PhD student at Georgia Institute of Technology

About me

Hello! Welcome to the homepage of Mengdie Hu!

I am a PhD student in the Human-Centered Computing program at Georgia Institute of Technology. I am a member of the Information Interfaces research group. My advisor is Dr. John Stasko.

Before joining Georgia Tech in 2009, I did my Bachelor's at Peking University, Beijing, China. As an undergraduate student, I worked with Dr. Xiaoru Yuan in Peking University's Visualization and Visual Analytics Group.


I identify myself as a researcher in the Human Computer Interaction community with special interests in information visualization and visual analytics. My research focuses on text and network visualization, especially when applied to the business domain and social media analysis. Over the past couple of years, I have been developing dotlink360, a visual analytics system that helps analysts making sense of converging business ecosystems. More recently, in collaboration with researchers from Microsoft Research Asia, I have been working on using visual analytics for understanding public opinion and influence in social media. Our short paper on Twitter's role in breaking the news of Osama Bin Laden's death has been covered by Georgia Tech News Room, ReadWriteWeb, MSNBC, LA Times, Washington Times, American Public Media, Poynter Institute, and a number of other media outlets.
