Research Projects

• USENET    [UseNet Website]
  
  UseNet is a European ITEA project, started in September 2007 for a period of 2 years. VTT (Finland), IKERLAN FAGOR (Spain), Alcatel (Belgium), Thales, BULL and LAAS-CNRS (France) are partners in this project. Its scientific goal is to define pervasive environments to improve the communication and intelligent cooperation between machines and between users. I participated as a postdoctoral fellow in this project by establishing a survey on machine-to-machine technologies and the guidelines of a self-adaptive Machine-to-Machine middleware.
• SECAS    [1]
  
  The SECAS project (Simple Environment for Context Aware Systems) focuses on adapting applications to their utilization context (the environment and the preferences of the user, the used device...). Under this project, our goal is to develop a platform that makes applications adaptable to different utilization contexts. This adaptation concerns three components: data, services and presentation. In this area, researchers have focused on capturing the context and on its dissemination to the application. This project focused on the impact on context on applications after its capturing and dissemination. This project was the central theme of my P.H.D. thesis work. A prototype has already been developed for the validation of the architecture and the adaptation strategy that I defined in my PHD thesis work.
• SITRANS    [12]
  
  The main objective of the SITRANS project is to provide a software platform for managing microarray experiments driven by researchers in biology. In the scope of this project, I participated in the specifications, design and development of the platform.
• SEFAGI    [10]
  
  The SEFAG project (Simple Environment For Adaptable Graphical Interfaces) was the main job of my Research Master's degree in 2003. This project focuses on adapting user interfaces to multi-terminal environments. Its purpose is twofold: (i) allow users to describe their GUIs and automatically generate their corresponding code and (ii) make the code generation adaptable to several kinds of devices. These graphical user interfaces must interact with several remote web services (math, updating a database, uploading images ...). In the scope of this project, I specified, designed and developed a complete platform that allows the automatic generation of JAVA user interfaces that can be used on smart phones Personal Digital Assistants and standard PCs starting from a simple XML description.
• SICOM    [13]
  
  SICOM is a research project funded by the Rh�ne-Alpes region that consists in establishing an efficient information system intended to create, exchange and share medical information between practitioners in order to improve patients health care. My contribution in this project was to automatically generate medical GUIs that are adaptable to many types of users (patients, specialists, nurses...) and several types of devices.
