Scientists at the MPIE
Dr. Pyuck - Pa Choi (35), born in South Korea, has been working in the department of “Microstructure Physics and Alloy Design” for two years. He is the group leader of the group “3D Atom Probe Tomography”. This hightech equipment, purchased at the MPIE in 2009, analyses steel down to an atomic scale. This special unit of equipment is one of only a handful within europe. Choi’s fields of interest range from the analysis of nanostructured materials to high-strength steel and compound semiconductors. Choi did his PhD on grain boundary segregation in nanocrystalline Al-Cu and Co-P alloys at the University of Göttingen. In 2011 he received the Golden Poster Award for his poster about “Nanoscale Characterization of TI-AlN/CrN Multilayer Hardcoatings” at the 5th International Union of Microbeam Analysis Societies Meeting in Seoul, Korea.
Natalie Tillack (22) has been working as a research fellow at the MPIE since 2009. She was working on her bachelor‘s thesis about “combined ab initio and kinetic Monte-Carlo studies on nano-precipitates in steels” in the department of “Computational Materials Design”. At the moment Tillack is working on her master‘s degree in physics at the Ruhr-University of Bochum and at the University of Oxford. She is investigating oxide-dispersion strengthened steels with ab intio methods. Therefore she is still working at the institute and travelling between Oxford and Düsseldorf on a regular basis. The Friedrich-Naumann-Foundation supports Tillack‘s studies and her stay abroad with a scholarship.
