Philippe Owezarski is a full time researcher of CNRS (the French center for scientific research), working at LAAS (Laboratory for Analysis and Architecture of Systems), in Toulouse, France. He got a PhD in computer science in 1996 from Paul Sabatier University, Toulouse III and a habilitation for advising thesis (HDR) in 2006. His main interests deal with high-speed networking and more specifically IP networks monitoring, and Quality of Service and security enforcement based on measurements.

From 1999 to 2001, he was on sabbatical leave, working for Sprint ATL in Burlingame, California. There he has been working on the Sprint monitoring IPMON project, and focused mainly on actual TCP flows analysis. Back to LAAS, Philippe Owezarski has been one of the main contributors of a monitoring project in France – METROPOLIS, has been leading a French steering group on IP networks monitoring, and has been leading the French MetroSec project aiming at increasing the robustness of the Internet against DoS and DDoS attacks. He has also been contributing to the European COST-TMA and ECODE projects which proposed to use monitoring as the main support for enforcing QoS optimization and security mechanisms in networks (in particular by using machine learning techniques for improving routing and anomaly detection). He then has been continuing this work in the framework of the European ONTIC project that aims at designing autonomous unsupervised analysis of traffic and anomaly detection mechanisms for big traffic data. Philippe Owezarski also uses monitoring and honeypots for studying malicious traffic in the Internet and assessing the threads on the network and its users. Last, Philipe Owezarski worked on the deployment of SDN technology on IXP networks for improving flexibility, scalability and security. This was done in the framework of the H2020 ENDEAVOUR project, and on the TouIX IXP. Since 2023, Philippe Owezarski is strongly involved in the French PEPR program funded by France 2030 on "5G and networks of the future" participating to two projects : NF-MUST and NF-HiSec.

Philippe Owezarski is the author of more than 100 papers in international journals and conferences, and he contributed to the writing of 7 book chapters. He is also the editor of 7 books, associate editor of the IEEE TNSM journal, JNSM journal, and was a member of the TMA steering committee. Philippe Owezarski has also been and still is the advisor for 18 PhD thesis and 3 post-docs. Philippe Owezarski was also the TPC chair for 17 conferences, including the CNSM’2012 conference, and ACNS’2014 congress.

From January 2016 to december 2019, Philippe Owezarski was the head of the “Network and Communication” department at LAAS, and as such member of the LAAS direction council. From january 2021 to march 2023, he was the head of the "Trustworthy computing systems and networks" department at LAAS. He was also from September 2016 to august 2021 a member of the section 6 (related to computer science) CNRS national council.
