Personal profile

Research interests

I am acting as a Research Team Leader in Nuclear Reactor Materials team. Our team is involved in mechanical testing of NPP components in hot cell environment, microstructural characterization by using state of the art electron microscopes, as well as different type of failure analyses on structural materials. My own expertise is related to high temperature oxidation of structural materials, like ATF claddings. I'm also familiar with different future type of reactors like GenIV and their material solutions. I'm taking actively part in different international forums/working groups like EERA JPNM (SC member), GIF & IAEA.
