I commit myself to the guideline for safeguarding good scientific practice and distance myself from all varieties of so-called conspiracy ideologies.

I am not  affiliated with any religious or ideological association and  distance myselve from any kind of racism, anti-semitism, sexism and other extremist attitudes. Freedom (of opinion), access to information, tolerance, democracy and hospitality are very important to me.
