ALEXANDER K. TAGANTSEV received the B.S. degree from St. Petersburg State University, in 1974, and Ph.D. degree from Ioffe Physico-Technical Institute, St. Petersburg, Russia, in 1982 in solid state physics. Before 1993, he worked in Ioffe Physico-Technical Institute, (1991-1993, head of laboratory), and St. Petersburg State Technical University (1991-1993, professor). He joined the ceramics laboratory of EPFL in 1993 where he was leading ( up to 2016) the section for ‘ Modeling and theory of Electroceramics'. He is also currently engaged as a principle research fellow at Ioffe institute (St. Petersburg, Russia). Tagantsev is a theoretician of a broad domain of expertise from ferroelectricity and phonon physics to electrodynamics of superconductors and quantum optics. He is the author of key results on the theory of microwave dielectrics loss, dielectric polarization in crystalline materials, and relaxor ferroelectricity. He is also known in the field of ferroelectric thin films for elucidating works on the polarization switching and degradation in these systems. He authored or co-authored more than 300 scientific articles and two monograph (on domains in ferroics and tunable film bulk acoustic wave resonators). In 2007, Prof. Tagantsev was entitled to the Honors for lifetime achievement in the field of integrated ferroelectrics by the International Symposium on Integrated Ferroelectrics.
