Oliver Bond is Lecturer in Linguistics in the Surrey Morphology Group, University of Surrey. His research interests include theoretical morphosyntax, typology, and language documentation and description. His recent work concerns the interface between the morphological component of grammar and the lexicon in Lexical Functional Grammar (Bond 2015) and the grammaticalized functions of Cognate Head-Dependent Constructions in African languages (Bond and Anderson 2014). Greville G. Corbett is Distinguished Professor of Linguistics, University of Surrey, and leads the Surrey Morphology Group. He works on the typology of features, as in Gender (1991), Number (2000), Agreement (2006), and Features (2012), all with Cambridge University Press. Recently he has been developing the canonical approach to typology. Within that approach he has papers in Language on suppletion (2007) and on lexical splits (2015). He is the co-editor of the OUP volumes Canonical Morphology and Syntax (2013; with Dunstan Brown and Marina Chumakina) and Understanding and Measuring Morphological Complexity (2015; with Matthew Baerman and Dunstan Brown). Marina Chumakina is a Research Fellow in the Surrey Morphology Group, University of Surrey. Her work focuses on Nakh-Daghestanian languages and typology. She has done extensive fieldwork on the Archi language resulting in an online Archi Dictionary (with Dunstan Brown, Greville G. Corbett, and Harley Quilliam, 2007) and works on Archi morphosyntax (Chumakina 2013). She is co-editor, with Dunstan Brown and Greville G. Corbett, of Canonical Morphology and Syntax (OUP 2013). Dunstan Brown is an Anniversary Professor at the University of York, and a Visiting Professor in the Surrey Morphology Group, University of Surrey. His research interests include autonomous morphology, morphology-syntax interaction and typology. His recent publications include Network Morphology (with Andrew Hippisley, CUP 2012), and, as co-editor, Canonical Morphology and Syntax (with Marina Chumakina and Greville G. Corbett; OUP 2013) and Understanding and Measuring Morphological Complexity (with Matthew Baerman and Greville G. Corbett; OUP 2015).
