Current Research
Exploring light-matter interaction in low-dimensional systems. Focus areas
include coupling single photon emitters in cavities, exciton-plasmon polaritons, microcavity
exciton polaritons, and Bose-Einstein condensation in exciton-polaritons. Experimental systems
involve microcavities, plasmonic lattices, hyperbolic metamaterials, and both organic and
inorganic semiconductor emitters, such as dyes, quantum dots, 2D materials, and perovskite 2D
nanoplatelets.
