PhD / dr. sc. École Polytechnique Fédérale de Lausanne EPFL (Switzerland) Dipl.-Ing. Karlsruhe Institute of Technology (Germany) My research focuses on predictive atomistic simulation approaches to enable rational materials design. With his expertise on defects (e.g. dislocations, interfaces) in materials, he investigates defect-dominated properties (i.e.; strength, reliability, stability) in advanced engineering materials: ranging from metallic nanomaterials (i.e. nanocrystalline metals, nanoparticle, nanolaminates, nanowires), to refractory metals/high entropy alloys.

Available PhD topics
Scholarships are available Mechanics of nanostructured materials PhD project: The strength and reliability of engineering materials are related to the internal microstructure, which includes materials imperfections (eg, interfaces, impurities, dislocations) with their respective size and distances to each other. Nanostructured materials have extraordinary and unexpected properties compared to traditional engineering alloys due to a nanoscale […]blogs.unimelb.edu.au/materials-mechanics-modelling/2021/09/01/mechanics-of-nanostructured-materials

On the structure of (111) twist grain boundaries in diamond: atomistic simulations with Tersoff-type interatomic potentials
https://doi.org/10.1016/j.actamat.2021.117055 Abstract: In nanocrystalline diamond thin films, the high grain boundary density and the associated grain boundary properties may dominate the overall material behavior. In the present work, we systematically investigate (111) twist grain boundaries in diamond carbon by using atomistic simulations with Tersoff-type potential. Our work reveals the relation between atomic scale grain boundary […] -
Molecular Dynamics Simulations of Nanopolycrystals
http://link.springer.com/10.1007/978-981-10-6855-3_12-1 Abstract: Nanopolycrystals are polycrystalline metals with an average grain size below 100 nm and exhibit extraordinary strength values. In contrast to the coarse-grained polycrystals, the confinement by grain boundaries of the plastic deformation in the grains approaches limits, where the conventional theories break down. In the grain size regime 10–20 nm, molecular dynamics simulations play a […] -

Dislocation interactions at reduced strain rates in atomistic simulations of nanocrystalline Al
https://linkinghub.elsevier.com/retrieve/pii/S1359645417309023 Abstract: Molecular dynamics simulations of transient stress drops have been carried out in different regimes on a nanocrystalline Aluminum sample with average grain size of 12 nm. Besides confirming the interpretation of experimental results obtained during in situ X-ray diffraction, the creep simulations performed at 2 or 3 orders of magnitude lower strain rates […] -

Identification of the intrinsic deformation mechanisms of single-phase body-centred cubic high entropy alloys
A project in the DFG Priority Programme “Compositionally Complex Alloys – High Entropy Alloys (CCA-HEA)” (SPP 2006) Principal Investigators: Ruth Schwaiger, Christian Brandl Body-centred cubic (BCC) refractory high-entropy alloys (HEAs) have been studied as novel metallic systems for high-temperature applications due to their, for example, superior strength, excellent thermal stability, and oxidation resistance even at […]
