Xian Hadia

I’m a doctoral student in Computational Science and Engineering at Georgia Tech, advised by Raphaël Pestourie. My research focuses on inverse design in nanophotonics.

My work centers on developing computational methods for solving complex inverse problems in electromagnetic design, bridging adjoint-based optimization, surrogate modeling, and scientific computing. I have extensive experience creating custom physics solvers utilizing various numerical methods (FDTD, FDFD, RCWA) as well as using commercial software like COMSOL Multiphysics and Ansys Lumerical. I also have experience leveraging high-performance computing (HPC) clusters for accelerated and accurate simulations. Complementing my theoretical background, I also have hands-on experience within labs for optical metrology and instrumentation for device characterization.

I have successfully applied my research by designing fabrication-ready metasurfaces for applications ranging from focusing and beamforming to arbitrary wavefront manipulation while overseeing the lithographic fabrication process and experimental characterization.
