Title: Ocean waves: the perfect example of a complex system

Abstract: Scales in ocean waves range from the molecule size (of the order of the nanometre) to the size of the earth (several thousands of kilometres). In this talk, we will explore the complexity of this wide range of waves. We will describe the scientific challenges associated with the study of ocean waves and how a multidisciplinary approach is often the only way to move forward. Ocean waves can be both beneficial to society and damaging to infrastructures when they become highly energetic. We will focus on two particular topics: (i) Extracting the energy of ocean waves: why has it mostly failed so far? and (ii) Building our own wave observation station in a remote area on the west coast of Ireland: how involving the local community has played a vital role in shaping the success of the station

Bio: Professor Frédéric Dias received a PhD in Civil and Environmental Engineering from the University of Wisconsin, Madison, USA, in 1986. He started his career in the US before coming back to France to join CNRS in 1990. In 2000, he moved to Ecole normale supérieure Paris–Saclay (ENSPS) and has been a Professor of Applied Mathematics since. In 2009, he went to University College Dublin (UCD) on leave to work on wave energy converters. In 2021, he moved back to ENSPS while keeping links with UCD. He is leading the joint ENSPS/UCD wave group. He has received four grants from the European Research Council (ERC), two advanced grants and two proof of concept grants. His work deals with extreme wave events, wave breaking and wave measurement. In the latest proof of concept grant, he uses wireless wave sensor technology deployed on a connected buoy to measure and instantaneously transmit raw data of the sea state at a given location, at a low communication cost.
Prof. Frédéric Dias is a member of the Royal Irish Academy, the Academy of Europe and the Norwegian Academy of Science and Letters.
