The goal of my research program is to advance the understanding of atmospheric fluid dynamics and improve state-of-the-art numerical models that inform society of the future impacts of climate change. To that end I combine theoretical principles of classical mechanics and modern tools from applied mathematics with observational analysis and numerical modeling. I am particularly interested in the role of waves and turbulence in the atmosphere and how they shape the Earth's climate. More specifically, I am interested in understanding how moisture is transported and how it interacts with large-scale flow patterns to shape regions of precipitation and evaporation and how the largest waves on the planet, which can propagate into the stratosphere, impact surface climate.
