Physicist, Emacser, Digitales Spielkind



This site is my personal blog and a focal point for my scattered online identities. I intend to use it as a creative space to put thoughts into writing and share my projects through their various stages. Most content will be related to technology and its social impact (when I am feeling reflective and outspoken) and free and open source software and hacking (when I am just messing about).

Terms I would use to describe myself: Researcher and teacher of experimental (sub-atomic) physics, privacy advocate and free software supporter. Passionate about technology and the playful and self-determined use thereof. Long-term Emacs user.

Co-organizer of events for CriticalTech, a community-learning initiative. CriticalTech’s mission is to create a forum for reflections on technological developments and their interplay with society.

Part of the team of applied.life, a network of coaches, scientists, educators, business consultants, and above all diverse human beings, where I offer workshops and lectures, as well as tailored events.

If you want to get in touch with me, please do so! Easiest is via mail or Mastodon (see also links above). My key’s fingerprint for an encrypted communication channel via GnuPG: DE21 4133 BF26 09D1 4E2C 57BA 0300 335B D019 30A8.

When I visit IRC channels on Libera Chat, Freenode or hackint I usually go by the nickname doctorhoo.
