I am Professor at the Computing Science department, where I lead the "NAUSICA: PrivAcy-AWare traNSparent deCIsions group".

I am working on AI, data privacy and approximate reasoning (fuzzy sets and systems).

I have written several books including:

  • V. Torra, Y. Narukawa, Modeling Decisions, Springer, 2007.
  • V. Torra, Data privacy: Foundations, New Developments and the Big Data Challenge, Springer, 2017.
