Hi all! I defended my Ph.D. thesis back in 2019 and I also served as the creator and moderator for the subreddit r/FluidMechanics for a long time. I think with that I have gathered enough experience and courage to answer some of your queries. Some broad topics that I can answer questions on are:

  • computation fluid mechanics
  • scientific programming and HPC
  • nonlinear shallow water equations
  • statistical description of turbulence: spectra, energy budget etc.
  • experimental methods: PIV
  • stratified turbulence
  • academia
  • navigating your career pre- and post-Ph.D.

Ask away!

I’m not in this field. What do you think is the most exciting area of this. Bonus points if you can ELI5.

To me personally, the field is fun because it gives me a perspective on all the processes which drives the weather and climate. I like watching the skies and the seas.

Scientifically the most exciting areas right would be:

  • mixing efficiency: The ocean has a layered structure and it takes 1000s of years for the deep ocean to rise up. Many are trying to understand at what limits the turbulence in ocean currents drives the cold saline deep ocean to starts mixing with warmer fresher waters on the top more effectively. An important question in our changing climate.
  • convection: a classic problem where the heated walls drive convective motion. People are still trying to understand different parameters and how it affects the kind of convection we get. Convection is everywhere: ocean currents transporting heat between the latitudes and, atmosphere which determine where the deserts and rainforests are etc.

How do you see climate change impacting brackish waters?

Brackish waters are basins where inland freshwater meet the seas. With rising sea levels I would expect them to move further upstream or cease to exist - depending on the basin.
