Thomas Heide Clausen, cand.polyt, PhD

A graduate of Aalborg University, Denmark (M.Sc., PhD – civilingeniør, cand.polyt), Thomas has, since 2004 been on faculty at Ecole Polytechnique, France’s premiere technical and scientific university.

At Ecole Polytechnique, Thomas he holds the Cisco-endowed “Internet of Everything” academic chaire, and leads the computer networking research group. He has developed, and coordinates, the computer networking curriculum,  co-coordinates the Masters program in “Advanced Communication Networks” (ACN) and directs the Gradaute Degree Program Connected Objects for a Digitized Society.

Thomas has published more than 80 peer-reviewed academic publications (which have attracted more than 12000 citations) and has authored and edited 24 IETF standards, has consulted for the development of IEEE 802.11s, and has contributed the routing portions of the recently ratified ITU-T G.9903 standard for G3-PLC networks – upon which, e.g., the current SmartGrid & ConnectedEnergy initiatives are built. He serves on the scientific council of ThinkSmartGrids (formerly: SmartGridsFrance).

Juan Antonio Cordero Fuertes, PhD : Research Assistant Professor

Juan Antonio Cordero Fuertes, PhD

Research Assistant Professor

Juan Antonio Cordero is a research 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).

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.

Jiazi Yi, PhD : Research Engineer

Jiazi Yi, PhD

Research Engineer

Jiazi Yi joined the Network Research Group of Ecole Polytechnique in 2010 as a postdoc researcher, and is currently a research engineer in the group. Jiazi got his Ph.D from University of Nantes, in 2010, a M.Sc. in Electronic System from Polytech’Nantes (France), and a M.Sc. in Computer Science, South China University of Technology.

Jiazi's scientific interests include mobile ad hoc networks, smart grid, routing protocols, sensor networks, long range and low power networks, QoS, etc. His PhD thesis focuses on the multi-path routing protocol for ad hoc networks, in which MP-OLSR was proposed. He has published above 30 peer-reviewed publications and co-authored several international standards. He is also one of the main contributors of LOADng routing protocol, which is the default routing mechanism used in G3-PLC for the future smart grid now being deployed in France and allover the world.

Currently he is also teaching/coordinating 3 classes at Ecole Polytechnique: INF474X (Modal-Cybersecurity), INF557 (Introduction to Network Architectures - TD) and INF667C (ACN-M2 Scientific project).

W. Mark Townsley

Professeur Charge de Cours, Cisco Fellow & Vice President

Mark joined Cisco in 1997 as a software engineer, focused on remote access and tunneling protocols in Cisco’s IOS, as well as scaling of the core IOS virtual interface system to support the rapid growth of dial-up and broadband connectivity in the 1990s and early 2000s. Mark is well-known in the Internet Protocol community as well, twice-nominated for terms as IETF Internet Area Director (2005-2009), Layer 2 Tunneling Protocol (L2TP) Working Group Chair (1999-2005), Internet Engineering Steering Group (IESG) Liaison to the Internet Architecture Board (IAB), IETF Pseudowire Working Group Technical Advisor, and is currently co-Chair of the IETF Home Networking Working Group (Homenet). On faculty at Ecole Polytechnique in Paris, Mark also serves as “Professeur chargé de cours”, teaching and mentoring some of the brightest undergraduate and graduate engineering students in France. Before Joining Cisco, Mark held engineering and research positions at IBM, the Institute for Systems Research (ISR) and the Center for Satellite and Hybrid Communications Networks at the University of Maryland.

Mark holds a Bachelor of Science (summa cum laude) degree in Electrical Engineering from Auburn University and a Master’s degree in Computer Science (magna cum laude) from the Johns Hopkins University Applied Physics Laboratory.
