Welcome to my webpage!

My research aims at understanding the physics that moduate the air-sea exchange of energy and mass. My current work aims to directly quantify this using a variety of autonomous ocean robotics, ships, and moorings. The results are used to validate climate projections and reduce their uncertainties.

In an effort to be open with my research, and to keep somewhat organised, I keep my code available on GitHub.
