Matthew Baerman is a research fellow in the Surrey Morphology Group at the University of Surrey. His research focuses on the typology, diachrony and formal analysis of inflectional systems, with a particular concentration on phenomena whose interpretation is problematic or controversial. His work has appeared in such journals as Language, Journal of Linguistics, Morphology, Lingua, and Natural Language and Linguistic Theory. He is the editor of OUP's forthcoming Oxford Handbook of Inflection. Matthew Baerman, Dunstan Brown, and Greville G. Corbett are joint authors of The Syntax-Morphology Interface: A Study of Syncretism (CUP 2005). Dunstan Brown holds an Anniversary Chair in the Department of Language and Linguistic Science, University of York. His research interests include autonomous morphology, morphology-syntax interaction and typology. Much of his work focuses on understanding morphological complexity, such as syncretism and computational modelling of morphological systems. His publications include Network Morphology (with Andrew Hippisley; CUP 2012) and Canonical Morphology and Syntax (co-edited with Marina Chumakina and Greville G. Corbett; OUP 2012). Greville G. Corbett is Distinguished Professor of Linguistics at the University of Surrey, where he leads the Surrey Morphology Group. He works on the typology of features, as in Gender (1991), Number (2000), Agreement (2006), and Features (2012), all published by Cambridge University Press. His recent research has been within the canonical approach to typology and he is one of the originators of Network Morphology. He is co-editor, with Dunstan Brown and Marina Chumakina, of Canonical Morphology and Syntax (OUP 2012)
