Cláudia Nalon

Position:

I am a lecturer and researcher at the Computer Science Department at the University of Brasília.

Qualifications:

PhD in Computer Science - Department of Computer Science - University of Liverpool
MSc in Computer Science - Institute of Computing - University of Campinas
BSc in Computer Science - Computer Science Department - University of Brasília

Research Interests:

I'm interested in proof methods for combined modal logics, in particular when the resulting language allows for interaction between its components. My PhD was about a resolution-based method for a particular interaction between a linear-time temporal logics and multi-modal S5. This work was part of the EPSRC funded project Resolution-Based Theorem-Proving for Temporal Logics of Knowledge and Belief with Interactions. More recently, I have been working in collaboration with Dr. Clare Dixon, from the University of Liverpool, in a long-term project concerning the development of both theoretical issues and implementantion of tools for normal modal logics. My work in this project is currently funded by CNPq, the Brazilian Research Council (UNIVERSAL 471791/2004-0: Teoria Semântica, Lógica e Aplicações da Computação; CT-INFO 506598/04-7: Simulação Algorítmica, Semântica e Aplicações da Computação).

Prover:

A prototype version of the prover for synchronous systems with no learning can be downloaded by clicking here. You'll need Otter, SWI-Prolog, and Emacs to run the prover. Instructions can be found here. Last updated: 08/06/2004.
