I’m a research scientist in Earth, Atmospheric, and Planetary Sciences at MIT.

I’m working with the Climate Modeling Alliance (CliMA) to build a new, trainable climate model with quantified uncertainty.

My work aims both to better understand the world, and to improve the fidelity of ocean and climate simulations. I study turbulence and mixing, waves, near-surface processes, and the approximate representation of ocean and sea ice processes in numerical simulations. I also lead the development of CliMA’s ocean component, CliMA’s sea ice component, and the ground-breaking ocean modeling software they are based on, Oceananigans. Oceananigans is written for GPUs in the high-level Julia programming language: highly productive, easy to develop, and 10-50x faster than existing software.
