معرفی
**Jean Lagacé** is a **Lecturer in Pure Mathematics** at **King's College London**, where he is a member of the **London School in Geometry and Number Theory**. Previously, he was a Research Associate at the University of Bristol (hosted by Asma Hassannezhad) and a Research Fellow at UCL (working with Leonid Parnovski and Alexander Sobolev). He earned his Ph.D. from Université de Montréal in 2018 under Iosif Polterovich. He co-organizes the *Spectral Geometry in the Clouds* online seminar.
His research focuses on **asymptotic analysis** in **spectral geometry**, **elliptic PDEs**, **homogenisation theory**, and the **geometry of numbers**. Key interests include boundary spectral problems (e.g., Steklov eigenvalues), eigenvalue optimisation, periodic/quasi-periodic operators, and lattice point counting in anisotropic domains. He employs tools from operator theory, harmonic analysis, and analytic number theory.
His work spans topics like homogenisation in perforated domains, Steklov eigenvalue flexibility, and Weyl’s law for rough surfaces. He collaborates widely (e.g., with Alexandre Girouard, Mikhail Karpukhin) and contributes to journals such as *GAFA*, *Inventiones Mathematicae*, and *Journal of Spectral Theory*.
No awards are explicitly mentioned. He advises no listed students but actively organizes seminars and collaborates on grants (details unspecified). His affiliation with the London School positions him within a network focused on geometry and number theory.
