Julien Oster

Julien Oster received a Master’s degree in electrical engineering in 2006, a Master’s degree in fundamental and applied mathematics in 2007, both from the Ecole Supérieure d’Electricité (Supélec), France, and a Ph.D. degree from the Université Henri Poincaré, Nancy, France, in 2009. From 2006 to 2009, he was with the Interventional and Diagnostic Adaptive Imaging Laboratory (IADI), Inserm U947, Nancy Université, Nancy, France, and worked in collaboration with Schiller Médical, Wissembourg, France. During this period, he was engaged in research on the real-time processing of electrophysiological signals acquired during Magnetic Resonance Imaging (MRI) acquisitions. In 2010, he worked at the Centre Suisse d’Electronique et de Microtechnique (CSEM), Neuchâtel, Switzerland, an independent, private, non-profit Swiss company for applied research, where he was involved in the development of biomedical signal processing algorithms for wearable technology. He was awarded a Newton International Fellowship by the Royal Academy of Engineering in 2010.

Since 2011 he has been pursuing his research at the Institute of Biomedical Engineering (IBME), Department of Engineering Science, University of Oxford, United-Kingdom. In 2012, Julien was awarded the J.A. Lodge Award from the Institute of Engineering and Technology (IET) in recognition of a promising early-career in Biomedical Engineering. His research activities include the development of techniques for the suppression of the MagnetoHydroDynamic effect on Electrocardiogram in MRI, arrhythmia detection and classification, and mHealth applications.
