Her research focuses on understanding the functional roles of microorganisms in biogeochemical cycles, particularly involving hydrogen, sulfur, and carbon metabolism. She investigates Archaea, including Asgard lineages, and their interactions with bacteria and viruses in natural ecosystems. Her work also extends to CRISPR-Cas systems and the recovery of critical resources through microbial processes.

Recent publications highlight her contributions to understanding hydrogenase enzymes in archaea, CRISPR-based functional databases, and the dynamics of microbial and viral communities in response to environmental changes such as wetting and drying cycles. These studies appear in top-tier journals like Cell, Nature Communications, and Microbiome, reflecting the high impact of her research.

Jill Banfield is actively involved in major research projects, including:

• Four Networks for Geologic Hydrogen Storage (2022–2025): Investigating microbial aspects of hydrogen storage in geological formations.
• Bio-recovery of rare earth elements from Australian soils and mine tailings (2020–2024): Funded by the ARC, exploring microbial solutions for sustainable resource extraction.

She collaborates extensively with leading scientists across institutions and contributes to global efforts aligned with UN Sustainable Development Goals, particularly those related to clean energy and responsible resource management. Her work is widely recognized, having been cited in news outlets, blogs, and Wikipedia, and she maintains a robust research output with over 480 publications since 1985.
