Faculty & Permanent Research Staff
Thomas Heide Clausen, cand.polyt, PhD
Professor
A graduate of Aalborg University, Denmark (M.Sc., PhD – civilingeniør, cand.polyt), Thomas spent a number of years at INRIA where he, among other things, developed and standardised OLSR – the predominant routing protocol for community, mesh, and tactical networks.
In 2004 he joined faculty at Ecole Polytechnique, France’s premiere technical and scientific university, where he is currently a professor. He leads the computer networking research group, and enjoys working with with some of France’s best students.
Thomas has developed, and coordinates, the computer networking curriculum at Ecole Polytechnique, teaches several core classes therein. He’s the academic director of the elite and multidisciplinary Master of Science and Technology programme “IoT: Innovation and Management”.
In terms of research, Thomas is, particularly, interested in “keeping the Internet connected”, even when faced with the immense influx of “new devices” and “new uses”. Thus, his work has emphasized development of algorithms, protocols, and architectures for the (immodestly) termed “future internet”: the Internet of Things (IoT), personal-area networks (PANs), ubiquitous networks, rendering the current Internet routing more “robust” and “adaptive”, as well as for securely supporting new services across the Internet. Thomas has authored more than 100 peer-reviewed academic publications, which have attracted more than 16000 citations.
With a particular affinity for “applicable research”, Thomas remains an active contributor to standardisation. He served as co-chair of the MANET AUTOCONF working group from 2005 until its closure in 2012, within the Internet Engineering Task Force (IETF) – the international standardization body behind the Internet and behind protocols such as TCP/IP, HTTP etc. Also within the IETF, he has served on the Routing Area Directorate, an advisory group of routing experts providing final document reviews as part of the standardization process, as well as other expert advice on routing-related topics. Thomas has authored, edited, and contributed substantially to 24 published IETF standards. He has also consulted for the development of IEEE 802.11s, as well as contributed the routing portions of the recently ratified ITU-T standard G.9903 for G3-PLC networks – the international standard upon which, e.g., the SmartGrid/ConnectedEnergy initiatives are built.
Thomas maintains long-standing formal industrial research collaborations with, e.g., Hitachi (Japan), Fujitsu (USA), Toyota (Japan), Qualcomm (USA), EDF (France), ERDF (France), and Sagemcom (France). He also maintains close collaborative relations with peers in industry, including BAE Systems (UK), Cisco Systems (USA & France), and Alcatel-Lucent (France). He was involved in the ADEME “SOGrid” project, on the future French national “Smart Grid”. Thomas holds the Cisco endowed “Internet of Everything” academic chaire at Ecole Polytechnique.
Thomas is a senior member of the IEEE, and was named an “IEEE Computer Society Distinguished Contributor”, as part of the inaugural 2021 class.
Juan Antonio Cordero Fuertes, PhD
Assistant Professor
Juan Antonio Cordero is an assistant professor at École polytechnique. He graduated in Mathematics ("Licenciatura", M.Sc.) and Telecommunication Engineering (B.Sc.+M.Sc., "Ingeniería Superior") at the Universidad Politécnica de Cataluña (Technical University of Catalonia, UPC, Spain) in 2006 and 2007, respectively. He got his Ph.D. at École polytechnique in 2011, with a dissertation on the optimization of link-state routing protocols for operation in MANETs and compound (wired/wireless) Autonomous Systems. As part of his PhD, he participated in the development of OSPF for MANETs. Before joining faculty at École Polytechnique, Juan Antonio held postdoctoral research positions at the Université catholique de Louvain (UCL, Belgium) and at the Hong Kong Polytechnic University (Hong Kong SAR, People's Republic of China). He attained tenure at Ecole Polytechnique in 2020.
Juan Antonio's scientific interests include wireless mesh and mobile ad hoc networking, routing protocols and information dissemination algorithms, integration of wired and wireless networks, Internet measurements and future Internet architectures.
Kevin Jiokeng
Assistant Professor
Kevin Jiokeng is Assistant Professor at Ecole Polytechnique. He graduated from the Master of Engineering of Ecole Nationale Supérieure Polytechnique (Yaoundé, Cameroon) in 2017 and obtained his PhD degree in Computer Science and Telecommunications in 2022 at Toulouse INP (Toulouse, France), with his research works on emerging indoor localization technologies and heart activity based biometric authentication.
Kevin held a Postdoctoral Researcher position at Inria Lille (Lille, France) and a Research Engineer position at IRIT (Toulouse, France), in 2022 and 2018, respectively. He joined Ecole Polytechnique as faculty in 2022.
Kevin's research interests are wireless networks and ubiquitous computing with applications to localization technologies, wireless sensing, smart environments and cybersecurity.
Distinguished Affiliated Researchers
Jean-Louis Rougier
Professeur Chargée de Cours
Jean-Louis Rougier is a full professor at Telecom-Paris, and an adjunct professor (Professeur Chargee de Cours) et Ecole Polytechnique.
He obtained his engineering diploma from TELECOM ParisTech (formely named ENST) in 1996 and Ph.D. in 1999. He then joined the computer science and networking department as PostDoc and then as an associate professor. Since then, he has been teaching and working on routing and traffic engineering in networks, in various projects and context (from Optical, IP to Wireless Networks). During his sabbatical, he joined the UCLA Network Research Lab, led by Prof. Mario Gerla (January to June 2011).
At Ecole Polytechnique, Jean-Louis is teaching computer networking courses -- from computer networking fundamentals, to advanced computer networking -- and is as part collaborating on several research projects co-supervising, presently, two PhD-students.
Postdoctoral Researchers
PhD Students
Maxence Elfatihi
PhD student
Maxence Elfatihi earned his Master's degree in computer science with honors from IMT Atlantique (formerly Télécom Bretagne), specializing in cybersecurity and cloud computing. His Master's thesis focused on the application of formal verification methods to enhance security in railway line controls. Currently, Maxence is pursuing Ph.D. research under the guidance of Thomas Heide Clausen and Juan-Antonio Cordero-Fuertes.
Guillaume Brochot
PhD Student
After graduating from Ecole Polytechnique ("Cycle Ingénieur") & University of Cambridge (Master degree in "Technology Policy"), Guillaume worked for 8 years in the private sector, first as a strategy consultant, then within several tech start-ups in financial & legal services sectors, across various roles, ending up as Chief Operations Officer within a LegalTech company.
In 2024, Guillaume decided to transition back into sciences and to enrol in a PhD at Ecole Polytechnique under the supervision of Thomas Clausen, Jean-Louis Rougier, and Erwan Le Pennec.
