Hanna Koch

Hanna Koch is a Researcher at the Department of Microbiology and Ecosystem Science, Centre for Microbiology and Environmental Systems Science. She holds Magister and PhD qualifications with active research output through 2025.

Her expertise centers on nitrogen cycle microbiology, specializing in nitrite-oxidizing bacteria (particularly Nitrospira and Nitrospinota phyla). She employs genomic, metagenomic, and phylogenetic approaches to investigate microbial diversity in environmental systems, contributing to UN Sustainable Development Goals related to environmental protection. Key research themes include microbial metabolism, evolutionary adaptation, and ecosystem function of nitrogen-cycling bacteria.

Analysis of her 2023-2025 publications reveals a consistent focus on genomic characterization of nitrite oxidizers, with emphasis on phylogenetic diversity, metabolic pathways, and environmental adaptations across marine and terrestrial ecosystems. Her work bridges computational genomics with ecological field studies.

Koch actively disseminates findings through international conferences, including presentations on genome-based functional studies of nitrite-oxidizing bacteria at major microbiology meetings (2011-2012). Her collaborative research network spans multiple institutions as evidenced by co-authorship patterns.
