I was professor for Computer Science at the Freie Universität Berlin and headed the group on Networked Information Systems. You can learn more about my scientific work in my curriculum vitae downloadable as PDF. My ORCID iD is http://orcid.org/0000-0002-2091-389X and I have a Google scholar profile.
I worked in several companies that I founded or co-founded. Semantic technologies were made a business with our startup “Ontonym – passendes einfach finden”. Research oriented services such as conference organisations were provided by my spin-off is-research GmbH.
