YANG Xiaolu, Professor of linguistics of the Department of Foreign Languages Literatures of Tsinghua University, Director of the Language Acquisition Lab. Her primary research interest is syntactic and semantic development of Mandarin-speaking children and her previous work spans acquisition of various forms and structures in Mandarin Chinese, including focus and scalar particles, functional categories, control structures, classifiers, unaccusativity, wh-questions and so on, using naturalistic observations and experimental methods. Taking a linguistic approach to the study of child language, she attempts to explore the interaction of universal grammar and language-specific grammars as well as the relation between linguistic and cognitive development. Currently she is working on early language acquisition of syntax and semantics in Mandarin-learning toddlers. Her work has been published in international journals and journals in China and also in international conferences such as BUCLD and GALA. She has authored two books and is PI of three projects supported by the National Social Science Fund of China.
