Yiwei Si

Hello! My name is Yiwei Si. I’m currently a third-year PhD student in Linguistics at the Faculty of Linguistics, Philology and Phonetics at the University of Oxford. I’m fortunate to be supported by both the Clarendon Scholarship and the Hanseatic Scholarship for my doctoral research. As part of the Hanseatic Scholarship, I’ll be spending a year as a visiting researcher at the Leibniz-Centre General Linguistics (ZAS) in Berlin, starting in October 2025.

My main research interest lies in morphology and its interfaces with phonology, syntax, and semantics. In my DPhil thesis, I explore how verbal particles in German contribute to the expression of aspect from both syntactic and semantic perspectives, using a neo-constructionist approach to word formation. I’m additionally interested in syntax, psycholinguistics and first language acquisition.

Before starting my PhD, I completed an MPhil in Linguistics at Oxford in 2022. I earned my Bachelor’s degree in German Studies from Beijing Foreign Studies University in China.

Outside of linguistics, I enjoy exploring local restaurants, practicing yoga, playing tennis, and travelling.
