Researcher | Benthic Communities Research Group & MAREANO Project

I am a marine biologist with a strong background in statistical and modelling approaches, specializing in spatial analyses and mapping of benthic species, communities, and habitats. My research focuses on the classification and mapping of vulnerable marine ecosystems, including cold-water corals, sponges, and sea pens, as well as biotopes, NiN nature types, and nature accounting typologies.

I have extensive experience with machine learning, regression and multivariate models, ordination, and other advanced modelling techniques. A key part of my work involves developing and refining classification frameworks to optimize how we represent and manage marine nature for conservation and policy applications.

My projects span multiple spatial scales—from local fjords and municipalities to regional (Lofoten) and national (Norway–MAREANO) levels—and include international collaborations with research teams in Iceland and India.
