Nicolas Lebbe

Nicolas Lebbe is a CNRS researcher at the Laplace laboratory in Toulouse, France, specializing in applied mathematics and computational physics for photonic and electromagnetic systems.

• Current CNRS Researcher (2023–)
• Postdoctoral Researcher at Langevin Institute (2022)
• Postdoctoral Researcher at INRIA Sophia-Antipolis (2020–2022)
• PhD in Applied Mathematics from CEA & LJK (2016–2019)

His research focuses on shape and topology optimization, homogenization, and scientific computing applied to nanophotonics and metasurfaces. He developed methods to optimize photonic components using the level-set approach and General Sheet Transmission Conditions (GSTC) for metasurface modeling. His work bridges mathematical rigor with practical electromagnetic and photonic device design.

Nicolas has published extensively on Maxwell equations, plasmonics, and finite element simulations, with key contributions to robust optimization and interface homogenization. His recent publications (2023–2025) emphasize homogenization techniques for curved and quasi-periodic metasurfaces, while earlier works (2017–2019) span robust optimization theory and mid-IR photonics.

He collaborates with institutions like the Langevin Institute, INRIA, and École polytechnique, and has presented at international workshops including OWTNM and GDR MecaWave. His PhD thesis, Contribution in topological optimization and application to nanophotonics (2019), laid foundational work for nanophotonic device optimization.
