Personal Information Publications Research Projects

Dimitrios Savvas was born in Ioannina, Greece in 1961. He was awarded a Diploma in Agriculture from the Agricultural University of Athens (AUA) in 1985 and a Ph.D. degree from the University of Bonn, Germany, in 1992. From 1996 to 2006 he was affiliated with TEI of Epirus (Higher Education Institution) as an associate professor (1996-1999) and professor (1999-2006). In 2006 he became an assistant professor of Vegetable Production in the Agricultural University of Athens. In 2011 he was promoted to the degree of associate professor and since October 2015 he is a full Professor in AUA. Since October 2016 he is the Director of the Laboratory of Vegetable Crops. He specializes in vegetable crops with emphasis on plant nutrition, water management, soilless culture and grafting. He has published over 80 papers in refereed international scientific journals (with IF) and many other papers in congress proceedings (Acta Hort.) and as book chapters. He is a member of the Editorial Board in four international scientific journals with impact factor, particularly Scientia Horticulturae (I.F. 1,538 in 2015), Environmental & Experimental Botany (I.F. 3,712 in 2015), Agricultural Water Management (I.F. 2,603 in 2015) and European Journal of Horticultural Science (I.F. 0,400 in 2015). He has been involved in many EU research projects, either as coordinator or as a member of the research team. In the last 5 years, in addition to several national research projects, Dr. Savvas has been involved in the European research projects LEGUME FUTURES (FP7, coordinator for AUA), SIRRIMED (FP7, member of the research team) and EUROLEGUME (FP7, coordinator for AUA), as well as in two LEONARDO Projects related to plant irrigation and hydroponics (AGRICOM) and Environmental Education (GreeNet). Since 2017 he is coordinating the AUA team in two HORIZON2020 research projects, particularly TOMRES and TRUE
