Anastassios Bountis is professor at the Department of Mathematics, University of Patras, since 1990. He graduated from Athens College in 1969, and did his undergraduate and graduate studies in the US, receiving his PhD in Theoretical Physics in 1978 from the University of Rochester in New York.

He has taught applied mathematics at CalTech, Austin and Clarkson Universities of the USA as well as at the Amsterdam University in Netherlands while he was among the first Greeks whose research dealt with the theory and applications of chaos and fractals.

In 1996 he founded the Centre for Research and Application of Nonlinear Systems at the University of Patras, in order to promote interdisciplinary research collaborations as well as the Hellenic contribution to this new science. He is the author of 120 papers and 5 books on theory and applications of Nonlinear Systems, Chaotic Dynamics and Fractal Geometry (four in Greek and one in English entitled «Complex Hamiltonian Dynamics Springer, Series in Synergetics, Springer Verlag, 2012).

In 2009, he received an award by the Academy of Athens for his work in Dynamical Systems, while in 2010 he organized an International Conference, in Thessaloniki, on Nonlinear Dynamics and Complexity in honor of his 60th birthday (see

The Hellenic contribution to the new Complexity Science


Professor A. Bountis has focused his activities in areas of the new Complexity Science. This science, which is based on the mathematical theories of Chaos and Fractal Geometry, proposes new approaches and new methodology for addressing problems associated with complex systems of many sciences.

Professor A. Bountis and his research team particularly address issues of Classical Mechanics, Astronomy, Physics, stability bonds in high-energy accelerators and Nonlinear Dynamics applications in Biomedical and Economics problems.

Among the most important contributions of Prof. A. Bountis and his research team during the last 10 years is a series of results related to regular and chaotic dynamics of many degrees of freedom in Hamiltonian systems. These results have allowed Prof. A. Bountis’ team to provide answers to critical questions about Classical Mechanics dimensional atomic lattice and the interpretation of the oscillations in the thermodynamic limit by Statistical Mechanics, the collapse of the known as “FPU repetitions” and the transition from regular to chaotic small and large scale behavior, to determine conditions of stability proton beams in high-energy accelerators by analyzing complexing illustrations, and analysis of stable orbits of small celestial bodies, perpendicular to the circular motion level of N large bodies.

Moreover, A. Bountis has produced interesting results by applying the theory of Nonlinear Dynamics and Chaos in Medicine and Communication Technology issues, in close collaboration with Professor A. Bezerianos team at the Department of Medicine, University of Patras. Since 2009 he is the director of the Inter-University Network entitled "Modelization and Analysis of Biomedical and Physical Systems» (MABIPHYS) with the participation of laboratories and research groups of several Departments of University of Patras (see
