Prof. Ortmann studied physics and received his doctorate with “summa cum laude” from the Friedrich Schiller University Jena in 2009. In the same year, he joined CEA Grenoble as postdoctoral fellow and was awarded a Marie-Curie Fellowship in 2010. In 2011 he moved to the ICN2 Barcelona and in 2013 to TU Dresden. From 2014, he headed an Emmy Noether junior research group and was group leader at the excellence cluster cfaed from 2017. Since 2020, Prof. Ortmann has been at TUM.
