    Computational Metaphysics and The Ontological Argument:
Latest news: My lecture concept on Computational Metaphysics won the central teaching award of Freie Universität Berlin. The lecture will be held in summer 2016 (lecture course proposal and website/schedule).
Visitors of my website are often interested in my recent work (in collaboration with Bruno Woltzenlogel Paleo) on the verification and automation of variants and emendations of Kurt Gödel's ontological argument for the existence of God. This work had a media repercussion on a global scale. There are various articles (e.g., Spiegel Online Intl., Die Welt, Wiener Zeitung, Spiegel Online) and interviews (e.g., Telepolis, PC Zoznam, Detector.fm, ORF); a selection of further links to reports worldwide is available here. Unfortunately, and probably unavoidable, there are also a few ill informed, trashy reports like this one. If you want to learn more about our scientific work (and about what we did and what we didn't), then you may have a look at our ECAI-2014 paper. Btw, the experiments reported there can be easily recomputed on various computer platforms; the most convenient way is to use our experiment package at recomputation.org. Further recommended publications include: ArXiv, AFP, and more recently LogicAndReligionCongress. Formalization sources (in Isabelle, Coq, THF, THF-TPI), our papers and various other related material are freely accessible via our github repository.

I am still a passionate middle and long-distance runner. In the early 90's I lived and trained at the Olympic Centre in Saarbrücken. In 1990 I was German Champion with the men's team in cross-country running. Feel free to beat some of my personal records: 2:25min (1000m), 3:49min (1500m), 8:14 (3000m), 14:13min (5000m), 30:04min (10000m). Since 2004 I am occasionally starting again in some street races; here are some recent results. Since around the same time, I have also become an enthusiastic diver. Furthermore, I like skiing.
