## Biography

Krzysztof J. Cios, a Polish-American computer scientist, was born in Dębica, Poland. He earned his M.S. degree in electrical engineering and his Ph.D. degree in computer science, both from the AGH University of Science and Technology, Kraków, Poland. Cios also earned his D.Sc. (habilitation) degree from the Polish Academy of Sciences, Warsaw and an M.B.A. degree from the University of Toledo, Ohio.
Dr. Cios worked at the Tadeusz Kościuszko University of Technology, Kraków, and the International Atomic Energy Agency, Vienna, Austria. In the U.S. he worked at the Electrical Engineering and Computer Science Department as well as at the Department of Bioengineering at the University of Toledo (UT), Ohio. He was a Fulbright Scholar at the National Institute of Cardiology, Warsaw, Poland. He also worked as a visiting scientist at NASA Glenn Research Center, Cleveland, Ohio. Cios served as Chair of the Computer Science and Engineering Department at the University of Colorado Denver where he was instrumental in starting its Ph.D. program in Computer Science and Information Systems. He consulted for Lockheed Martin and Raytheon companies.He has also worked as a visiting professor at the Complutense University of Madrid, Spain, and at the Muroran Institute of Technology, Japan. He served as Chair of the Computer Science Department at VCU from 2007 to 2023, where he started a dual Ph.D. degree program in computer science between VCU and the University of Cordoba (UCO), Spain. He also served as Director of Enterprise Informatics, Office of the Vice President for Research and Innovation at VCU.
Prof. Cios has co-authored three books and over 200 journal and conference papers. His main contributions are in the areas of machine learning, computational neuroscience, and data mining. His book on data mining was the first such published (1998) in the U.S., while paper on medical data mining became influential in the field. In the area of neuroinformatics, he defined with his collaborators a new Synaptic Activity Plasticity Rule for networks of spiking neurons. Several of machine learning algorithms developed with his students were implemented in open-source software platforms.
Prof. Cios has been the recipient of the Norbert Wiener Outstanding Paper Award (Kybernetes), the University of Toledo Outstanding Faculty Research Award, the Neurocomputing Best Paper Award and the Fulbright Senior Scholar Award. He is listed by the Kosciuszko Foundation as one of the eminent scientists of Polish origin and ancestry, He is a Foreign Member of the Polish Academy of Arts and Sciences, a Fellow of the American Institute for Medical and Biological Engineering, a Fellow of the Asia-Pacific Association of Artificial Intelligence, and a Life Fellow of the IEEE ("for contributions to data mining and machine learning").
