Biography
Ian Pratt-Hartmann read Mathematics and Philosophy at Brasenose College, Oxford, and Philosophy at Princeton University, receiving his PhD. there in 1987.
Dr. Pratt-Hartmann has published extensively in the areas of logic, cognitive science and artificial intelligence. Scientific journals in which his articles appear includeJournal of Symbolic Logic, Bulletin of Symbolic Logic, Journal of Philosophical Logic,Notre Dame Journal of Formal Logic, Journal of Logic, Language and Information,Journal of Logic and Computation and Artificial Intelligence. His current research interests include the complexity of decidable fragments of logic, the relationship between logic and geometry, and the relationship between natural language and logic. He is a member of the editorial board of the Journal of Logic, Language and Information, and one of the editors of the Handbook of Spatial Logic.
Research interests
Dr. Pratt-Hartmann's research interests range widely over the fields of logic, AI and cognitive science. He is chiefly concerned with issues at the interface(s) between logic and complexity theory, logic and geometry, and logic and natural lanaguage.
