In the interest of not always only posting positive things on social media. Got rejected from yet another grant today. To my fellow rejectees: You are not alone, your science is cool and worth doing, this is not your fault, we'll get them next time! Grab a cup of your favorite hot drink, take a breather if you need it, and keep up the good work! 🍡

While I love the social aspect of joined lunch at work, having people suddenly start talking about their love for chopped up animals stuffed into their own intestines and how it tasting good somehow justifies that really ruined my good mood and appetite today πŸ˜”

Taking the train and ferry to next weeks conference to avoid flying. Might be a bit slower, but the layovers are a lot nicer. Got to take a two hour walk on the beach between the trains and ferry πŸ˜„

I just noticed that some 3000 people have watched this already and while that might not be much by YouTube standards it is incredible to me. The largest outreach talk I did before this was to about 80 highschool students and that already felt like a huge crowd. 3000 is just mind boggling! Very heartwarming to see this much interest in my research and cosmology!

Bella Ciao 🎢🎡 🎢🎡 🎢

I was lucky to be invited by a colleague of mine, Bertil Dorch, to his office to have a chat about my research. If you are curious what I work on check it out! We talked about real-time cosmology, the expansion of the universe, dark energy and much more. Since it was my first time doing something like this and the conversation was completely unscripted, I am sure we missed some points. Happy to answer any questions you have!

I did not expect to come back from boardgame night to this! Over a hundred people interacting with this, was honestly expecting this post to go unnoticed! Thank you all so much, what an incredible welcome!

Hi everyone!

After a few years break from conventional social media, here to see if I enjoy this more.

I am a PhD student in cosmology. When not at my desk you can probably find me in the local climbing gym, cooking some vegan food, reading, playing boardgames or spending time outside doing more climbing, hiking, bike packing.

Might use this account for talking about science, hobbies or both.

Originally from Germany currently living in Denmark.
