I am 47 years old, married, and have two children aged 16 and 18. I was born in Germany, spent the first ten years in Bielefeld, and then moved with my family to Cologne, where I still live.

I graduated from high school, did my community service in an environmental institute, and then studied computer science with a minor in business administration at the University of Bonn. I focused on computer security, networks, and finite-state models during my major. I wrote my diploma thesis in cooperation with Fraunhofer about a Europe-wide computer security system.

Since then, I have worked in different roles (expert, project lead, executive) in the financial industry. First in information security, later in architecture and quality assurance.

I’m a knowledge worker, so I’ve long been interested in strategies, methods, and tools for efficiently storing, searching, and networking information.

In early 2020, I became seriously ill with Covid-19. I was in a coma for more than four weeks and had to be kept alive in ICU with ECMO. After waking up, I could not stand, walk, or even open a water bottle. It took me months to recover. That was certainly the most drastic experience of my life.

“Tools for Thought” have helped me find my way back to life. I’m writing a lot about them on goedel.io.

I am quite active on Twitter, if you like, feel free to follow me there. If you want to contact me, don’t hesitate to write an E-Mail
