Artemis Alexiadou is Professor of Theoretical and English Linguistics at the University of Stuttgart. She received her Ph.D. in Linguistics in 1994 from the University of Potsdam. Her research interests lie in theoretical and comparative syntax, morphology, and most importantly in the interface between syntax, morphology, the lexicon, and interpretation. Her publications include The Unaccusativity Puzzle (with Elena Anagnostopoulou and Martin Everaert; OUP 2004) and The Syntax of Roots and the Roots of Syntax (with Hagit Borer and Florian Schäfer; OUP 2014), along with multiple journal articles and papers in conference proceedings. Florian Schäfer is a researcher at the collaborative research centre (Sonderforschungsbereich) SFB 732 'Incremental Specification in Context' at the University of Stuttgart. He studied General and Theoretical Linguistics at the University of Potsdam and finished his dissertation on the (anti-)causative alternation in 2007 at the University of Stuttgart. His main research interests are located in the theories of syntax, morphology and lexical semantics and the interaction of these modules of grammar. He is co-editor, along with Artemis Alexiadou and Hagit Borer, of The Syntax of Roots and the Roots of Syntax (OUP 2014). Elena Anagnostopoulou is Professor of Theoretical Linguistics at the University of Crete. She obtained her Ph.D. in Linguistics from the University of Salzburg in 1994. After a post-doc at MIT (1997-1998), she took a position at the University of Crete in 1998, where she is currently Professor of Theoretical Linguistics. Her research interests lie in theoretical and comparative syntax, with special focus on the interfaces between syntax, morphology, and the lexicon, argument alternations, Case, Agreement, clitics and anaphora. She is the author of The Syntax of Ditransitives. Evidence from Clitics (Mouton de Gruyter 2003), has co-edited four volumes in theoretical linguistics and has published in journals, edited volumes and conference proceedings.
