Professor Marija Kosec is a head of Electronic Ceramics Department of Jozef Stefan Institute. She received her B.Sc., Msc. Degree in Chemical Technology and Ph.D Degree in Chemistry from University of Ljubljana,Slovenia in 1970 to 1982.

Her research interest is in synthesis and characterization of electronic ceramics particularly piezoelectrics and ferroelectrics. Her contribution to science is in understanding phenomena of ceramic processing of practically important multicomponent systems. Recent results concern understanding of synthesis of ferroelectric thin films where she explained complicated reactions during solution synthesis and how to control these reactions. Practical results are significantly lower processing temperature. Currently she has been also working on Lead free piezoelectrics, bulk, thick and thin films.She tries to relate research in materials to their application. She authored and co-authored over 150 scientific journal papers and 5 articles in monographs. She gave 46 invited talks on international conferences among them three plenary and 33 invited talks on institutions. She is an editor or co-editor 14 conference proceedings. She has 8 patents and more than 100 technical reports.

She is a member of various Ceramic Societies but also a permanent member of IEEE Ferroelectric Committee, a Senior Member of IEEE and a member of European Liaison Committee (ELC), IMAPS Europe. She is past president of MIDEM (Society for Microelectronics, Devices and Materials of Slovenia) and president of Ceramic Session at the Slovenian Chemical Society. In 2003 she got the award named Ambassador of Science of the Republic of Slovenia in 2004 she became a member of World Academy of Ceramics in 2006 she got the highest national award Zois Price for extraordinary achievements in science. She is a past president of Slovenian Academy of Engineering Sciences.
