Designing light and light–matter interaction
My research is rooted in Quantum and Optical Physics, laser diagnostics, micro/nano optical devices, and nanophotonics. I aim to create new principles and practical implementations of optical wavefront control using metasurfaces and metalenses.
The long-term goal is to connect academic discovery and engineering implementation: measuring with light, controlling light, and designing light–matter interaction through micro- and nanostructures.
