I received a B.Sc. degree in Computer Science from the Federal University of Rio Grande do Norte (UFRN), Brazil, in 1992, the M.Sc. degree in Computer Science from the Federal University of Pernambuco (UFPE), Brazil, in 1995, and the Ph.D. degree in Electrical Engineering (Artificial Intelligence) from the Imperial College (London), UK, in 1999. I worked as a visiting professor at the Center of Informatics (CIn) of the UFPE for three years and, from 2002, I stayed one year as a researcher at the Institute of Mathematics and Computing of the University of São Paulo at São Carlos (Brazil). In 2004, I joined, as an associate professor, the Department of Informatics and Applied Mathematics of the UFRN. I spent one year as a visiting researcher at the Department of Computational Biology of the Max Planck Institute of Molecular Genetics, Berlin, Germany. Currently, I am a full professor at the Laboratoire d'Informatique Fondamentale d'Orléans (LIFO) at the University of Orléans (France). My main research topic is Machine Learning, with focus on Cluster Analysis, Hybrid Intelligent Systems, and Bioinformatics.
