Profile Summary

Sébastien Vergnole received an engineering school diploma in Physics from “Centrale Marseille” (France) in 2001, the M.S. and Ph.D. degrees in Physics from the University of Limoges (France) in 2002 and 2005. At that time, he was with the Photonics team of the Xlim laboratory and his research interest was stellar interferometry: particularly, he worked on the potential of using photonics crystal fibers in this field and on the instrumental part of the `OHANA project. Characterization of the chromatic dispersion was one of the main aspects of his studies.
From 2005 to April 2011, he was a research associate with the Industrial Materials Institute of the National Research Council of Canada in Boucherville (Québec, Canada). His main field of research was optical coherence tomography (OCT) and more specially Fourier domain OCT, the 2nd generation OCT system. He has been involved mainly in instrumentation and signal processing challenges.
Since June 2011, he has been project leader with the R&D team of Horiba Scientific (Jobin-Yvon) in Villeneuve d’Ascq (France).
