Dr. Iurii Timrov

Dr. Iurii Timrov is a senior research scientist with extensive experience in the field of computational materials science. In 2013 he obtained his PhD in physics with honours from the Laboratoire des Solides Irradiés at École Polytechnique in Palaiseau (France), under the guidance of Dr. Nathalie Vast. His doctoral research focused on the ab initio study of plasmons and electron-phonon coupling in bismuth, with a particular emphasis on developing a new method for electron energy-loss spectroscopy. His work earned him the distinction of receiving his PhD degree with honours (Très honorable). Following his doctoral studies, Dr. Timrov embarked on a series of postdoctoral positions that further solidified his expertise in the field. During 2013-2016 he conducted postdoctoral research at the Condensed Matter Sector of the Scuola Internazionale Superiore di Studi Avanzati in Trieste (SISSA) in Italy, under the guidance of Prof. Stefano Baroni. During this time, he delved into the development and application of first-principles theory and computational methods for studying molecular systems and various materials' properties. Seeking to expand his research horizons, in 2016 Dr. Timrov joined École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland for his second postdoctoral appointment, and in 2021 he became a staff scientist at EPFL. Working under the supervision of Prof. Nicola Marzari, he made important contributions to the development of extended Hubbard functionals within density-functional theory (DFT) and density-functional perturbation theory (DFPT). His research focused on methodological developments, the design of advanced numerical algorithms, and the investigation of materials' properties at the atomistic scale. Starting from 2023 he is working as a tenure track scientist at the Paul Scherrer Institut (PSI) in Switzerland, Dr. Timrov continues to excel in his field. His research activities center around developing, applying, and disseminating novel methods for accurate and reliable modeling of complex materials, with a specific emphasis on transition-metal and rare-earth compounds.
