About us

Prof. Gertjan Koster


Visiting Professor
Full Professor of Inorganic Materials Science


In 1999 Prof. Dr. Ir. G. (Gertjan) Koster did his PhD on “Artificial layered complex oxides by pulsed laser deposition“. In that same year, he moved to the US to join the Kapitulnik-Geballe-Beasley (KGB) group at the Geballe Laboratory for Advanced Materials, Stanford University. In 2007, he joined the Inorganic Materials Science group, MESA+ institute for nanotechnology, University of Twente, where since December 2019 he has been full professor. In 2014 he was a visiting professor at QMI-UBC in Vancouver and since 2018 he is a visiting professor of advanced materials department K9 at the Joseph Stephan Institute in Slovenia. His research focuses on the structure-property relation of atomically engineered complex (nano)materials, especially thin film ceramic oxides. For the thin film synthesis, he developed the first time-resolved RHEED-system, operating at high pressures up to 100 Pa during pulsed laser deposition. Current research includes the growth and study of artificial materials, the physics of reduced scale (nanoscale) materials, metal-insulator transitions and in situ spectroscopic characterization. Application areas are functional materials for green ICT, neuromorphic computing, integration of oxides with CMOS, model systems for operando studies of oxide interfaces using X-ray spectroscopies or STEM-EELS (e.g., batteries, catalysis). Since May 2018 he has been visiting scientist in Advanced Materials Department K-9 at Jožef Stefan Institute and associate professor at Jožef Stefan International Postgraduate School.
