Laura Pilozzi received her degree in physics from the University of Rome “Tor Vergata” in 1996. She is now a researcher at the Institute for Complex Systems of the Italian National Research Council (CNR). Her research interest is in theoretical condensed matter physics and photonics. The main themes of her work are related to radiation-matter interaction and polariton states of semiconductors and their heterostructures as microcavities and resonant photonic crystals and quasicrystals. Nonlinear optical effects and polariton scattering in microcavities are among her research subjects within the composed boson formalism for Wannier excitons.
