About Julia

I have previously conducted research in the USA, Canada, Australia and the UK, with topics ranging from laboratory analog experiments of the large-scale ocean overturning to much smaller scale coastal process studies.  I am a big believer in the collection and analysis of field data to validate and improve theoretical and numerical models.  When not working, I like to play outside, particularly on ice.

Research Interests

Physical oceanography, coastal ocean dynamics, geophysical fluid dynamics. In particular: exploring mixing and turbulence processes in coastal environments based on field observations; use of laboratory experiments to elucidate fundamental physical processes that cannot be resolved in large-scale numerical models; vegetation dynamics.

Research Supervised

I am currently seeking graduate students to partake in exciting coastal research projects.  Please contact me with any inquiries.  I am particularly keen to hear from students with a strong mathematics, physics or engineering background.
