Thomas J. Bridges has been researching water waves for over 25 years, with contributions in the areas of shallow water hydrodynamics, breaking waves, resonances, instabilities, Hamiltonian structures, solitary waves, and sloshing. He is currently Professor of Mathematics at the University of Surrey, has over 130 published papers, and is leader of the EPSRC-supported project on modelling water wave energy converters. Mark D. Groves has been researching the theory of water waves for over 20 years. He is currently Professor at the University of Saarlandes, Saarbrücken, Germany. His principal contributions have been in the areas of dimension breaking, Hamiltonian structures, spatial dynamics, and the applications of dynamical systems theory and nonlinear functional analysis to the problem of water waves. David P. Nicholls has studied water waves, electromagnetic and acoustic wave propagation, and high-order spectral methods for the past 20 years. He is currently a Professor of Mathematics, Statistics, and Computer Science at the University of Illinois, Chicago. He has over 60 published papers and has received continuous support from the NSF, DOE, and industry.
