Research

From data, to dynamics, to impacts

My research sits at the intersection of physical oceanography, data science, and high-performance computing. It is organized around three connected lines: building the data and methods to observe the ocean across scales, using them to understand multiscale physical processes, and tracing how those processes affect ecosystems and human populations.

1 · Data-driven
Methods to fuse, share, and learn from large environmental datasets

2 · Dynamics
Multiscale physical processes in the ocean and atmosphere

3 · Impacts
How multiscale physics affects ecosystems and people

Data-driven methods

I develop methods and open-source tools to fuse observations and model output across platforms and scales, distribute them as open, analysis-ready datasets, and extract insight from them using high-performance and cloud computing, statistics, machine learning, and scalable visualization.
