01 — About

A short introduction.

I hold a PhD in geoscience from UiT The Arctic University of Norway, with a focus on magmatic and experimental petrology and ore geology.

Along the way I've fallen for the work that surrounds the science: cleaning messy datasets, finding patterns, and building visualizations that make complex data legible to other people. This site collects published research alongside small data projects I've built — partly to learn new tools, partly to see how the methods I use on geochemistry translate to other domains.

Data work, in public.

  1. Streamlit · Geopandas · Matplotlib

    Historical weather, mapped by Land.

    An interactive visualization of German weather data — air temperature, precipitation, sunshine duration — by federal state, using open data from the Deutscher Wetterdienst and shapefiles from the Bundesamt für Kartographie und Geodäsie. Mostly an exercise in pairing GeoPandas with matplotlib inside a Streamlit app.

  2. Spotify API · Web scraping · Pandas

    Billboard top-ten, sixty years of audio features.

    Inspired by a blog post by Robert Ritz, this project scrapes Billboard Hot 100 top-ten singles from Wikipedia, then pulls audio analysis from the Spotify API via spotipy. The question: do the most popular keys and tempos shift across decades?

  3. Altair · Datetime · Streamlit

    Fitness data, rebuilt from Garmin Connect.

    A reconstruction of the fitness data displays from Garmin Connect, built mostly to practice handling datetime data and making interactive plots with Altair.
