Research

I'm currently interested in the following areas
related to Artificial
Intelligence, and especially to Knowledge
Representation:
 Knowledge
Representation, Reasoning
about Actions and Change
Work in this field is
mostly oriented to the design and
development of action languages (see Functional
Action Language, FAL).
Other topics of interest include the
study of theoretical foundations of causality
or the application to spatiotemporal
reasoning. Some links and incoming
events:
 Logic
Programming
(LP) and Nonmonotonic Reasoning (NMR)
both theoretical
foundantions and practical applications.
I'm interested in the the three wellknown LP
semantics of stable models, wellfounded
semantics and Clark's
completion, and their
application as NMR frameworks for actions reasoning.
In the theoretical field, I'm mostly
concerned with logical interpretations
of general NMR (LP, Default Logic, Modal
nonmonotonic logics, etc) and especially
in the logical characterisation of
stable models: Equilibrium
Logic. Several related links and
events:
This has
widen my interests to the next topic...
 Applied
logics
applications of modal,
temporal, multivalued, intuitionistic
and conditional
logics,
always under the perspective of their
use for NMR.
