Lebenslauf

Scientific Career

Benoit Merle graduated with distinction from the Ecole Centrale de Lyon in France in 2005. After spending a few years as an engineer with Siemens AG, he joined the University of Erlangen-Nürnberg in order to pursue a PhD on the mechanical behavior of thin films. He obtained his doctorate degree (Dr.-Ing.) with distinction in 2013 (advisor: Prof. M. Göken) and went on to establish the nanomechanics and thin films research group which he currently leads.


Research Focus

Benoit Merle strives to develop new micromechanical methods and apply them to metallic and ceramic materials in order to improve our understanding of size effects on the mechanical properties. His main focus lies on nanoindentation and the mechanical testing of freestanding thin films.


Distinctions

He is the author or co-author of a number of publications in international peer-reviewed journals - as listed below - and has given 3 invited presentations abroad. The quality of his work has been acknowledged by the young academic awards that he has received from the German materials society (DGM) and the Staedtler Foundation. He has also received 2 teaching awards for his lectures at the University of Erlangen-Nürnberg and has joined the board of studies for the nanotechnology curriculum in 2015.
