Research interest

 

My research team work on water and nutrient recycling

We use experimental and numerical modelling techniques to improve the performance of membrane processes to recycle water and nutrients from municipal and industrial waste

We critically examine the performance of polymeric and ceramic membranes in desalination, water recycling, biofuels and meat abattoir applications.

Why did you get into engineering?

I enjoy solving problems

What are your research goals?

Reduce the environmental footprint of water, food and biofuel sectors
