Mario J. Pérez-Jiménez was born on November 13, 1948, in Bollullos Par del Condado, Huelva, Spain. He received his degree in Mathematics from the Barcelona University (1971) and doctor degree in Mathematics from the Sevilla University (1992). In the past, he was assistant professor at the University of Barcelona (1971-1983), and Guest Professor of the Huazhong University of Science and Technology, Wuhan, China (from 2005). Currently, he is a full professor of Computer Science and Artificial Intelligence at the University of Sevilla, where he is the head of the Research Group on Natural Computing. His main research fields include theory of computation, computational complexity theory, natural computing (DNA computing and membrane computing), bioinformatics, and computational modelling for systems biology and population biology. He has published twelve books in computer science and mathematics, and over 250 scientific papers in international journals (collaborating with many researchers worldwide). He is a member of the editorial board or adviser of several ISI journals such as Artificial Intelligence, BioSystems, Computer Modeling in Engineering and Sciences, Discrete Applied Mathematics, International Journal of Foundations of Computer Science, International Journal of Computers, Communications and Control, International Journal of Computer Mathematics, International Journal of Unconventional Computing, Journal of Logic and Algebraic Programming, Journal of Universal Computer Science, Neurocomputing, Pattern recognition letters, SoftComputing, Theoretical Computer Science, Theory of Computing Systems. He is the main researcher in various European, Chinese, Spanish and Andalusian research grants. He has been involved in evaluation tasks at the regional, national, and international level. He has been and independent expert to the evaluation of NEST (New and Emergent Science and Technology) proposals under the Sixth Framework Programme of the European Community, and since May 2006 he has been an European Science Foundation peer reviewer. He has been the first scientific awarded with "Important Contributions to Membrane Computing" under the auspices of the European Molecular Computing Consortium, Edinburgh, 2008. He is an ordinary member of the Institute of Mathematics of the University of Seville. In 2010, he was nominated as a member of the Council of the Foundation for the Research and Development of the Information Technologies in Andalusia (2010) 。
