I am a linguist with mathematical background. I was educated in Germany, France and Australia and appointed as professor at City University of Hong Kong before moving to Shanghai in 2019. I am interested in mathematical linguistics, in typology and in the languages of Southwest China. I am currently consultative editor of "Linguistics" (Mouton de Gruyter, Berlin) and was a fellow of DAAD (Germany), and a member of the advisory board of the "Institute of Linguistics" (Academia Sinica, Taibei).
