Wei-Fang is a third year PhD student in the Department of Linguistics at Harvard. Her main research areas are syntax, semantics, the syntax-semantics interface and laboratory phonology. Her research interests include the syntax and semantics of reduplication, ellipsis and resultatives, and the phonetics and phonology of tone sandhi. Wei-Fang uses experimental methodology to investigate the tone sandhi pattern in Mandarin-English code-switching context. She seeks to relate the empirical data collected using experimental methods to the phonological theory. In particular, her current phonology project investigates how the phonotactic differences between Mandarin and English may have a distance effect on the application of tone sandhi in speech production of Mandarin native speakers code-switching between the two languages. Before coming to Harvard, Wei-Fang received her M.A. in Linguistics and B.A. in Foreign Languages and Literatures from National Chiao Tung University, Taiwan.
