My name is Louis-Alexandre Couston and I am an assistant professor of physics at the Université de Lyon and ENS de Lyon since 09/2020.

If you’re looking for me or want to reach out, try

  • my email: louis.couston[AT], or
  • my office: M1 020, ENS de Lyon, 46, allée d’Italie, 69007, Lyon, France.


I do not have PhD or postdoctoral funded positions to offer at the moment. Prospective students or postdocs with an interest in ocean and atmospheric physics, the cryosphere, and/or space exploration (icy moons) are still encouraged to send me an email as funding opportunities can arise anytime!

Research Projects

This is the list of my most recent projects. Go to the relevant tabs for more information.

  • MIMOP: Modelling Ice-shelf Melting and ice-Ocean Processes (active)

  • SLD: Subglacial Lake Dynamics (active)

  • SCENT: upSCale Energy transfers in NaTure (dormant)

Brief CV

I’ve spent 7 years abroad. Don’t hesitate to ask if you’re interested in moving to or collaborating with the UK or US.

Research Interests

These are the kind of keywords that go into the paper I write.

  • Geophysical Fluid Dynamics (turbulence, waves, large-scale flows, stratification, rotation)

  • Hydrodynamics (instability, wave scattering, wave-wave resonance)

  • Thermodynamics (phase changes)

  • Earth and Space Science (ocean and atmospheric dynamics, planetary cores, subglacial lakes, icy moons)

Solution Methods

This list is not exhaustive. I also hope to get some experiments going soon.

  • Applied mathematics (model reduction, asymptotic and perturbation analysis, spectral analysis)

  • Computer simulations (direct numerical simulations, high-performance computing, immersed boundary methods, phase field methods)
