About

Since May 2023 I've been working on the Hotspots project, which aims to map Norwegian biodiversity in an attempt to figure out which regions of Norway need to be prioritised for conservation. My work has involved the construction of automated data pipelines which download, process and then integrate a wide variety of data sets into species distribution models, as well as coordinating a team of interdisicplinary researchers and communicating our project results.

Before my time on the hotspots project, I completed my PhD on the joint effects of climate change and invasive species on freshwater ecosystems in Scandinavia. The project involved extensive statistical modelling, but also an eco-sociological exploration of what defines an invasive species, and how people feel invasive species should be managed, particularly in light of climate change. I've also been lucky enough to talk and teach about invasive species and biogeography in Master's courses and public events.

I am a keen scientific communicator, and founded and edited the website Ecology for the Masses. I have written a plethora of ecological articles for different publications, including The Niche, The Biologist, Kaiju Ramen and Unite for Nature. I also produced the podcast Biologists of Middle Earth, which interviewed biologists about fictional research projects based in Tolkein's world.

Between my stints at NTNU I also worked at Ducky AS, calculating and communicating how individuals can make a positive impact on Norway's greenhouse gas emissions. I'm also a member of Scientist Rebellion Norway.

Feel free to get in touch if you have any questions about:

  • Invasive species in Norway or Australia
  • Modelling species distributions using open data
  • Science communication
  • The biodiversity or climate crisis - what it means, what we can do
