Research Interests

  • Applications of logic to computer science and to philosophy
  • Modal Logics
  • Theory of Truth

I have developed tableau methods for many modal logics, which have been successfully implemented on computers. My work on Kripke-like theories of truth has also been applied to provide semantics for certain programming languages. Some of this work has also found application in non-monotonic reasoning. Recently I have been interested in first- and higher-order modal logics. Applications here range from an explication of Goedel's ontological argument, to semantics for databases of a rather complex sort. My current research involves adding or removing various features from quantified modal logics, to see what the formal consequences are.
