On this page, you can find my CV in an informal version. A formal CV is available on short notice in both English and German.

• Born 1984 in Bonn
• Went to school in Meckenheim and Brussels
• Since 1998 self-employed in different fields of IT (yes, I was 14 when I started, since people keep asking)
• From winter term 2003/2004 student of Computer Science at Bonn University, minor subject biology
• 2007: Research scholarship at Cornell University in the Creative Machines Lab (at the time Computational Synthesis Lab) - topics: Machine Learning, Swarm Behavior, Robotics
• 2009: Finished studies (Thesis about Machine Learning, Swarm Behavior, Distributed Systems, Neural Networks)

Current status: I work as Director, Global BabyCare Process & Engineering DataScience at Procter & Gamble, where I've been since 2017. There, I've built a global network of around 150 data specialists and lead both strategic and hands-on topics in DataScience and Machine Learning. Previously, I was at IVU Traffic Technologies AG, responsible for establishing DevOps techniques across multiple development teams and departments, so I have solid experience in driving change processes.

On the side, I consult for companies on DataScience strategy in manufacturing environments – drawing directly from my own day job. In contrast to many other computer scientists, I really enjoy public speaking, which has become my secondary occupation. My client list now ranges from DAX corporations to banks, consultancies, universities, and the German Parliament.

Usually, I code in Python.

The publications on this web site are a completely personal matter and in no way related to my employers.

Aside from computer science, I am equally interested in how modern means of communication change society. I am also fascinated by the transition from a paper-based society to a mix of paper and digital paradigms – and particularly by what can go dangerously wrong during this transition.

As a hobby, I sometimes enjoy analyzing publicly available data, for example an analysis of the news portal SpiegelOnline. This yields interesting, surprising, funny, and sometimes unsettling insights. I was invited to speak about this at the 33rd Chaos Communication Congress.

The next project of this kind dealt with publicly available data from Deutsche Bahn – again a data topic with societal relevance. Again, it premiered at the CCC (this time the 36th).

All three talks have each reached a million viewers, totaling more than 12 million views.

All of this suggests I should have added a social science degree. I'm fine without one, though.

I also like to write and have a strong passion for topics like Data Science and Machine Learning. This combination resulted in my "A Brief Introduction to Neural Networks", which I extend every now and then, and which has been downloaded well over 100,000 times.

As a currently paused activity, I'd like to mention keeping ants – perhaps not unusual for someone interested in collective behavior. As a hands-on counterbalance to computer work, it's remarkably relaxing to build an ant habitat. I also enjoy photography, which pairs well with the ant keeping.

Overall, I like being outdoors and always enjoy joining biologist friends on field trips, fascinated by whatever's crawling and flying around. I often try to photograph their findings (for example hornets or woodpeckers feeding their young), which the biologists appreciate in turn.
