David Embick is a major contributor to the theory of Distributed Morphology, which is famous for its claim that the lexicon does not exist, or at least not as a single component of grammar. Embick’s other research areas involve conceptualizing the interface between the Brain and Language. How can language information be encoded in Neural Networks? Presently he is an Associate Professor in the Department of Linguistics at the University of Pennsylvania. His recent book is titled Localism versus Globalism in Morphology and Phonology. It argues for a cyclic view of syntax and morphology and that Localism should be preferred over Globalism (i.e Phase Based over Optimality Theory).
