In 1993, I received a PhD degree in Biogeochemistry at University of Aarhus. Thereafter I worked for 4 years at the newly formed Max Planck Institute for Marine Microbiology in Bremen, where I established a research group using in situ technologies for investigating carbon and nitrogen mineralization in the deep-sea. In 1997-2007, I worked as associate Professor at the Marine Biological Laboratory at University of Copenhagen before I in 2007 was recruited as Professor at Scottish Association for Marine Science to establish a research group in marine biogeochemistry. However, after 3 years, I was invited for a professorship at University of Southern Denmark. This enabled me to expand my research group and to work with a great team of colleges at Nordcee. In 2016 I was awarded a 5-year ERC advanced grant for the exploration of hadal trenches and in 2017 I accepted a cross-appointment with Tokyo University for Marine Science and Technology. This further stimulated my close collaboration with leading Japanese researchers and enabled direct access to research infrastructures for deep-sea exploration. From September 2020, I will be directing The Danish Center for Hadal Research (HADAL) established with support from The Danish National Research Foundation.
I am a biogeochemist with strong interests in microbiology. I have particular interest in ecosystem responses towards environmental and climatic changes. I have developed and applied novel sensor approaches and in situ technologies for studying benthic carbon and nutrient turn-over in many challenging environments, with a focus that span from microscale interactions to global element cycling. I have strong research interests in primary production, carbon and nitrogen mineralization, benthic solute dynamics, element cycling, carbon preservation and interactions between fauna, microbes and virus. During my career, I have maintained a strong interest in deep-sea environments and in recent years increasingly focused on life and element cycling in the deepest parts of the global ocean; The hadal trenches.
