Profile

Biography

I am a benthic biogeochemist in the OceanBiogeosciences Group (OBG) and I lead the Marine Ecosystem Processes (MEP) Subgroup. My research centres around the biogeochemistry of marine sediments and sediment-water exchange processes with a focus on connections between different element cycles, e.g. the carbon, sulphur, metal and nutrient cycles and the drivers of early diagenetic processes. My main research goals are to better understand the impact of external stressors (natural and anthropogenic) on the benthic environment. My recent work in the UKRI Future Leaders Fellowship "Sandman" focusses on the development of new technologies and approaches to autonomously measure porewater gradients and benthic-pelagic exchange fluxes to improve our understanding of the marine biogeochemical cycling, especially in undersampled and more challenging coastal and marine environments.

Topics of interest include:

Biogeochemical processes in coastal sediments, with a focus on the carbon, nutrient and metal cycles and sediment-water exchanges
Development of new technologies for benthic biogeochemistry and sediment-water fluxes
Fluid-sediment interactions and biogeochemical alterations in deep and shallow hydrothermal sediments and cold seeps
Biogeochemical and ecological impact and monitoring strategies for seepage from sub-seafloor CO₂ and H₂ storage

Projects

Active Projects (2024)

Sandman – A novel technology to understand environmental changes in marine sediments (2024-2028): UKRI Future Leaders Fellowship to develop new technologies and approaches to better understand and quantify benthic biogeochemical processes in marine sediments and to monitor and counteract anthropogenic impacts on the seafloor

ATLANTIS- Atlantic Climate and Environment Strategic Science (2024-2029): Atlantis is NOC's strategic program to enhance the long-term, large-scale ocean observation systems and the ocean value-chain that contributes to key national and international programmes and priorities. The aim of the programme is to provide evidence, tools and knowledge to support the ambition for healthy, biologically diverse and resilient marine environments, a sustainable blue economy and communities safe from natural hazards

FOCUS - Future states of the global coastal ocean: understanding for solutions (2022-2026): The aim of this (Inter-)National Capability project is to develop global understanding of the impacts of climate change and direct human activities on the coastal ocean at the regional to local scale of human interaction, Co-I, WP lead

MOET - Managing the environmental sustainability of the offshore energy transition: a solutions-based approach (2021-2027): MOET will assess the environmental sustainability of offshore wind, blue and green hydrogen, and carbon capture and storage for selected test areas of the UK offshore, and will develop solutions for planning the technology and infrastructure of the offshore energy transition. It will also assess public understanding and acceptance of those technologies

ULTRA- Ultramafic-hosted mineral Resource Assessment (2020-2025): NERC Highlight Topic to study ultramafic-hosted seafloor massive sulphides deposits at the Semenov vent field at the Mid-Atlantic Ridge, Co-I

At-Sea -Autonomous techniques for anthropogenic structure ecological assessment (2021-2024): At-Sea is a part of the NERC-funded INSITE programme and trials the concept of using autonomous submarines for high-tech, low-impact monitoring to pick up any potential environmental impacts at these industrial sites, Co-I
