Some projects I have worked on:
FC² project (Fédération de Cercles de Confiance / Federation of
Circles Of Trust)
Partners: Orange, Gemalto, EADS, Telecom Paris Sud, CEV,
FC² is a French research project labeled by 2 competitive clusters, TES
and Sytem@tic. This project aims at promoting the use of digital
identity management technologies by developing use cases for a federated
identity management platform mixing e-banking, e-services and
- Participation in the specification working group (technical studies,
redaction and review of specification documents)
- Participation in the integration working group (design of the physical
architecture of the services developed by Atos Worldline)
The goal of this project is to investigate the impact of real-world
interfaces (NFC, RFID, 2D barcode...) on the use of social networks. This
project also studies the federation of the presence information spread
on multiple social networks and instant messaging services and its
advantages in terms of privacy management.
A video demonstration of this application is available
NFCSocial has been presented during the
IEEE NFC'09 workshop
W3C Workshop on the Future of Social Networks.
Presence: federation and contextualization
I investigated this research area through several labs and short range
projects. The goal of these labs was to build a federated vision of
the presence information, mapping the representation of this information
in the main instant messaging systems or social network services to the
presence model published by the IETF. After the constitution of this
federated model, the presence information can be enriched with
contextual information coming from a user's devices and environment.
This information can also be used in communication systems to enhance
the way people can be reached or to avoid unnecessary alerts and
Webphone / Webcontact
This project aims at developing a web component to allow a user to phone
anybody using his computer's microphone or webcam, without any
installation. The web component behaves as a generic IP phone on the
telecom network. On this project, I was responsible for the design of
the communication protocol between the web component and the server
part, and the communication of the service with the IP telecom network.
In the course of my (relatively short) career, I have had the opportunity
to present my work on various occasions.

I would like to write a PhD thesis on a topic related to networking:
routing, service connexion and invocation, alternative service
delivery architectures, network overlay, network modeling, high
availability mechanisms... I am quite open on the topic of this
thesis, yet I would particularly like to investigate the two following
Connection, composition, invocation and orchestration models for
In the recent years, the telecommunication world has seen the rise of
converged network architectures using the next generation network
paradigm. The IP Multimedia Subsystem is an architecture that applies
the NGN principles. In this architecture, services are connected using
a unified interface and the way they are triggered during a call is
managed through filtering criteria that decide whether services are
invocated in sequence, in parallel and their order. This model is
slightly different from the service composition model that are used
within the enterprise IT community which follows the SOA / BPM / BPEL
model and mechanisms. Those two models are examples of different
approaches regarding the way services are connected and called from
the underlying network.
With the ongoing move towards convergent services and the appearance
of new kinds of network architectures or network overlays, the models
used to connect, compose and orchestrate services need to be studied
in depth. Issues related to identity management, security, privacy,
customization, context awareness and interoperability will gain
importance as networks and their uses become ubiquitous.
Those are the issues I would like to investigate in my thesis.
Influence of mobile computing and of the technologies related to
the Internet of Things on urbanism
Mobile computing and networking has already changed the way people
retrieve information about their urban environment. Yet, we are only
at the beginning of the changes triggered by information and
communication technologies in cities. The boom of the Internet of
Things will lead to new uses that will impact the cities durably and
dramatically. In my thesis, I would like to investigate this impact,
and the relationship between the physical space and the information
space. This could be seen as a follow-up of the NFCSocial project.
