Biography of Johannes Frantti

Johannes Frantti graduated from the University of Oulu with a M.Sc. in Electrical Engineering and received his Dr. Tech. with honors in Materials Physics from the University of Oulu. Between 1991 and 1997 he was working at the University of Oulu, between 1997 and 1999 and between 2000 and 2005, he was a researcher at the Tokyo Institute of Technology, and in 1999, he was working at the Naval Research Institute in Finland. In 2005, he received an Academy Research Fellowship and joined the Helsinki University of Technology.

In 2005 he was ranked as first for the Technical Physics Professor, University of Oulu, by Professor Mike Glazer of University of Oxford and 2010 as one of the three candidates chosen for the last round for Professorship in International Energy Science Program of Kyoto University. He has over twenty-five years of experience on materials physics, including both experimental and theoretical studies on several functional materials, such as ferroelectric, magnetic, photocatalytic and gas-sensor oxides. He is a Docent at the University of Oulu and his lecturing experience covers courses and lectures given in various universities and research institutes. He initiated many ongoing research projects on ferroelectrics and new material development at the universities. In graduate school he became interested in neutron diffraction while modelling Raman scattering data collected on ferroelectric perovskites. At that time there were only a handful of structural data available. Eventually, during his stay in Japan he got in touch with Professor Sten Eriksson, with whom he conducted his first neutron diffraction experiments at Studsvik Neutron Research Laboratory. His research experience covers collaboration with large-scale research centers, including the Oak Ridge, Los Alamos, Brookhaven and Argonne National Laboratories, Rutherford and Appleton Laboratory, Paul Scherrer Institut and international universities (e.g., University of Oxford, Simon Fraser University, Chalmers University of Technology and King Abdulaziz University) and research centers. He is participating on the European Spallation Source activities, where he represents FRE.

He is enthusiastic in applying new materials in industrial applications and prefers to have hands-on in sample synthesis, analysis, modelling, code writing and facility design. State-of-the-art experimental scattering and diffraction and sample synthesis techniques, such as neutron and synchrotron x-ray scattering, Raman scattering, electron microscopy and electrical and magnetic characterization methods and thin film deposition are applied in his experiments. At his early career stage, he built and tested a pulsed laser ablation deposition chamber. He is interested in to study materials properties under extreme condition, example being large hydrostatic pressure neutron powder diffraction studies. Raman scattering has been an important technique in his studies, as is demonstrated by the seven-year period spend at the Tokyo Institute of Technology in Japan, where his focus was on Raman and resonant-Raman scattering measurements. For modeling and analyzing the experimental data, he applies various computational methods, including methods and computer codes developed by him and his co-workers for parallel computation platforms. Additionally, he applies density-functional theory -based techniques, Rietveld refinement and various quantum mechanical models. Both supercomputers and PC-computers are utilized for modeling and analysis work. He is currently involved in the development of new insulating room-temperature ferromagnetic materials for all-spin-logic, memory, microwave and rf-devices and the development of software for modeling of disordered materials. Johannes has published about 100 scientific research papers, including peer-reviewed journal articles, book chapters and conference papers and has granted and pending patents. He is a board member of FRE and Reciprocal Engineering – RE Ltd. He is a native Finnish speaker and also speaks Japanese.
