I am an Associate Professor of Physics at the Department of Physics and Astronomy of the University of Southampton (United Kingdom), where I lead the Solid-State Quantum Optics group.

I graduated from the University of Padua (Italy), 110/110 cum laude, with a thesis entitled "Optical properties of quantum dots in a magnetic field", carried out at the Ecole Normale Superieure de Paris (France).

I obtained my PhD from the University Paris-Diderot (France), Mention Tres Honorable, with a thesis entitled "Electrically injected semiconductor devices operating in the light-matter strong coupling regime".

I am recipient of the Ing. Aldo Gini Prize of Excellence, the Chair of the Semiconductor Group of the Institute of Physics, co-chair of the Non-linear Optics Technical Group of the Optical Society of America, a member of the American Physical Society, of the Optical Society of America, of the European Optical Society, of the Institute of Physics and a Fellow of the Higher Education Academy.

Research

Research interests

My research activities are focused on the fundamental understanding of quantum optics phenomena with solid-state emitters in nano-fabricated quantum photonic devices. Besides fundamental research, I also works towards the enhancement of the light-matter interaction on a chip for energy harvesting, sensing and quantum information technology applications.

My research work in the nano-photonics area has covered topics including mid-infrared quantum cascade structures, intersubband polaritons, plasmonics, disordered photonics, nano-imaging, nano-fabrication, single-photon and quantum photonic devices.
