Penousal Machado is an Associate Professor at the Dept. of Informatics of the University of Coimbra in Portugal and scientific director of its Computational Design and Visualization Lab. His research interests include Computational Creativity, Evolutionary Computation, Artificial Intelligence, and Information Visualization. He has chaired related scientific events, including the Intl. Conf. on Computational Creativity (ICCC), the Intl. Conf. on Parallel Problem-Solving from Nature (PPSN), and EvoStar, the European Conf. on Bio-inspired Computing, and he is a member of related steering committees and editorial boards. Among his recognitions is the EvoStar Award for Outstanding Contribution to Evolutionary Computation in Europe. He has given invited keynotes on Evolutionary Computation, Visualization, and Art, his work was featured in the journal Leonardo and Wired magazine, and he has presented in venues such as the National Museum of Contemporary Art in Lisbon and the Museum ofModern Art (MoMA) in New York.Juan Romero is a professor in the Dept. of Computer Science and Information Technologies at the University of A Coruña. His research interests include Artificial Intelligence, Evolutionary Computation, Computational Creativity, Evolutionary Art, and Evolutionary Music. He has chaired related scientific events, including the EvoStar Applications of Evolutionary Computation conference and the Intl. Conf. on Artificial Intelligence in Music, Sound, Art and Design, he cofounded the European Network of Research that led to the latter event. He has guest edited special issues such as Neural Networks in Art, Sound and Design for the Neural Computing journal (Springer), Complex Systems in Aesthetics and Art for the Complexity journal (Hindawi), and Genetic Algorithms on Visual Art and Music for the journal Leonardo (MIT Press). He coedited the book "The Art of Artificial Evolution: A Handbook on Evolutionary Art and Music" with Penousal Machado in 2008. He's a cofounder and Chief Innovation Officer of the company PhotoIlike.com.Gary Greenfield is Professor Emeritus of Mathematics & Computer Science at the University of Richmond. He has chaired related scientific events, including the EvoStar Applications of Evoutionary Computation conference, and he is the Founding Editor of the Journal of Mathematics and the Arts (Taylor & Francis). His computer-generated artworks arise from visualizations of mathematical, physical, or biological processes, focusing the viewer's attention on the complexity and intricacy underlying such processes, most recently he has been exploring the tension that develops when generating minimalist art using complex processes.
