I  was born on the 12.th of November 1977 in El Biar, Algiers Algeria and grew up in Chlef  (ex. El Asnam) a beautiful town between Oran and  Algiers. Since 1994 I have been studying at the National Institute of Computer Science, (INI) Algiers Algeria . Then I passed through the Graduate School in Computer Science at EPFL. Now I'm PhD student and research assistant in the Pervasive and Artificial Intelligence group at the university of Fribourg. Currently I'm involved in the CB_SeC project which is a  subproject of the header project of  the PAI and Telecom groups, Welcome (or When Immersion Meets Intelligent  Networks ). My current fields of interest include distributed computing on the web,  ubiquitous computing, and context-aware computing.
