Brown CS Continues Strong Levels Of VIS Participation

As VIS 2015 (the premier combined conference for advances in visualization, co-located with the VAST, InfoVis, and SciVis conferences) arrives in Chicago this week, Brown University’s Department of Computer Science (Brown CS) continues its strong level of representation and participation, with a faculty member and a PhD candidate each contributing papers to two separate conferences. As of this writing, the Guo/Gomez/Ziemkiewicz/Laidlaw collaboration "A Case Study Using Visualization Interaction Logs and Insight Metrics to Understand How Analysts Arrive at Insights" has just received an Honorable Mention award.

“As VIS has grown, our Graphics, Visualization, and Interaction group has grown with it,” says Professor David Laidlaw. “We’ve always had strong representation, and this year, we’re contributing our usual large volume of varied and intriguing research.” The full list of papers is below, with single asterisks indicating papers with Brown CS alum co-authors, and double asterisks indicating papers with Brown CS faculty members or current student co-authors:

"There’s a love of interdisciplinary work here at Brown CS and in our Graphics, Visualization, and Interaction group," David says, "and a lot of the success we’re seeing now just comes out of Andy’s and my toolsmithing, our sense of craftsmanship. We wanted the best people around us as we make great tools that scientists will use, and we still do."
