Présentation

Dr Martin Hytch develops quantitative electron microscopy techniques for materials science applications. After carrying out his thesis at the University of Cambridge on the quantitative analysis of high-resolution images (HRTEM) of compound semiconductors in 1991, he moved to France to work at the CECM-CNRS in Paris, where he subsequently joined the CNRS in 1995. He is notably the inventor of the Geometric Phase Analysis (GPA) technique for the determination of strain from high-resolution images and has applied the technique to a wide range of materials problems and nanostructures. He moved to the CEMES-CNRS in Toulouse in 2004 to work on aberration-corrected HRTEM and electron holography. In 2007, he invented the new technique of dark-field electron holography for the measurement of strain and in 2008, he was recipient of the prestigious European Microscopy Award (FEI-EMA), awarded every 4 years at the European Microscopy Congress. Between 2009 and 2014, he headed the nanomaterials group at the CEMES (30 permanent staff). He has authored or coauthored over 130 scientific papers and given 70 invited talks at conferences and workshops.
