Julian Mak's homepage
I am currently a post-doctoral researcher at the Atmospheric, Oceanic and Planetary Physics (AOPP) sub-department within the Department of Physics, University of Oxford. I am generally interested in fluid dynamical questions relevant to geophysical and astrophysical systems.

"There is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened." -- Douglas Adams
