Biographical sketch: Michael N. Vrahatis (Greek: Μιχαήλ Ν. Βραχάτης) was born in Kalamata, Greece, on April 27, 1955. He received his Ph.D. in Mathematics in 1982 from the University of Patras, Greece. He subsequently performed his military service in the Hellenic Navy from January 1983 to March 1985. His work includes computational mathematics, topological degree and fixed point theory, systems of nonlinear algebraic and transcendental equations, nonlinear dynamics and complexity, numerical and intelligent optimization, data mining and unsupervised clustering, intelligent cryptography, intelligent music, bio–inspired computing, biomedical informatics as well as computational and swarm intelligence. He is a professor in the Department of Mathematics at the University of Patras since 2000. He is founder of the Computational Intelligence Laboratory of the same department which he has been directing since its beginning in 2004. He has been teaching at the undergraduate level for 33 years. Also, he has been teaching distance learning classes at the Hellenic Open University for 18 years. In addition, he has a teaching experience of 24 years at the post graduate level. Several of his doctoral and/or postdoctoral students serve as full professors, associate professors, assistant professors or lecturers in Greece, England and Japan (see students and collaborators).

He was a visiting research fellow at the Department of Mathematics, Cornell University, Ithaca, NY, USA (1987–1988) and a visiting professor to the INFN (Istituto Nazionale di Fisica Nucleare), Bologna, Italy (1992, 1994, and 1998); the Department of Computer Science, Katholieke Universiteit Leuven, Belgium (1999); the Department of Mechanical Engineering, Center for Ocean Engineering, Design Laboratory, MIT, Cambridge, MA, USA (2000); and the Collaborative Research Center “Computational Intelligence” (SFB 531) at the Department of Computer Science, University of Dortmund, Germany (2001). He was a visiting researcher at CERN (European Organization of Nuclear Research), Geneva, Switzerland (1992) and at INRIA (Institut National de Recherche en Informatique et en Automatique), Sophia–Antipolis, France (1998, 2003, 2004 and 2006).

He has served as an experienced reviewer and evaluator of several proposals for research funding organizations and centers of excellence, including ERC (EU), FWF (Austria), IAP (Belgium), MITACS (Canada), NSF (USA), among others. He has participated in the organization of over 280 conferences serving at several positions, and participated in over 230 conferences, congresses and advanced schools as active participant, speaker or keynote speaker. He has served as a reviewer for over 70 international scientific journals and seven books. His editorial activities include work for nineteen international scientific journals (see scientific activities).

The corpus of his work consists of over 400 publications: a) 16 books (including one book published in U.S.A.), b) 143 papers in international refereed journals, c) 20 papers in invited and refereed book chapters, d) 67 papers in refereed book chapters and edited volumes, e) 169 papers in refereed conference proceedings and f) 72 other scholarly publications (including international technical reports (one of CERN, three of INRIA, three of University of Dortmund), invited book–reviews, seminar proceedings, two non–refereed journal papers and one non–refereed full–paper conference article, among others). According to 2017 Journal Citation Reports—Clarivate Analytics, 2018 the number of his publications with journal impact factor greater than 0.5 is 127, while 115 publications have a journal impact factor greater than 1 with the highest being 8.124. The accumulated impact factor of the published journal papers is 280.345 and the average impact factor is 2.207. According to Google Scholar his work has been cited over 14,000 times. Also, 34 of his publications have received more than 100 citations each (i100–index=34). His highest–cited paper has been cited more than 1,700 times, while his h–index is 52, his g–index is 112 and his i10–index is 181 (see publications and citations).
