Andreas became Research Group Leader in October 2014. He has over 15 years experience in the field of terrestrial carbon cycling focussing on impacts of management and climate change on the soil in forests, agriculture and peatlands, and the functioning of terrestrial ecosystems and ecosystem services provisioning. He developed the MILLENNIA peatland model and uses other carbon models such as Century and DNDC. Recently, he was involved in the UNFCCC in relation to defining peatlands as carbon stores within UN agreements. At the national level, he is involved in many groups related to peatland functioning and management, for example, the Upland Hydrology group and the Upland Management group.
Andreas contributes to teaching in the Department of Environment and Geography in Climate Change modules with a focus on the role of agriculture and land use change and potential carbon cycle-climate feedbacks.
Climate change and terrestrial ecosystem ecology, biogeochemistry, atmosphere-biosphere gas exchange, soil-vegetation-atmosphere modelling (Century, DNDC), agriculture, carbon sequestration and peatland functioning (MILLENNIA peatland model).
Andreas joined SEI York in 2002 as a post doctoral researcher within the Centre for Terrestrial Carbon Dynamics (CTCD). Since 2008 he then joint the National Centre for Earth Observation (NCEO), a follow up of the CTCD.
Andreas also holds PhD in Biology on carbon allocation in the mycorrhizal symbioses from the University of York and works as a part time lecturer at the Centre for Life Long Learning at York University and is a frequent speaker at outreach events on the science of climate change.
Since joining SEI Andreas has developed research in the UK, Europe and Africa with collaborations stretching to the USA. He uses chamber based and Eddie Covariance (EC) tower (analytical) and plant-soil modelling (predictive) methods to estimate carbon dynamics from plot to landscape scales and investigate the effects of climate and management on carbon stocks and associated ecosystem services. He also monitors peatland hydrology and water quality from plot to catchments in relation to climate and management. This work has extended into research on litter decomposition to understand the mechanisms by which peatlands and other soils lock away carbon. He is particularly interested in improving methods and models to assess atmosphere-biosphere exchange of carbon and responses to environmental factors (with a particular focus on soil respiration component fluxes in view to reduce uncertainties in Earth System Modelling of potential carbon-climate feedbacks). To unravel soil fluxes he uses stable isotope labelling techniques (13C) and also radiocarbon (14C) dating.
Defra BD5104: “Restoration of blanket bog vegetation for biodiversity, carbon sequestration and water regulation” http://peatland-es-uk.york.ac.uk/ (Funder Defra UK; £850k; Nov 2011 – March 2017)
This project will acquire experimental data to underpin the development and refinement of possible management techniques, for example, applicable through Environmental Stewardship schemes, to address the dominance of heather (Calluna vulgaris) and facilitate the support of ‘active’ blanket bog vegetation (with peat-forming species, particularly Sphagnum spp.). This requires screening for the most suitable management techniques and then including those as part of a long-term manipulative experiment to provide scientifically sound and meaningful data upon which to base policy advice and subsequently inform management decisions, considering both, environmental and socio-economic implications.
This project has now been extended until 2022 with funding (£840K) from Yorkshire Water, United Utilities, The Moorland Association, BASC and the Yorkshire Wildlife Trust (YPP).

Defra BD5104 contract variation: “to include assessment of management impacts on cranefly emergence and abundance to be related to bird populations” (Defra; £110k; March 2014 – March 2017)
This project is an extension of the BD5104 project investigating how burning and mowing potentially affect insect numbers, particularly craneflies, which are an important food source for several key upland bird species like Golden Plover and Dunlin but also Red Grouse. We collect trap data on cranefly emergence and also transect data on population sizes and relate those to bird numbers by modelling impacts on chick survival and growth. We will use the MILLENNIA peatland model to upscale in space and time as well as specific bird models making use of the collected cranefly and environmental data.

MycoRhizaSoil “Combining wheat genotypes with cultivation methods to facilitate mycorrhizosphere organisms improving soil quality and crop resilience” (BBSRC/NERC; UK Research Councils; £110k Feb 2015 – Jan 2020)
Soil erosion as a result of arable cultivation is a major global constraint on crop yields and efficient use of fertilizer. Symbiotic fungi called mycorrhizas that receive sugars from plant roots in return for providing nutrients and water to the plants can help stabilise soil and contribute to soil organic matter storage. This work will determine the roles mycorrhiza and co-associated soil microorganisms play in maintaining soil structure and organic matter content. In a series of field trials using selected wheat lines the team will determine the extent to which artificial inoculation with mycorrhizal fungi and adoption of no-tillage leads to improvements in soil quality and crop resilience to drought, excess water and native diseases compared to wheat grown conventionally with annual tillage.

Andreas also holds two NERC iCASE studentships on assessing management and climate impacts on soil microbial communities:
