Howdy! I’m Joey, a nanophotonics engineer working across the full optical device cycle: electromagnetic simulation, nanofabrication in the cleanroom, and optical metrology. I design metasurfaces and diffractive nanostructures using Lumerical FDTD, COMSOL, and MEEP. The most satisfying part is seeing those designs fabricated and tested, and then watching the measured results line up with the simulations.
I previously worked on optical metrology for AR waveguides at Meta Reality Labs. Now I’m a Physicist/Scientist at Applied Materials, working on nanoimprint tool development and process optimization.
On the programming side, I build simulation, design optimization, and automated data analysis tools in Python and MATLAB, and I’m a MathWorks Certified MATLAB Professional.
