**Oliver Bühler**

Oliver Bühler is a Professor of Mathematics and Atmosphere Ocean Science at the Courant Institute, NYU. After studies in Germany and the US, he received his PhD in Applied Mathematics from Cambridge University in 1996. After a tenured lectureship at the University of St Andrews in Scotland from 1999-2001 he joined the Courant Institute in 2002.

His research focuses on the fundamental fluid mechanics of atmosphere ocean flows, with particular emphasis on wave motions and how they interact nonlinearly with each other and, in particular, with other forms of motion such as coherent vortices. This work typically involves asymptotic analysis, stochastic modeling, and targeted numerical simulation. Professor Bühler’s work in this area has produced fundamentally new ideas such as the discovery of previously unknown non-local interactions between waves and vortices that are well separated spatially. He is also an expert in the nonlinear breaking of waves, which is one of the few processes whereby new vorticity can be generated inside a fluid body. Applications of this work include wave breaking and wave-driven currents on beaches, angular momentum transport due to internal waves in the atmosphere, and modeling of deep ocean internal tide interactions with the sea floor. Recently, he has started investigating fundamental questions of two-dimensional and three-dimensional turbulence, which has produced new exact Helmholtz decomposition methods for observed power spectra and exact predictions for third-order structure functions.

Professor Bühler is on the faculty of the Geophysical Fluid Dynamics summer school hosted annually by the Woods Hole Oceanographic Society, he has written a research monograph published by Cambridge University press, and he is an Associate Editor of the Journal of Fluid Mechanics. He has received numerous research grants by the UK research councils, the National Science Foundation, and the Office of Naval Research.
