Moin, I'm Jan. In my volunteer capacity, you can find me as Jan eissfeldt. I started contributing to Wikipedia - first and foremost to its German language version - in March 2004 and tend to edit topics related to philosophy of language, logics, macroeconomics, and philosophy of science in English, German or Spanish. However, you may also encounter me working on articles concerning philosophical aspects of the differences between common and civil law; an issue heavily interacting with my preferred academic pet: argumentation theory.

My foundation role is to help the WMF to organize and improve strategic and programmatic planning and operations.
