Research Description

My research interests include symbolic logic and its diverse applications. More
speci cally, I am interested in the following subject areas:

• epistemic/doxastic logic
• deontic logic
• belief revision and fusion
• logic in arti cial intelligence
• logic in privacy and security
• reasoning about uncertainty
• modal logic
• possibilistic logic
• rough set theory
• many-valued logic
