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, Entr'Ouvert
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 e-government.
- 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)
NFCSocial
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 here.
NFCSocial has been presented during the IEEE NFC'09 workshop and the 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 disruptions.
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.

Courses:

IP Multimedia Subsystem, course given in Telecom Lille 1, September 2010.

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 topics.

Connection, composition, invocation and orchestration models for connected services.

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.
