My main research area is Computational Semantics, a subfield of Computational Linguistics with applications in Natural Language Processing. Computational semantics research aims at analysing the meaning of natural language, designing meaning representations, and developing mechanisms for reasoning over them. I am interested in both theoretical and application-oriented aspects of natural language semantics, and in cognitive aspects of language learning. In my research, I want to help computers understand the meaning of words and utterances, and perform operations that we, humans, perform with language such as logical inference and translation. I want to help them recognize that one cannot run and sleep at the same time; that cats are pets but so can be iguanas (although less typical ones); that a great book is one I would recommend to a friend, and this in different languages. I am Senior Researcher in the Department of Computer and Information Science (CIS) of the School of Engineering and Applied Science at the University of Pennsylvania, and member of the UPenn NLP group. I am currently on leave from the French CNRS where I hold a tenure researcher position. I am also associated with the NLP group at the Department of Informatics in the Athens University of Economics and Business.
