Marco Fenici obtained his PhD in Philosophy and Cognitive Sciences at the University of Siena in 2011 by defending a dissertation about children’s acquisition of the concept of belief. Before that, he graduated in Logic at the University of Florence in 2005 with a dissertation on epistemic logics and the problem of logical omniscience. His research interests concern the acquisition of concepts, in general, and, more specifically, of mental concepts. He investigates them mostly by referring to developmental studies about social cognition and language acquisition. Beside that, he is also interested in the epistemology of propositional attitudes, the philosophy of psychology, the concept of representation in cognitive sciences, and animal cognition. During his studies, he has been visiting student at the Technische Universitaet (Dresden), at the Institute of Cognitive Sciences and Technologies (Rome), and at the Department of Linguistics of the University of Massachusetts (Amherst).
