Personal profile

Biography

Jean-Michel Le Floch received his PhD degree from both the University of Limoges, France and the University of Western Australia (UWA), Perth, Australia. He studied high Q dielectric resonators using Bragg reflectors and also whispering gallery modes for metrology applications. In 2007, he was working as an engineer at XLIM research institute. In 2008, he was an Australian Research Council postdoctoral fellow with a ARC International linkage scheme in the Frequency Standards and Metrology (FSM) Group located in the School of Physics at UWA in Perth. Then in 2009, he has been appointed with a 3 year position as an ARC APD in the FSM Group then followed by a two year contract as a research associate where his current work involves designing low phase noise oscillators at extremely high frequencies (EHF), and generate very high stable source in millimetre waves. In 2013 he has been promoted to Research Assistant Professor level.
