University of Pavia

Ilaria Cristiani received the PhD in Electronics Engineering in 1998 from the University of Pavia.  Since 1994, she spent three years at the Advanced Research Laboratories of the company Pirelli Cables & Systems in Milan, Italy, working on the exploitation of soliton propagation in high bit‐rate transmission systems.

At present she is Associate Professor in Physics at the Department of Electrical, Computer, and Biomedical Engineering of the University of Pavia. Her teaching activities mainly regard Physics and Photonics classes at the Engineering Faculty. 

The principal scientific activity has been aimed at the experimental study of linear and nonlinear optical phenomena for applications in biophotonics and optical communication systems. She has co‐authored more than 80 papers (Scopus – h‐index 26), published in peer reviewed international journals and she contributed to several invited presentations at international conferences. IC is coauthor of four patent applications, one book (Degiorgio, Cristiani ‘Photonics’ Ed. Springer), and she serves as reviewer for the most important international journals in the field of Physics and Photonics.
