Hei 👋

I’m Sebastian Wilken, a scientist, writer and railway geek based in Turku, Finland.

I hold a PhD in physics and have over a decade of experience in academic research. Today I work as a freelance scientist, writer, developer and consultant. I’m also known as a train travel activist. In my spare time, I love to spend time in nature: cycling, hiking, skiing or just looking at things.

On this website you find more about me and my recent projects. Follow me also on Bluesky, Mastodon and Instagram.
