GreenArc - High Arctic greening in a wetter future
In July 2020, I began this project the Terrestrial Ecology section at the University of Copenhagen, Denmark. The objective is to investigate if polar deserts will become more vegetated under increased precipitation.

OxyMiST - Oxygen Constraints on Microbial Secretomes during Plant Cell Wall Turnover
The large 6 year project will discover new knowledge on fungal degradation of biomass. The focus is on how microorganisms directly or indirectly utilize oxygen in the air with their enzymes. My role in this project revolves around the ecology and sampling of target substrates, particularly poorly decomposing Sphagnum mosses and through co-supervising PhD Student Jonas Thomsen.

With a Marie Curie Individual Fellowship, I investigate the link between cyanobacteria fixed N, mossed and mycorrhizal plant uptake in Boreal and subarctic forest and tundra. Host: Anders Michelsen(University of Copenhagen) Collaborators: Karina Clemmensen, (Swedish Agricultural University), Ellen Dorrepaal, (Umeå Univeristy), Tom Parker (Stirling University). Funding: European Union - Horizon 2020 programme
We are a team of early career researchers, who all spent time at the Climate Impacts Research Centre in Abisko, northern Sweden. After we left to various new positions around Europe, we decided to continue to collaborate and established up a long-term plant removal experiment. In this experiment, we investigate how changes in vegetation composition and their associated mycorrhizal fungi influence plant-soil-microbe interactions and carbon storage.

Moss Functional Groups
This project sprung out of converstations at the 20th International Tundra Experiment meeting held in Parma September 2019. The aim of the project is to develop moss functional ecology within the tundra context.

Mosses as mediators of climate change
During my PhD I studied tree seedling establishment at the alpine subarctic treeline. My main focus wishing this work was to understand if bryophytes modify tree seedling responses to climate change.
