Fields of expertise
BiographyAfter a Master and a PhD in Physics at EPFL in the field of Electron Microscopy, I joined the Centre for Electron Microscopy and Microanalysis of the University of Western Australia (UWA) in Perth in 2000. In 2002, I came back to EPFL at the Centre for Electron Microscopy (CIME) of EPFL as scientific researcher with Prof. C. Hébert, and as responsible for various projects in the field of material science (solid oxide fuel cells, photovoltaic and metallurgy). I have supervised 6 PhD students in material sciences, and took part of the teaching duties for bachelor, master and PhD students, as well as in the TEM users training and support. In 2012, I joint part time the Laboratory of Photovoltaïcs and Thin-Film Electronics (PVlab) as deputy director of the laboratory. I work full time there since 2014.
School AssemblyI have been part of the basic science school council and of the school assembly (AE) for nearly 5 and 9 years, respectively. It gave me the opportunity to express my opinion on various project and to defend EPFL collaborator's interests. I appreciated the constructive way that AE communicates with the Direction and tries to find optimal solutions for the whole community. I would like to continue to be active in school participation, therefore I am again candidate for the school assembly. In addition, as part of IMT EPFL Neuchâtel, I believe it is very important that external antenna from EPFL has representative at the school assembly to maintain a good connection with the main campus life.
