Research Interests

My research interests span both fungal systematics and molecular ecology, but my background and education extends to botany, including systematics, anatomy, and development.  I am particularly interested in ascomycete systematics and evolution, bryophilous and endophytic fungi, and using next generation sequencing techniques to address questions in microbial ecology and biodiversity. My primary research revolves around two projects:

  1. Investigating the diversity of fungi associated with the liverworts and mosses of Norway under the framework of BryoFungi, a project funded by the Norwegian Biodiversity Information Centre. Bryophilous fungi are a taxonomically diverse assemblage of saprophytes, parasites, pathogens and endophytes that are typically an over-looked and under-studied component of the ecosystem, despite their importance in carbon and nutrient cycling, as well as creating micro-disturbances. My research involves mapping of species distributions, surveys for species new to Norway and new to science, DNA-barcoding of reference specimens, and examining the evolutionary history of various groups of bryophilous fungi.
  2. Elucidating the ecological significance and evolutionary history of spruce endophytes through the iGran project, a Young, Talented Researcher Grant funded by the Research Council of Norway. Endophytic fungi can play a significant role in host resistance and stress tolerance. My research uses metagenomics and NGS amplicon sequencing to investigate the role of endophytes in pathogen resistance in spruce. In addition, my group uses RAD-tag sequencing to characterize the evolutionary history of European populations of spruce endophytes, whose hosts have experienced significant, recent bottlenecks due to evolutionarily recent glaciation events.

In addition, I am involved in a variety of projects with other focuses including: the role of the microbiome in animal health, addressing the ecology of the mycorrhizal symbiosis, the microbial biodiversity of terrestrial and marine arctic ecosystems, the systematics and evolution of mycocalicioid fungi, the diversity and distribution of wood decay fungi, and methods in microbial molecular ecology.
