what is going on?

11/2013 - Invited Panelist - Using the Internet to enhance scholarship and improve dissemination.
Georgetown University Library. Scholars from different disciplines discuss ways to improve dissemination of scholarship using the Internet. We also debate the changing landscape of scholarly work.


9/2013 - Awarded NSF Interdisciplinar Grant
Martin, Collmann, and Singh are awarded $300K NSF grant - Forecasting the Break: Building Community and Capacity for Large-scale, Data-Intensive Research in Forced Migration Studies. This is a new project to explore using big data for early warning of forced migration. Woohoo Again!!


7/2013 - CS4HS Workshop for high school teachers
We just finished hosting a three-day hands-on workshop for STEM middle school and high school teachers in the Washington, D.C. area. The workshop provided an introduction to the Raspberry Pi hardware, the Raspbian operating system, and the Scratch and Python programming languages. The teachers, student volunteers, and organizers were awesome. Thanks Google for the support!


4/2013 - Invited Panelist - Big data: Educating the next generation.
Interesting panel hosted by McDonough School of Business - very different perspectives of directions to take and what the core of big data education should include.


1/2013 - Award Begins
Singh, Sherr, and Yang awarded $500K NSF grant - Assessing Online Information Exposure Using Web Footprints. Woohoo!!


12/2012 - Best Paper Award
Sharara, Singh, Getoor, and Mann win best paper award at SocialInforamtics 2013 for paper entitled "Stability vs. Diversity: Understanding the Dynamics of Actors in Time-varying Affiliation Networks".



Most networks contain embedded communities or groups that impact the overall gathering and dissemination of ideas and information. Within these groups are individuals that are important or prominent because of their active participation over time. In this paper, we introduce a new method for identifying actors with prominent group memberships in time-varying affiliation networks. We define a prominent actor to be one who participates in the same group regularly (stable participation) and participates across different groups consistently (diverse participation), thereby having a position of structural influence in the network. Our measures for stable and diverse participation are tunable according to the underlying semantics for group participation and the level of impact of an actor’s history on his or her current behavior. We illustrate the semantics of our measures on both synthetic and real-world data sets with varying temporal connectivity structures. We also illustrate their utility by demonstrating their complementary behavior when compared to existing centrality measures.

5/2012 - Congrats Aditi!!
Aditi Ramachandran wins best student paper award at PST 2012 for paper entitled "Exploring re-identification risks in public domains"



While re-identification of sensitive data has been studied extensively, with the emergence of online social networks and the popularity of digital communications, the ability to use public data for re-identification has increased. This work begins by presenting two different cases studies for sensitive data reidentification. We conclude that targeted re-identification using traditional variables is not only possible, but fairly straightforward given the large amount of public data available. However, our first case study also indicates that large-scale re-identification is less likely. We then consider methods for agencies such as the Census Bureau to identify variables that cause individuals to be vulnerable without testing all combinations of variables. We show the effectiveness of different strategies on a Census Bureau data set and on a synthetic data set.
