Teaching

The main two courses I teach are a first year masters cours on Waves in the Ocean and a second year masters course on Geophysical Fluid Dynamics.

Use the links above to follow these two courses on my YouTube channel.

And check out the course notes, written in collaboration with Serena Illig.

For French people writing articles in English here’s my guide:

The Decalogue.

You can also watch me explain it all on video.
