Nicolas Grandjean received a PhD degree in physics from the University of Nice-Sophia Antipolis in 1994 and thereafter joined the French National Center for Scientific Research (CNRS) as a staff member. In 2004, he was appointed tenure-track assistant professor at the école polytechnique fédérale de Lausanne (EPFL) where he created the Laboratory for advanced semiconductors for photonics and electronics. He was promoted to full professor in 2009. He was the director of the Institute of Condensed Matter Physics from 2012 to 2016. In 2016, he was invited as a visiting professor at the University of California at Santa Barbara. From 2018 to 2022, he was the head of the School of Physics at the EPFL. He was awarded the Sandoz Family Foundation Grant for Academic Promotion, received the «Nakamura Lecturer» Award in 2010, the "Quantum Devices Award» at the 2017 Compound Semiconductor Week, and «2016 best teacher» award from the EPFL Physics School. In 2022, he received the «Polysphère d'Or» best teacher award from the EPFL student association. He authored more than 600 publications in peered-reviewed journals and delivered plenary talks at major international conferences. His research interests are focused on the physics and technology of III-V nitride wide-bandgap semiconductor quantum photonics. Since 2025, Nicolas Grandjean is Associate-Vice President for Education at the EPFL.
