Disclosure: Beginning in 2015, I am working for the United Nations University Institute on Computing and Society (UNU-CS). I edit related articles with my free time following the practices to avoid potential conflict of interests (i.e. using mainly secondary sources, full disclosure, etc.).
I am a user of Wikipedia (zh and en). My reasearch is on the comparative study of Chinese Wikipedia and Baidu Baike. Thus, my contribution to Wikipedia projects is mostly limited or indirect.
