Research
My research interests are in experimental nanophotonics and nanoelectronics with a particular focus on nanostructured devices scaled down to the ultimate quantum limit where one can control and manipulate individual electrons, excitons, or photons.
The approach utilizes nanostructures made from semiconductor quantum dots, photonic crystals, carbon nanotubes, and graphene. These nanostructures are ideal testbeds for fundamental aspect of light-matter interaction and quantum electrodynamic phenomena of electrons and photons and they address device applications in quantum photonics, optoelectronics, sensing, and information processing.
