Pekka Posio is an Associate Professor of Ibero-Romance Languages at the University of Helsinki (Finland). Since his PhD dissertation Pronominal subjects in Peninsular Spanish and European Portuguese: Semantics, pragmatics, and formulaic sequences (2012, University of Helsinki), his research has focused on the interplay of pragmatics, sociolinguistics and morphosyntactic variation in varieties of Spanish and Portuguese. In particular, he has studied the expression and functions of different grammatical persons and personal pronouns in discourse and the emergence of formulaic sequences and pragmatic markers. At present, he is leading the research project Language, gender, and society: Evidence from Mexico and Spain which examines the role of gender identities, roles and expectations in linguistic variation.
Peter Herbeck is currently a postdoctoral researcher at the University of Vienna (Austria) and at the University of Wuppertal (Germany). His PhD dissertation Unifying pro-drop and control - The derivation of Spanish (null) subjects (University of Salzburg, 2015), dealt with null subjects in Spanish finite and nonfinite structures from a minimalist, derivational perspective. Since then, his research has focused on subject expression in Spanish and Catalan speech corpora, investigating how morpho-syntactic, semantic and contextual factors interact to yield subject expression rates. A further research area he is currently working on is the study of morphosyntactic properties of different Valencian Catalan varieties.
