Laura Bégon-Lours

Laura Bégon-Lours, Engineer from the ESPCI ParisTech and Doctor in Physics from the UPMC in Paris, is a post-doctoral researcher in the Neuromorphic Systems and Devices group in IBM Research Zurich. During her PhD in the CNRS/Thales laboratory in Paris (France), she demonstrated ferroelectric field-effects of an epitaxial bismuth ferrite thin film on a high-Tc superconducting cuprate. Then in the MESA+ Institute (University of Twente, The Netherlands) she obtained the epitaxial growth of a polar phase of hafnium zirconate on the semiconductor gallium nitride, by pulsed laser deposition. She then joined the Neuromorphic Systems and Devices group in IBM Zurich, with a Marie-Curie fellowship (H2020 FREEMIND). She develops ferroelectric synapses for neuromorphic circuits, and is part of the EU project BeFerroSynaptic and the SNF project Almond.
