In collaboration with Dr. Arlene Chung from the UNC School of Medicine, David Gotz is part of a newly awarded a 3 year RO1 NIH grant which has been awarded through the joint NSF/NIH QuBBD program. This approximately $1 million grant is the VACLab’s second QuBBD award, following a planning grant awarded by NSF in 2015 (to a different team, exploring a different topic).
With UNC as the lead institution, this new award will fund an aggressive mobile health project that pulls together a team of new collaborators from Harvard, Pittsburgh, and UNC.
Building on our award-winning methods for externalizing selection bias within the Tempo visual analytics system (which won Best Paper at ACM IUI), a follow-up article has now been published in ACM Transactions on Interactive Intelligent Systems. This collaborative project with the UNC Lineberger Comprehensive Cancer Center expanded on the original paper with more details and an initial evaluation with a use case and analysts from the UNC Lineberger Cancer Surveillance System (CIPHR, formerly known as ICISS).
The IEEE VIS conference will take place in Phoenix in just over a week. VACLab research will be represented at IEEE VIS in a number of ways.
Two IEEE TVCG papers will be presented as part of IEEE VAST, both the result of collaborative work with other universities. These include:
* **RCLens: Interactive Rare Category Exploration and Identification** Authors: Hanfei Lin, Siyuan Gao, David Gotz, Fan Du, Jingrui He, and Nan Cao * EventThread: Visual Summarization and Stage Analysis of Event Sequence Data Authors: Shunan Guo, Ke Xu, Rongwen Zhao, David Gotz, Hongyuan Zha, and Nan Cao
We’ve recently published a new article focused on research gaps in routine health information system design barriers to data quality and use in low- and middle-income countries. The article has been published in the International Journal of Health Planning and Management, and is now available “online first” from journal’s website.
Lead by CHIP PhD student Manish Kumar, also of the UNC MEASURE Program, the article presents the results of a literature review and argues for adopting an increased focus on systems thinking during health information system design.
ACM Computing Reviews publishes an annual list of “Notable Items” from the field of computing as part of a feature that it calls the “Best Of Computing.” recently released its 21st annual Notable listing, which honored just 231 books and papers selected from across the full breadth of computer science.
I’m happy to share that our 2016 ACM Intelligent User Interfaces (IUI) paper, which was honored with the IUI Best Paper award, was named one of the 231 items named in the 2016 Notable list.
I’m excited to announced that I’ve secured a 4 year $1M+ grant from NSF for a new 4-year research initiative. In this project, my team will designing, develop, and evaluate a set of Contextual Visualization Methods for exploratory data analysis which are designed to support the discovery of more robust and generalizable insights from high-dimensional data. More specifically, this project is exploring new techniques for detecting, communicating, and reducing the impact of selection bias and other threats to validity which can arise during interactive visualization-based data analysis.
IEEE Transactions on Visualization and Computer Graphics (TVCG) just published a paper I wrote collaboratively with a number of colleagues on Rare Category Visualization. The paper is now available online and will appear eventually in a print issue of the journal. Here is the abstract from the paper:
Rare category identification is an important task in many application domains, ranging from network security, to financial fraud detection, to personalized medicine.
Congratulations to VACLab member Rashnil Chaturvedi who is part of the UNC team that was recently named a Finalist for the 2017 INFORMS O.R. & Analytics Student Team Competition.
To quote the competition website, “Eight student teams from around the world have been selected as finalists in the inaugural INFORMS O.R. and Analytics Student Team Competition. INFORMS, the leading international association for professionals in operations research and analytics, introduced this new competition to highlight young talent and provide O.
The journal Information Visualization has made our new article “Z-Glyph: Visualizing outliers in multivariate data” available online as of February 14, 2017. You can download the paper from the Sage website by following this link. The paper describes work done in collaboration with Nan Cao (Tongji University), Yu-Ru Lin (University of Pittsburgh), and Fan Du (University of Maryland).

I recently served as a Guest Editor for a special issue of IEEE Transactions on Multimedia focused on Visual Analytics in Multimedia (Volume 18, Issue 11, 2016). The issue was published at the end of the year and included several exciting papers on a broad range of topics.
To frame the issue, my co-editors and I authored an editorial titled “Visual Analytics in Multimedia—Opportunities and Research Challenges. In addition, we co-authored a survey article describing the state of the art in visual analytics of social media data.
