Personal profile

Research interests

Professor Gibb is an environmental microbiologist with expertise in aquatic and marine  systems and the impact of environmental change and industrial pollution on water quality and marine harvest, especially oysters. She is also interested in developing ways to monitor the health of marine systems using multiple values and indicators and led a team that in 2021 produced the first Darwin Harbour Integrated Report Card. She leads the environmental microbiology research group and the Environmental Chemistry and Microbiology Unit (ECMU) at CDU, a high impact research consultancy that works to protect the natural assets of the Northern Territory, specialising in metal, stable isotope, microbiological and molecular analyses in aquatic and terrestrial environments, including analyses of sediment, water and biota. For more than 10 years she and her team have studied Vibrio bacteria ecology and food safety in both artisanal marine harvest and the emerging Tropical Rock Oyster (TRO) industry. They currently have several collaborative, funded projects studying toxigenic vibrio baselines and optimum storage, transport and shelf-life conditions to inform cold supply chains in the north Australian TRO industry. Her scientific output includes over 150 refereed papers, over 4,000 citations and an h-index of 36 (Google Scholar) but the most rewarding aspect of her job is being part of the incredibly dedicated and professional ECMU team, mentoring postgraduate students and collaborations with researchers from other universities, Government, Industry and First Nation Scientists.
