Research


I am a member of the Institute for Computer Science and Engineering (ICIC) and the Artificial Intelligence Research and Development Laboratory (LIDIA).

You can visit the institute's website and the Lab's website to learn about our activities.


My research interests include:

  • Knowledge Representation
  • Defeasible Reasoning
  • Computational Argumentation
Mainly, I have been working on the study and formalization of abstract and structured argumentation systems with different kinds of interactions (such as attack and support relations).
