Short bio

I am currently an associate professor at the University of Lyon 2 and a member of the SID research team of ERIC laboratory. I received my Ph.D. in computer science from the university of Bejaia (Algeria) and the university Claude Bernard Lyon 1 (France) in 2016. I got a Magister degree from the university of Bejaia and an engineer degree in artificial intelligence from the university of Sétif in 2009 and 2006 respectively. My main research interests are secure data collection, key management in resource-constrained networks and graph database analytics for cybersecurity. I am looking for challenging issues related to the secure machine learning.
