Research experience

My PhD investigation was focused on the remediation of nitrogen toxicity in recirculating aquaculture wastewaters. The study was conducted using pure cultures of nitrifying bacteria namely Nitrosomonas and Nitrobacter. Mass culture of these nitrifiers cultivated in the bioreactors were used as 'soup' to augment nitrification within an aquaculture system. Mathematical models describing the high density culture of the nitrifiers as pure and co-cultures were developed using Matlab. Bioreactor studies were performed to confirm the validity of the models. A successful field trial was completed at the Australian Aquatic Technologies Pty Ltd. Hervey Bay, Queensland to verify the effectiveness of nitrogen reduction using the cultured nitrifiers.
