DESCRIPTION:Prof. Dragan Damjanovic\nFerroelectrics and piezoelectrics are
  the most versatile multifunctional materials with applications ranging fr
 om medical echography and ultrasonic therapy\, via mobile communications\,
  pressure sensing\, scanning systems\, fuel injection\, memories\, energy 
 harvesting\, heat sensing to image stabilization. Engineering these materi
 als for a specific application is a challenging scientific task. Interesti
 ngly\, tailoring of the properties is often accomplished by introducing de
 fects into materials on various length scales\, and describing those effor
 ts will be a core of this talk. Properties can be controlled by defects by
  adjusting the degree of their randomness\, interaction of defects with st
 rain and polarization\, ionic mobility and introducing dislocations\, to n
 ame only a few available mechanisms. These interventions often lead to dis
 covery of unexpected phenomena\, illustrating the serendipitous nature of 
 materials science\, and opening paths for new applications and improved un
 derstanding of properties. Besides functional properties\, environmental a
 nd biocompatibility issues have to be taken into account when engineering 
 materials\, which makes property optimization particularly challenging. As
  an example\, I will briefly touch upon personal experience with societal\
 , scientific\, and engineering challenges and dilemmas raised in replacing
  lead-based piezoelectric materials with biocompatible alternatives.\nBio:
  Dragan Damjanovic received BSc diploma in Physics from the Faculty of Nat
 ural Sciences and Mathematics\, University of Sarajevo\, in 1980\, and PhD
  in Ceramics Science from the Pennsylvania State University (PSU) in 1987.
  From 1988 to 1991 he was a research associate in the Materials Research L
 aboratory at the PSU and  joined the Ceramics Laboratory\, Department of 
 Materials Science and Engineering\, Ecole polytechnique fédérale de Laus
 anne in 1991. At EPFL\, he was "professeur titulaire"\, head of the Group 
 for Ferroelectrics and Functional Oxides at the Institute of Materials and
  taught undergraduate and graduate courses on structure and electrical pro
 perties of ceramic materials. The research activities included fundamental
  and applied investigations of piezoelectric\, ferroelectric and dielectri
 c properties of ceramics\, crystals\, thin films\, polymers and composites
 . He is a Fellow of IEEE and Fellow of the American Ceramic Society and h
 as received several awards for his research and teaching\, including Humbo
 ldt Research Award. He participated in the organization of several scienti
 fic conferences and was associate editor of four journals. Damjanovic pres
 ently serves as the president-elect of the IEEE Ultrasonics\, Ferroelectri
 cs and Frequency Control Society.\n
