His research project is examining the use of seaweeds for the removal of nutrients from recirculating aquaculture systems. He is comparing the efficiency of different designs of seaweed scrubber systems for removing nitrogen compounds from waste water. The designs include free floating seaweed systems and seaweed turf scrubbers. He is based at the NIWA aquaculture facility in northern New Zealand, and is using effluent from a commercial abalone farm for his research. He is co-supervised by Rupert Craggs from NIWA who has expertise in designing advanced natural waste water treatment systems and is a Principal Scientist and Manager of NIWA's Aquatic Pollution Mitigation Group.
