Reviews 
If you are planning to invite me to review a paper the following is of your interest: I am overcommitted with reviews. So, I tend to decline reviews unless I am in the editorial board of the journal, the program committee of the conference, or it is an invitation from a journal in which I regularly publish. In particular, I decline by default all papers on hesitant fuzzy sets (I am very sorry but I have no time to read them all). Naturally, if a paper seems very interesting to me I may override these rules.

A book: 
V. Torra (2017) Data Privacy: Foundations, New Developments and the Big Data Challenge, Springer.
Introductory text to the field of data privacy, based on my lectures and own research. Data privacy from a technological perspective; problems and solutions of the three main communities working on data privacy: statistical disclosure control, privacypreserving data mining, and privacyenhancing technologies. The content of the book and a definition of data science are reviewed in Chapter 1 Data Science: an introduction.

"Data science is the science of data. Its goal is to explain processes and objects through the available data. The explanation is expected to be objective and accurate enough to make predictions. The ultimate goal of the explanations is to make informed decisions based on the knowledge extracted from the underlying data" (Chapter 1). This book approaches big data, artificial intelligence, machine learning, and business intelligence through the lens of Data Science. The book is structured into three parts: (i) the core concepts of data science, (ii) application domains, and (iii) specific tools for data science.

Research interests 
My research interests are between computer science and applied mathematics. I am interested in approximate reasoning, data privacy, machine learning (data mining and statistical learning), decision making, data aggregation and information fusion, fuzzy set theory. My specialization is in data privacy and in approximate reasoning. In more details:
