General Information

It is common to polish the publication list by putting conference contributions which are published in a book-like format together with real contributions to books. In my opinion this is misleading and therefore I am not following this approach here. Since I do not have a real contribution to a book yet, I simply distinguish between journal articles, conference proceedings, research commentaries, manuscripts which are submitted and theses (PhD and diploma).
