minglun Gong. I have conducted research on visual analytics at Tableau Software and the Qatar Computing Research Institute. My work has appeared in top journals and conferences including IEEE Transactions on Visualization and Computer Graphics, ACM Transactions on Interactive Intelligent Systems, ACM CHI, ACM IUI, ACM UIST, EuroVis, and ACL.

My research has been supported by Natural Sciences and Engineering Research Council (NSERC) of Canada, Canada Foundation for Innovation and National Research Council Canada among others.

Recent Projects

Natural Language Interactions with Visualization

The goal this research is to bring together the fields of information visualizations and HCI with NLP to enable a diverse range of users with different levels of skills and backgrounds to explore and analyze data faster and more effectively through natural and fluid interactions.

Visual text analytics for online conversations

In this line of research, the goal is to tightly integrate natural language processing and information visualization techniques to support the user’s task of exploring and analyzing conversations.

User-Adaptive Information Visualization

This project explores how user characterstics impacts on visualization effectiveness and how can a visualization adapt to such characterstics.
