Short Bio

I was born in Chiavari, Italy, in 1968. I received the Laurea degree in physics from the University of Pisa in 1992 and the Ph.D. degree in physics from the Scuola Normale Superiore of Pisa in 1997. I then moved to Bell Laboratories, Lucent Technologies, Murray Hill, and in 2000 to the NEST center of Scuola Normale Superiore and CNR-NANO. I am presently Full Professor of Condensed Matter Physics at the Physics Department of Pisa University. My research activities are mainly concerned with devices for the generation and detection of THz radiation and with the investigation of new regimes of light-matter interaction. The demonstration of a THz quantum cascade laser, the first observation of intersubband polaritons, and the development of graphene-based THz detectors are among my best-known achievements.

I have co-authored about 300 publications, have given more than 100 invited talks at international conferences, and hold 16 international patents. I am presently Associate Editor of Applied Physics Letters.

I was the recipient of several awards, among which the Panizza award for opto-electronics of the Italian Physical Society, the Campisano prize for condensed matter physics of the CNR, the Nick Holonyak Jr. award for semiconductor optics of the OSA (of which I am also a Fellow), and the Occhialini medal of IOP and SIF. I was the principal investigator of the advanced grant SouLMan of the European Research Council.

Research Interests

The activity of my group is mainly devoted to the realization of THz photonic devices. After the demonstration of the first ever THz semiconductor heterostructure laser in 2002, our latest developments include the first THz detectors in semiconductor nanowire and graphene field effect transistors. On the fundamental physics side, we investigate the modification and control of light interaction with intersubband transitions in structures with strong photon confinement, observing the formation of intersubband polaritons and studying their electrical and optical manipulation. Recently my group implemented the first experiments of coherent absorption control in a polariton system and in graphene.
