Biography

I must have inherited this passionate curiosity, and so I became a nerdy teenager with a love for math, physics and programming. These were not particularly popular hobbies (to put it mildly), and there were no academics in my family. But I was lucky enough to discover the German youth science competition “Jugend forscht”, and participating opened up a whole new world for me: I met wonderful people my age who shared the same passion.  Winning a national second prize at age 17, I was sent to the USA for a one-month stay, helping excavate Anasazi remains in New Mexico. At age 20, I won a first prize, and was lucky enough to meet the brilliant mathematician Dierk Schleicher, who helped me write up my kid stuff in a professional way.

At the same time, a completely different experience changed my view of life. I spent a year taking care of children and young people with multiple disabilities as a substitute for military service. What I was experiencing felt so much more meaningful than all the academic nonsense. For example, spending several hours trying to persuade five-year-old Nadine to drink water, just enough to survive. Or getting little blind Felix to enjoy going for a walk by letting him touch everything – flowers, walls and nettles. I felt grateful and humbled and painfully made aware of my own limitations, flaws and privileges.

These experiences sent me down an exciting but uncomfortable path. Theoretical quantum physics seemed extraordinarily meaningful and deep to me, but my interests and inclinations put me in a tense position between the chairs of math, physics and philosophy. I wanted to discuss with the best minds, but I hated the idea of elitism. I loved the abstraction of mathematics, but I felt the urgent need to understand something concrete about our role as sentient beings in this universe. There was a flood of questions that all started with “why” and not “how”. In a sense, this is the situation I still find myself in today.

I started studying physics in nearby Erlangen, but then moved to Berlin, where Karl-Eberhard Hellwig and Ruedi Seiler taught quantum information theory, and to a city with a thriving subculture of students and artists. We all enjoyed the freedom of the urban wasteland (still resulting from Germany’s reunification), prioritizing creativity over money in a way almost unheard of elsewhere.  In science, I was very happy for the opportunity to work with Jens Eisert, who inspired me with his inexhaustible energy and wealth of ideas.

When I visit Morsbrunn today, my grandfather is sorely missed. But it is heartwarming to see my son and daughter walk the same paths as I walked back then, but now with my father. I hope that I will be able to help them find their own ways, which may be very different from mine. But I can’t help but be optimistic that they will find their answers to questions that I didn’t even dare to ask.
