Prof. Ivan Biaggio received his Ph.D. in physics in 1993 from the Swiss Federal Institute
of Technology (ETH) in Zürich, with a thesis on photorefractive
effects induced by short light pulses. He then held a post doctoral
position in the group of Prof.
R. W. Hellwarth at the University of
Southern California, where he worked on nonlinear optical effects in
atomic
vapours, optical correlators, and polaron mobility in
Bi12SiO20. After a post doctoral stay with the group
of Prof. G. Roosen at the Institut d'Optique Théorique et Appliquée in Orsay, France, working on applications and modelling of the photorefractive effect in the semiconductor crystal Cadmium Telluride (CdTe), he returned to the Nonlinear Optics Laboratory at ETH in 1996 to become the leader of the Photonic Materials Technologies team, where he worked on the nonlinear optical properties and charge transport properties of BaTiO3, KNbO3, Bi12SiO20, and DAST (an organic salt), touching such topics as the charge carrier mobility anisotropy in KNbO3 and BaTiO3, large polaron theory in a multi-mode polar lattice, the hole-mobility in KNbO3, the 2nd order nonlinear optical contributions to degenerate four-wave-mixing in non-centrosymmetric materials, and organic thin film systems for electronics and photonic applications. He received the venia legendi from ETH in 2001 and is an associate Professor at Lehigh since October 2002.
