Dr. Eleni Koutsomitopoulou obtained her PhD in computational linguistics at Georgetown University in Washington DC. She works at the interface of cognitive neurosciences, linguistics, and computer science, where her research focuses on the neural bases of language acquisition, learning and memory, as well as the exploration of neuro-cognitive and computational modelling processes of both unimpaired and impaired natural language. Her past affiliations include the Editorial and Indexing Group at Reed Elsevier Lexis Nexis USA and Europe, and the Research and Development Group at Reed Elsevier Lexis Nexis USA. She is the co-inventor of Fact Extractor, a U.S. patented took-kit for shallow and deep parsing and lexical, semantic and syntactic annotation of XML input aiming at meaning discovery, as well as entity and fact extraction in unstructured data. She has worked in the development of pattern-matching grammars for English, French, Spanish and German for information extraction, data mining and indexing applications. Eleni has been affiliated with the Summer Institute of Linguistics at UND as well as the Computational Linguistics Group at Trinity College Dublin. Her postdoctoral research focuses on neurocognitive modeling with applications to the following two distinct areas: modeling the neurocognitive processes of speech retraining for adults with acquired hearing loss and modeling the dynamics of belief update and belief revision for purposes of knowledge representation and reasoning.
Computational cognitive modeling of typical and atypical speech and language processes, as found in clinical populations such as hearing impairment, and other communication disorders.
