Unlocking Aotearoa-New Zealand's Geothermal Hydrogenotrophs for Renewable Hydrogen Biomanufacturing

About the project

About the Project Can Aotearoa New Zealand's indigenous geothermal microorganisms help power the next generation of sustainable biomanufacturing? This PhD project will investigate whether indigenous hydrogen (H₂)-oxidising bacteria (hydrogenotrophs) from Aotearoa New Zealand's geothermal environments can be developed into next-generation production platforms for renewable hydrogen biomanufacturing. Around the world, hydrogen-powered biotechnology is emerging as a transformative approach for converting renewable hydrogen and carbon dioxide into sustainable products, including protein-rich biomass for food and feed, chemicals, fuels, and advanced biomaterials. Yet most current technologies rely on a small number of model—often proprietary—microorganisms. In contrast, Aotearoa New Zealand's geothermal ecosystems harbour a remarkable diversity of hydrogenotrophic extremophiles adapted to industrially relevant conditions, including elevated temperatures, acidic pH, and naturally hydrogen-rich environments. Despite their promise, their biotechnology potential remains largely unexplored. The successful candidate will work with a unique collection of geothermal microbial isolates and specialised H₂-fed bioreactor systems to optimise microbial growth, hydrogen utilisation, carbon dioxide fixation, and production of valuable bioproducts. Working within a highly collaborative, cross-disciplinary supervisory team, the student will help translate New Zealand's unique geothermal biodiversity into real-world biotechnology with commercial and environmental impact. Applicants must have completed, or be eligible for admission to, a PhD programme at the University of Canterbury. A BE(Hons), BSc(Hons), MSc, or equivalent qualification in bioprocess engineering, microbiology, biotechnology, biochemical engineering, or a related discipline is preferred, together with evidence of significant prior research experience. Experience in microbial cultivation, gas fermentation, bioreactor operation, hydrogen-based bioprocesses, or analytical microbiology would be advantageous but is not essential. All candidates wishing to be considered for this PhD scholarship must submit an application through the official UC scholarship portal by following the link provided (click the View Institution Website link). Applications made by email or direct enquiry alone will not be considered. Applicants should include a CV, academic transcripts, and a brief statement outlining their relevant research experience and interest in the project.
