My research spans a wide range of subjects, from theoretical fluid dynamics to numerical analysis. My primary research focus is on nonlinear interactions of waves in geophysical fluid flows, i.e., in the atmosphere and oceans. Wave interactions give rise to large-scale phenomena, such as the quasi-biennial oscillation between easterly and westerly winds that is observed in the tropical stratosphere, and smaller-scale phenomena, such as downslope windstorms and turbulence over mountains. It is important that wave effects are represented accurately weather and climate models. My investigations aim to provide us with the needed understanding of the effects of the waves, as well as the mechanisms for their generation and propagation.

我的研究涉及广泛的学科，从理论流体动力学到数值分析。我的主要研究重点是地球物理流体流动（即大气和海洋）中波的非线性相互作用。波浪相互作用会产生大规模现象，例如在热带平流层中观察到的东风和西风之间的准两年一次的振荡，以及较小规模的现象，例如下坡风暴和山脉上的湍流。准确地表示天气和气候模型中的波浪效应非常重要。我的研究旨在让我们对波的影响及其产生和传播的机制有必要的了解。
