data to understand how people communicate, collaborate, what
information they exchange, what role they play in social
groups has been tremendously simplified with the popularity of
online networking systems such as Friendster, LinkedIn, or
Facebook. Compared to data collected through polls and
interviews, collected networks require less processing as they
are directly stored digitally and open new opportunities for
social scientists as they are far larger and often contain
much richer information. However, this avalanche of data
raises new challenges for their analysis: tools need to
support a very large amount of data often evolving through
time.</p>

human brain is particularly effective at processing visual
information, researchers in computer science developed a
number of visual exploration system to analyze graphs and
networks. In the last five years, an increasing part of the
research in information visualization focused on graph
visualization, tackling the problem from novel angles. Our
research focused on alternative representations to node-link
diagrams, supporting the analysis of denser networks as well
as novel interaction techniques to scale to larger datasets.
In this talk, I will present an overview of these novel visual
exploration systems.</p>

Microsoft Research since december 2008. Her interests lie in the
visual exploration of graphs and networks,<br>
visualization of groups, interactive graph navigation techniques
and evaluation methods for information visualization. She
completed her Ph.D on the visual exploration of social networks
in 2008, supervised by Pr. Jean-Daniel Fekete in France and Pr.
Peter Eades in Australia.</font></p>

involved in at MSR include the visualization of heterogeneous
networks (multiple types of nodes and edges), the visualization
of networks evolving over time, and taking advantage of natural
user interactions (sketch, natural language) to create
and interact with visualizations.</font></p>
