Students and postdocs

I am always keen to hear from potential graduate students who want to partake in exciting coastal research projects. Please contact me with inquiries. I am particularly keen to hear from students with a strong mathematics, physics, physical oceanography, or engineering background. However, please take note that funding postgraduate students in NZ is hard. There are University of Waikato postgraduate scholarships available (more details here) but these are extremely competitive, especially for international students (straight A grades are usually required).

Current supervision activities:


Masaya Yoshikai

Postdoctoral Research Fellow – Masaya is working on our Marsden-funded project looking at sediment transport in vegetated environments.

This photo proves that Masaya is always happy in the field, even when it’s dark and freezing cold (although aren’t mangroves meant to grow in warm places?)…


Vinay Nelli

PhD student – “Bridging the laboratory-field divide to accurately predict the evolution of coastlines

Vinay admiring his fabulous deployment of an Aquadopp.


Shahab Abbaszadeh

PhD student – “Small scale hydrodynamic Controls on Sediment Resuspension and Transport in Vegetated Environments” 

Shahab skipping the gym membership by hauling up a CTD frame


Brooke James

MSc student – “Dynamic controls on the Waihou River salt wedge”  

I’m not sure whose idea it was to let Brooke behind the wheel, still I’m sure she can see where she’s going … erm … probably?



Tiago Dutra da Silva

PhD student – “Impact of fragmentation of seagrass meadows on near bed-hydrodynamics and sediment transport: implications for meadow integrity”

Tiago pretending to be stuck in the mud, but not fooling anyone.
