Vassiliki Efstathiou
Research Associate

Vasiliki Efstathiou is a research associate at the Cognitive Systems Research Institute (CSRI) and the Institute for Language and Speech Processing (ILSP/ATHENA R.C.) currently working on the POETICON++ project (FP7 ICT). Prior to this, she worked as a postdoctoral research fellow with the Information Technologies Institute (ITI) of the Centre for Research and Technology Hellas (CERTH) and as a research associate with the Intelligent Systems group of University College London Computer Science department. Vasiliki holds a PhD in Computer Science from University College London, an MSc in Computer Science from the same University and a BSc in Mathematics from the University of Crete. Her research interests lie in the area of knowledge representation and reasoning with special focus on computational argumentation systems, automated theorem proving and reasoning under uncertainty.  Her Ph.D. thesis was entitled “Algorithms for Computational Argumentation in Artificial Intelligence” and investigated automated reasoning techniques for implementing computational argumentation based on classical logic. Currently, she is working on using computational argumentation in cognitive data, and on computational modeling of language acquisition in infants as a first step of a cognitive approach for taxonomy induction.
