Logic Research Group

The Logic Research Group is a group of researchers from the Department of Philosophy at the University of Maryland working in logic and related areas. We have special interests in logic and artificial intelligence, modal logics of all kinds (including logics of action, epistemic logics, and deontic logics), conditionals, vagueness, decision theory, game theory, social choice theory, and relations among logic, semantics, and the philosophy of language.
