  • Mathématiques Supérieures / Mathématiques Speciales, Lycée Louis-le-Grand, Paris, France (1990-1992)



Thierry E. Klein leads the "BHAG" lab which implements innovative solutions created from disruptive research ideas in Nokia Bell Labs.

He formerly led the Network Energy Research Program at Bell Labs, Alcatel-Lucent leading a team of researchers, engineers and scientists across multiple research domains and locations with the mission to conduct research towards the design, development and use of sustainable future communications and data networks. His team is based in Murray Hill, Crawford Hill, Stuttgart, Villarceaux and Dublin. He also serves as the Chairman of the Technical Committee of GreenTouch, a global consortium dedicated to improve energy efficiency in networks by a factor 1000x compared to 2010 levels.

He joined Bell Labs Research in Murray Hill, New Jersey in 2001 and has been conducting fundamental and applied research on next-generation wireless and wireline networks, network architectures, algorithms and protocols, network management, optimization and control. From 2006 to 2010 he served as the Founder and CTO of an internal start-up focused on wireless communications for emergency response and disaster recovery situations within Alcatel-Lucent Ventures. Thierry returned to Bell Labs Research in early 2010 and has since then been working on and leading research efforts into energy efficient, low power and sustainable communication networks.

He earned an MS in Mechanical Engineering and an MS in Electrical Engineering from the Université de Nantes and the Ecole Centrale de Nantes in Nantes, France.  Thierry received a PhD in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology, USA. He is an author on over 35 peer-reviewed conference and journal publications and an inventor on 36 patent applications. He is the recipient of a Bell Labs’s President Award and two Bell Labs Teamwork Awards. In 2010, he was voted “Technologist of the Year” at the Total Telecom World Vendor Awards.
