A Jupyter Book about SPy
I created and published a Jupyter Book about SPy, the new companion static language for Python.
I am a CNRS researcher at LEGI (Laboratoire des Ecoulements
Geophysiques et Industriels, UMR 5519).
My main research interests concern fluid dynamics and
turbulence, mainly applied to geophysical flows. In my work, a
combination of lab experiments, numerical calculations,
theoratical derivations and data analysis are used in order to
investigate instabilities and turbulence in stratified and
rotating fluids.
I also work on how to program and calcul for science, in particular
using Python and its ecosystem, and teaching about these subjects.
