Raphaël is an Associate Professor at Chalmers University of Technology, where he leads an interdisciplinary research group in integrated photonics, nanomechanics, and quantum technology. His group develops photonic and superconducting platforms that bring together microwaves, mechanical motion, and light, with the aim of realizing low-energy classical and quantum connectivity.

He earned his PhD at Ghent University–imec, contributing to integrated silicon photonics and nonlinear optics. As a Marie Skłodowska-Curie postdoctoral fellow at Stanford University, he worked on lithium niobate photonics and microwave-to-optical photon conversion. His work has led to patented innovations and spin-out efforts in quantum transduction and integrated photonics. The group is supported by the Wallenberg Centre for Quantum Technology, by the Swedish Foundation for Strategic Research through a Future Research Leader grant, and by the European Research Council through a Starting Grant.

His research targets efficient, scalable, high-fidelity operations with photons and phonons in emerging information processing schemes – and studies the physical limits that bound them.
