1997: Laurea in Fisica presso l'Università di L'Aquila (110/110 e lode). 2001: Dottorato di ricerca in Fisica presso l'Università di L'Aquila. 2001-2003: Assegnista di ricerca presso il Dipartimento di Fisica dell'Università degli Studi di Roma "Roma Tre". 2003-2005: Ricercatore a tempo determinato dell'Istituto Nazionale Fisica della Materia (INFM) presso l'Unità di L'Aquila. 2005-2008: Ricercatore a tempo determinato di tipo tenure track preso il Laboratorio Regionale CASTI CNR-INFM dell'Aquila. 2009-presente: Ricercatore a tempo indeterminato del CNR. 

Attività didattica: Dal 2001 ad oggi, è stato professore assistente (attraverso contratti compatibili con la sua posizione di ricercatore) per vari corsi presso l'Università di L'Aquila e Roma 3, sia presso il Dipartimento di Fisica (metodi matematici per la fisica) sia presso la Facoltà di Ingegneria (Fisica generale).

Lingue straniere: Ottima conoscenza della lingua inglese parlata e scritta;Elementi di base di francese

Attività di ricerca: Ha svolto attività di ricerca teorica nel campo dell'ottica lineare e non lineare, della propagazione elettromagnetica e della fotonica ed è autore di 90 lavori pubblicati su importanti riviste scientifiche internazionali. Tra i suoi principali risultati in ottica non lineare citiamo: descrizione analitica esatta dei solitoni Kerr TM come soluzioni delle equazioni di Maxwell, l'introduzione di solitoni Kerr contropropaganti in reticoli di riflessione, solitoni spaziali fotorifrattivi con una larghezza dell'ordine del micron basati sulla soppressione del self-bending. Inoltre, nel campo dei solitoni fotorifrattivi ed dell'elettro-ottica ha strettamente collaborato con ricercatori sperimentali con il quale è co-autore di più di dieci lavori contenenti risultati sperimentali. Nell'ambito di tale collaborazione, ha sviluppato l'intera analisi numerica e teorica riguardante le configurazioni sperimentali e l'interpretazione dei risultati. Attualmente sta concentrando i propri sforzi di ricerca nel campo dell'elettromagnetismo (ottica) nonlineare riguardante la propagazione attraverso strutture nonconvenzionali composte da metalli e dielettrici (metamateriali) con l'obiettivo di sviluppare dispositivi non lineari operanti a bassa intensità ottica. Tra i principali risultati relativi allo studio dei metamateriali non lineari, ha predetto la possibilità di osservare un comportamento non lineare si campi con bassa intensità ottica in mezzi con costante dielettrica molto vicino a zero (regime non lineare estremo). Inoltre ha individuato un meccanismo non lineare di superficie (nell'ambito del regime non lineare estremo) che consente l'osservazione di un nuovo tipo di multistabilità elettromagnetica che si verifica in strutture con dimensioni al di sotto della lunghezza d'onda.

1997: He received the Laurea degree in Physics at the University of L'Aquila (110/110 summa cum laude); 2001: He received the Ph.D. in Physics at the University of L'Aquila; 2001-2003: He was junior Researcher at the Physics Department of the University of Rome "Roma Tre"; 2003-2005: He was Researcher of the "Istituto Nazionale Fisica della Materia (INFM)" at the Unit of L'Aquila; 2005-2008: He was Tenure Track researcher at the CNR-INFM CASTI Regional Laboratory of L'Aquila; 2009-present: He is researcher of CNR.

Teaching activity: Since 2001 to present, he has been assistant professor (through contracts compatible with his research position) for various courses at the University of L'Aquila and Roma 3 both at the Physics Department (mathematical methods for physics) and the Faculty of Engineering (General Physics).

Foreign languages: Excellent knowledge of English spoken and written; Basic elements of French.

Research activity:He has performed theoretical research activity in the field of both linear and nonlinear optics, of electromagnetic propagation and of photonics and he is author of 90 papers published on major international scientific journals. Among his main results in nonlinear optics we mention: exact analytical description of Kerr TM solitons as solutions of Maxwell equations, introduction of counterpropagating Kerr solitons supported by reflection gratings, straight micron-sized spatial photorefractive solitons based on self-bending suppression. In addition, in the field of photorefractive solitons and electro-optics he has tightly collaborated with the researchers of an experimental group with whom he co-authored more than ten paper containing experimental results. Within this collaboration, he has developed the overall numerical and theoretical analysis concerning the experimental configurations and results. Presently he is focusing its research effort at investigating nonlinear electromagnetic (optical) propagation through unconventional and novel metal/dielectric structures (metamaterials) with the aim of achieving nonlinear optical steering at low optical intensity. Among the main results concerning nonlinear metamaterials, he has unveiled the possibility of observing a marked nonlinear behavior at small optical intensity in medium with dielectric permittivity very close to zero (extreme nonlinear regime). In addition he has identified a surface nonlinear mechanism (in the frame of the extreme nonlinear regime) allowing the observation of a novel kind of electromagnetic multistability occurring in sub-wavelength sized structures.
