I am currently a post-doctoral researcher at the Aviz team of INRIA Saclay, Paris. I am part of the Microsoft Research INRIA Joint Center.

I previously worked at the LABRI as a member of the team GRAVITE of INRIA Bordeaux, where I prepared my PhD in Computer Science focused on graph comparison.

I am currently working on the developement of visualization and interaction tools designed to help for group awareness (as a member of the REACTIVITY project).

Ongoing research projects

Keeping track of Document Evolution by Animating Diffs

An important activity in collaborative writing is communicating about changes to text. The current tools we have at our disposal of to keep track of changes between two versions of a document are either based on side-by-side views of the two versions highlighting the differences between them; or present a visual merging of the two document versions, highlighting the diff edit operations using colors or other visual indicators (e.g. text that has been removed is in red or crossed on). Such tools are very effective when comparing two revisions of a document but they fail to represent the history of edits for more than two steps. In this project, we propose an animation technique for smoothly transitioning between different text revisions we included in a full system. The system supports rapid exploration of revision histories by combining text animated transitions with simple navigation and visualization tools.

WikipediaViz: Conveying Article Quality for Casual Wikipedia Readers

As Wikipedia became one of the most used knowledge base worldwide, the problem of the trustworthiness of the information it disseminates has become central, especially when considering casual readers that may not be aware of the online encyclopedia principle (anyone can edit, volatile information, etc.). With WikipediaViz, we introduce five thumbnail visualizations that aim to keep casual Wikipedia readers aware of important information about the articles they read and to raise potential quality issues.

A System for Exploring Multivariate Social Networks Social networks collected by historians or sociologists typically have a large number of actors and attributes. Applying analysis algorithms to these networks produces additional attributes such as degree, centrality, and clustering coefficients. Understanding the effects of this plethora of attributes is one of the main challenges in multivariate social network analysis. We have developed a tool to facilitate multivariate social network analysis. The system is designed to be a simple visualization tool, based around a comprehensive approach to visualize attributes. We support a large set of social analysis tasks by proposing several intuitive interactions to help in exploring the social network.

An Infrastructure to Compute and Maintain Aggregated Information for Group Awareness in Wikipedia Wikipedia fails to provide simple ways to gather information about the evolution of the encyclopedia: people are spending a lot of time in gathering information she needs to keep track of the editing process. The goal of this project is to provide a software infrastructure to compute and maintain aggregated information required to inform Wikipedians about contributors and articles. The situation of Wikipedia is quite specific, due to the explicit lack of hierarchy in Wikipedia and the openness of the system. However, similar situations will arise soon in other domains such as biology and chemistry where very large databases are maintained and enriched by organizations that can no longer keep with the pace of changes.
