Prof. Camille-Sophie Brès

Short bio

Camille-Sophie Brès is an associate professor at EPFL in the institute of Electrical Engineering. She received her bachelor degree with honors in electrical engineering from McGill University, Canada, in 2002. She obtained her PhD in electrical engineering from Princeton University in 2006. After a post-doctoral position at the University of California San Diego, she joined EPFL in 2011 as a tenure track professor and director of the Photonic Systems Laboratory. She and her team specialize on the design, simulation and demonstration of optical waveguides and devices for enhancing and controlling nonlinear processes aimed at light generation, signal processing, or sensing. The group’s work exploits dispersion engineering offered by integrated photonics, material properties of various optical platforms, and architectural features of systems to enable improved functionalities of nonlinear devices. Since 2023 she is the director of the Doctoral Program in Photonics at EPFL.

She was awarded the early career Women in Photonics Award from the European Optical Society in 2016, as well as ERC starting (2012), Consolidator (2017) and Proof of Concept (2019) grants. She has regularly served on the technical program committees for various international conferences (CLEO US, CLEO Eu, OFC, ECOC, Advanced Photonic Congress), was CLEO S&I Program Chair in 2022 and General Chair in 2024, and is an OPTICA fellow.
