Paraskevas Kontis

About

Paraskevas (Paris) Kontis is Associate Professor in Materials Science and Engineering at the Department of Materials Science and Engineering, where he is a member of the Physical Metallurgy group. His current research is focused on providing a fundamental understanding of the structure-property relationship down at the atomic level in materials, with a particular focus on high performance alloys at extreme environments, such as superalloys for aero-engines and land-based gas turbines, titanium alloys and others.

Understanding this relationship at the atomic level, can unlock new alloy design strategies. Primary goal is to use such atomic-scale driven design guidelines for hydrogen-resistant superalloys, aiming to make true the zero emissions dream. For this purpose, he exploits a framework of high-end microscopy and microanalysis methods, such as Atom Probe Tomography (APT).

Paris participates in the Outstanding Academic Fellow program at NTNU (2024-2028) and he is the NTNU Representative for the European "Innovative Advanced Materials Initiative (IAM-I)". He is also the National Contact Point (NCP) for the European Aeronautics Science Network (EASN) since 2024.

Brief CV:

Paraskevas Kontis completed his DPhil work in March 2016 and he was awarded his DPhil degree in Materials Science in May 2017 from the University of Oxford, in the UK. This work was sponsored and performed in close collaboration with Siemens Industrial Turbomachinery, Sweden.

After a short Postdoctoral position at the University of Oxford, he took a Postdoctoral position in July 2016 at the Max-Planck-Institut für Eisenforschung (MPIE). There he was a member of the Microstructure Physics and Alloy Design department of Prof. Dierk Raabe and he was working within the Atom Probe group led by Dr Baptiste Gault. He became Deputy Group Leader of the Atom Probe group from August 2018 until June 2020. Between July 2020 and August 2021, he was the Group Leader of the newly established group at MPIE of “High Performance Alloys for Extreme Environments”. In September 2021, he joined NTNU as Associate Professor in Materials Science and Engineering. For more information, you can also visit his personal website.
