Ilaria Cristiani

Role: Associate Professor

Ilaria Cristiani is an associate professor in Physics at the University of Pavia and she obtained her PhD in Electronics Engineering and Computer Science from University of Pavia in 1998 in the frame of joint initiative with Pirelli Cables & Systems. She has been active in research related to nonlinear and integrated photonics for over 20 years, during which she has pioneered work on frequency mixing in lithium niobate integrated devices and soliton dynamics in fibres. From 2007, supported by a grant funded by CNISM – CNR she has started a new research activity on integrated optical tweezers and microfluidics.

Currently, she is mainly active on silicon photonics and integrated photonics for life science.

IC is co-author of more than 80 papers (h-index 27) on international journals, one book (Photonics – Springer) and three patents applications.

During her career she coordinated several national research programs funded by MIUR (Italian Ministry for Research and University), Cariplo Foundations and the National Research Council (CNR). She was coordinator for the University of Pavia in the frame of the EU- FP7 project FABULOUS, she participated in several European cooperation research initiatives (FP6-IOLOS, FP7 NISTAS, COST Actions).

She is currently involved in the project Digital Smart Fluidics Hub project funded by Regione Lombardia. and in the SPEye project (funded by INFN, Istituto Nazionale di Fisica Nucleare) which is a joint initiative for the development of an artificial retina based on silicon detectors in which she coordinates all the optical characterization activities.

From 2014 to 2019 she was appointed as delegate of the Mayor of the City of Pavia taking care of Innovation, Education and Environment Policies.




At University of Pavia she is in charge of two modules for the Laurea degree in Electronics and Bioengineering (Photonics and Physics), she is member of the Board of the PhD in Electronics, Informatics and Industrial Engineering and of the Board for Research & Quality Assessment of the Department of Electronics, Computer Science and Bioengineering of the University of Pavia.
