Dr. Patrice Salzenstein obtained his master’s degree and his material science engineering diploma at the Eudil in Lille in 1993, and his Ph.D. in Electronics at the University of Lille in 1996. He worked successively at Thomson CSF LCR (now Thales-TRT), Alcatel Alsthom Recherche and LCIE research laboratories near Paris between 1996 and 2001. He has been working since 2001 at FEMTO-ST-institute in Besancon for CNRS, a government-funded-research organization under the administrative authority of the French Ministry of research. He managed a calibration laboratory on phase noise and short term stability of frequency 2002-2012. In 2010, one of his articles was featured in Electronics Letters for his participation with Czech and Swiss colleagues to the best frequency stability ever measured on a quartz crystal oscillator: 2.5×10-14 at 5MHz. Between 2010 and 2017, his field of interest in research was in optoelectronic resonators and oscillators for microwaves photonics applications. Now he researches the Brillouin-light-scattering and instrumentation with the Micro Nano Science&Systems department of FEMTO-ST.
