- terrestrial ecology and microbiology
- cold temperate, alpine and arctic regions
- climate change
- soil microbial communities
- soil food web
- PhD thesis: “Exploring the diversity of nivicolous myxomycetes: An analysis of the genetic diversity, species distribution and community composition”.
Supervised by Professor Martin Schnittler.
- Establishing species barcoding and a reference database for dark-spored myxomycetes. Investigating community structure in a parallel barcoding study of the myxoamoebal, bacterial and fungal community from soil along a natural altitudinal gradient.
Fieldwork: German Alps and Rocky Mountain.
Lab work: DNA extraction, Illumina library construction (18S SSU, 16S SSU, ITS) from soil samples, Sanger sequencing, Scanning Electron Microscopying (SEM).
Analysis: Bioinformatic pipelines, multivariate statistics and network analysis.
Software: R (open source), Usearch (open source; Edgar, 2010), MEGA6TM, ImageJ (open source), Gephi (open source), STAMP (open source).
- Master thesis: “Effects of increased warming and shading on soil fungi in Arctic”. Supervised by Professor MSO Anders Priemé.
- Investigating fungal community composition and response to in situ climate change manipulation treatments of increased shading or temperature in a subarctic shrub heath.
Fieldwork: 6 weeks of extensive fieldwork in Kobbefjord, SV Greenland. Measures of in situ CO2-flux’ (Li-COR, IRGA), Normalized Difference Vegetation Index (NDVI, ‘greenness’) and pin-point analysis (vegetation composition and cover).
- Lab work: Illumina library construction (fungal ITS2 amplicons from soil samples), qPCR and enzyme assays (cellulase, laccase). spectrophotometric technics was used to estimate the microbial biomass (MicC, -N and -P) and nutrients (TOC, DON, inorganic-N and -P) in extracts from chloroform fumigated soil samples.
Analysis: multivariate statistics: ordinations and cluster analysis.
Software: R (open source), CANOCO 5TM, STAMP (open source), SAS Enterprise Guide 6.1TM, MEGA6TM.
