Julian Mak's homepage

I am currently an assistant professor (cf. lecturer in the UK system) in the Department of Ocean Sciences (OCES) at HKUST (Hong Kong University of Science and Technology); I also have a nominal appointment as a senior NOC fellow at the UK National Oceanography Centre. I am generally interested in fluid dynamical questions relevant to geophysical and astrophysical systems. For stuff that are more group related (such as research news and recruitment), please go to the GROUP WEBPAGE.

Beyond the page groupings, my contact details may be found under ABOUT, and a calendar of my schedule may be found under TRAVEL. If you are a UG student and looking for research opportunities (e.g. looking for final year project supervision), go to TEACHING to have a look.


  • As a way to usefully procrastinate, I occasionally type up notes of miscellaneous topics I have made, which may be found on this GitHub repository. Feel free to use as appropriate.
  • Animation showing vertical component of vorticity from a NEMO custom model (UNAGI, 10km resolution, beta plane), showing effects of different ways of parameterising the mesoscale eddy activity, which has implications on the long term evolution of the model state (cf. climate).

  • Two animations showing the dispersion of (uniform spherical point mass) rubber ducks under an idealised flow, and a "realistic" flow in the winter condition over the Greater Bay area. Driver code from Dan Bartley, HKUST MPhil student).
