More about me

My perspective

People, place
& environmental
change.

My background brings together a master's in GIS and remote sensing, a degree in human geography, and experience in marine, coastal and land-based projects.

Through Sigrøn, I'm developing independent projects and exploring new ways to use geospatial data.

GIS & remote sensing

Spatial analysis, satellite image interpretation and mapping to understand environmental patterns and change.

GEOSPATIAL ANALYSIS

Environmental mapping

Experience across marine conservation, coastal environments, forests and landscape change, with clear maps and visual communication.

LAND, COAST & SEA

Exploring drone applications

Building on training in drones in agriculture, LiDAR and photogrammetry to explore detailed terrain, vegetation and environmental mapping.

Selected professional work

SALT Trail 2.0

Technical contribution at SALT

I worked on the technical side of this project, which explores how satellite observations can help monitor the environmental impacts of nature-based tourism.

Questions I'm
working on now.

Independent projects exploring how geographic data can help us understand our local environment.

Ongoing exploration

01 / WATER QUALITYGOKSJØ, NORWAY

Goksjø water quality

I'm exploring water quality and cyanobacteria in Goksjø, and how satellite data, maps and local observations can help identify patterns and follow changes over time.

02 / LIGHT POLLUTIONDARKNESS & NATURE

Darker Skies

I'm investigating how geospatial data can map light pollution, identify darker areas and help us understand natural darkness as an environmental quality.

Academic research

Boreal forests.
A closer look.

My master's research used GIS and remote sensing to explore forest composition, moisture patterns and recovery after fire in Scandinavian boreal forests.

Let's connect

Have a project
or an opportunity?

I'm interested in work that connects geospatial analysis with environmental questions and practical decisions.
