The coordinator of Fluid Dynamical Systems is Rui A. P. Perdigão, Physicist at TU Wien. He also serves as Editor in the EGU journal Earth System Dynamics and is the chairman of the Meteoceanics Interdisciplinary Centre for Complex System Science and the associated Doctoral School on Complexity.
Rui Perdigão holds a Doctorate in Physics with the highest honours. He has since then conducted independent and collaborative research on mathematical physics, predictability and uncertainty dynamics, from conceptual and methodological research to applications to fluid dynamical problems in natural sciences and engineering. He has also conducted R&D for large-scale international consortia, including the EU/ESA Copernicus Programme and the North Atlantic Alliance.
As part of his venture across the Earth System sciences, Rui Perdigão has been taking part in the core team of the “Flood Change” consortium, headquartered at TU Wien and funded by the European Research Council. There, he has been serving as the Earth System Dynamics representative, responsible for the development of mathematical physics methods for deciphering coevolutionary hydro-climate dynamics and river flood changes in the light of complex Earth System interactions.
At a more fundamental level, the research conducted by Rui Perdigão focuses on theoretical and methodological developments towards a novel theoretical physics paradigm bringing fundamental physical understanding to nonlinear dynamics and information theory. One of the core efforts in this regard has been the establishment of a nonlinear synergistic dynamic theory of complex coevolutionary systems, unveiling fundamental physical principles and canonic forms bringing complexity to its simplest yet fully generative form.
Rui’s theoretical advances are now being implemented in generalised fluid dynamical systems to address fundamental physics problems ranging across scales from quantum gravitation to coevolutionary earth system dynamics and thermodynamic cosmology. The recently launched frontier lecture series share the most recent progress in these efforts.
With fluid dynamical system applications in mind and particular emphasis on climate dynamics, Rui Perdigão has developed a mathematical physics theory linking interaction information signatures in multiscale geophysical fluid dynamics with underlying mechanisms grounded on nonlinear scale interactions and synergistic emergence in wave mechanics and fluid flow.
In doing so, Rui Perdigão’s advances have brought out novel atmospheric insights on triadic wave resonance among planetary, synoptic and mesoscale waves in fundamental fluid dynamic terms, explaining observed information-theoretical and nonlinear signatures of emergence, and shedding further light on elusive emergent behaviours in multiscale atmospheric flow, e.g. behind far from equilibrium transient dynamics behind “extreme” meteorological phenomena.
More recently, Rui has introduced a non-ergodic coevolutionary theory of information physics, generalising information theory to the realm of far-from-equilibrium statistical mechanics, where there is event codependence and the traditional information theoretical measures do not hold. His novel measures unveil and quantify elusive sources of synergistic and coevolutionary predictability beyond post-critical spatiotemporal memory loss, long after nonlinear multi-information fades away. The collapse of dynamic regimes and nonlinear memory in far-from-equilibrium non-ergodic dynamics is thus no longer an obstacle for system understanding and prediction.
Most of Rui’s advances in Nonlinear Dynamics and Analytics have remained proprietary, securing a leading edge in providing decision support to institutions dealing with critical security challenges protecting the society and the environment. Even so, some of his work is publicly available through publications and courses, and an already contracted comprehensive research monograph will provide a first-hand overview of Rui’s most recent work.
