Biography

Graduated in June 2009, I got my Engineering degree in Telecommunications Systems and Networks form National School of Applied Science (ENSA) of Tanger (Cameroonian-Moroccan Goverments Scholarship). The year after in August 2010, I received the MSc degree in Ubiquitous Networking and Computing at University of Nice Sophia Antipolis (UNS) (Master Program Grant). I was granted by The 2010 French Goverment MESR for a Ph.D. position in the team-project MAESTRO at INRIA Sophia Antipolis under the direction of Philippe Nain and Sara Alouf. From Sept. 1st 2013 to Nov. 1st 2013, I was a Visiting Research Scholar of Prof. Don Towsley at University of Massachusetts, Amherst in USA. I got my Ph.D. degree in Computer Science on the topics of Performance Evaluation of Caching Networks and Green Cellular Networks from University of Nice Sophia Antipolis on Feb. 2014. Until Dec. 2014, I was holding a Postdoctoral Research Fellowship at Orange Labs.

Since then, I'm currently holding a mid-senior Data Scientist position at Orange Business on the behalf of KLANIK CONSULTING
