Polatidis Efthymios
Academic position: Assistant Professor
Introduction
Efthymios Polatidis is an Assistant Professor at the University of Patras, Department of Mechanical Engineering & Aeronautics, Laboratory of Technology and Strength of Materials. Prior to his appointment, he was tenured beamline scientist, responsible for the POLDI neutron diffractometer of SINQ, at the Paul Scherrer Institute in Switzerland.
Efthymios’ interests lie in understanding the relationship between microstructure, inherited by manufacturing and processing of materials, and their mechanical and functional properties. His experimental work focuses on materials characterization using large scale facilities, in particular diffraction methods, studying the deformation mechanisms and phase transformations and residual strains in engineering materials. His past work involved the development and utilization of novel sample environments for large scale facilities and electron microscopes.
His research has been funded by the Swiss National Science Foundation (SNSF), by the Strategic Focus Area (SFA) Advanced Manufacturing of Switzerland and by internal funding at the Paul Scherrer Institute in Switzerland. He has supervised and co-supervised 4 PhD students and 4 Postdoctoral researchers.
