Laura Bégon-Lours

Polyvalent, autonomous and dynamic, I enjoy confronting conceptual and technological challenges. During my PhD project, I manipulated ferroelectric and superconducting properties at the nanoscale using near-field microscopy techniques. At MESA+ Institute, I tailored oxide heterostructures at the atomic scale to develop novel polar metals. Currently Marie Curie fellow at IBM, I develop ferroelectric memristors for Neuromorphic computing, in the Neuromorphic Systems and Devices group.
