Who I am, what I do and what other people say

I always wanted to understand how things work. That’s why I studied physics and became a scientist. My research is about novel materials for solar cells, and it’s great fun. But I found what I enjoy just as much is when science meets communication. The moment when complexity turns into clarity keeps fascinating me.

Curiosity also drives me when I’m not in the lab or sitting in front of a computer. I love to explore Europe by train. I’m also a big nature lover and spend lots of time in Finland’s national parks. Sharing my passion with others is what gives me the little extra joy.

After more than a decade in academic research, I’ve decided to become a freelancer. I work on my own behalf and for clients from academia, the publishing industry and the media. If you think I could help you with your project, just drop me a line.

Sometimes you have to change perspective, don’t you?



I earned my doctoral degree from the University of Oldenburg, Germany. My thesis on organic solar cells was awarded the university’s Best Dissertation Award.


A six-week Interrail trip through Northern Europe made me a noted railway person. Tweeting, writing and speaking about train travel ever since.


I worked as a teaching assistant and took my research to the stage. I won a science communication award that helped finance my first research stay abroad.

2018 – 2022

Back to the research front, I worked as a postdoc at universities in Linköping, Sweden and Turku, Finland. My work was supported by a Marie Skłodowska-Curie Fellowship.


Having decided to stay in the country of sauna and happy people, I started a new journey as a freelancer. I’m still finding my way, so why don’t you join me for a bit?



I do my own research and help others with their projects. My background is in solid state physics, especially disordered matter and photovoltaics.


I write about the things I’m excited about, whether it’s science, travel or nature. I’ve contributed to blogs, magazines and books. I also run my own newsletter.

Whatever the audience, I like to get the point across. I’m a heavy Twitter user and serve as an expert for the media. I’ve also designed a website or two.

“Sebastian assisted us with his expertise in space-charge limited current measurements and paper writing in our collaboration project. He was very meticulous and consistent. It was a pleasure to work with him.”

Safa Shoaee
Professor, University of Potsdam

“In the collaboration for the travel guide ‘Europa mit dem Zug’, Sebastian contributed a very well thought-out chapter on Finland. We were very impressed by his expertise and his spot-on writing.”
