Speaker Prof. Amin CHABCHOUB Amin received a MSc in Applied Mathematics / Mechanical Engineering from the University of Bremen (Germany), a PhD from Hamburg University of Technology (Germany) and is currently Associate Professor at Kyoto University's Hakubi Center for Advanced Research & Disaster Prevention Research Institute. He previously had an Associate Professor appointment in Environmental Fluid Mechanics at the School of Civil Engineering of the University of Sydney (Australia) and was Assistant Professor of Hydrodynamics at the Department of Mechanical Engineering of Aalto University (Finland). Prior to these faculty roles, he was a Postdoctoral Researcher at Imperial College London (UK), Swinburne University of Technology (Australia), and The University of Tokyo (Japan). His areas of expertise and research interests include extreme waves, solitons, nonlinear dynamics, and physical oceanography.

“The formation of wave localizations in nonlinear dispersive media can be described by weakly nonlinear evolution equations such as the nonlinear Schrödinger equation (NLSE). Within the class of exact NLSE breather solutions on a finite background, the hierarchy of rational solutions, localized in both time and space, are considered to provide appropriate prototypes to model extreme wave dynamics on the water surface, plasma and electromagnetic Kerr media. The talk will focus on the applicability and limitations of hydrodynamic solitons and breathers in unidirectional and directional wave systems. The time-reversal invariance and the effect of dissipation on the evolution of such wave packets will be also elaborated upon. Moreover, the critical role of breathers in wave engineering applications will be highlighted”
