Qianchu(Flora)Liu

I am a final year PhD student in Computation, Cognition and Language at the University of Cambridge. I am a member of the Language Technology Lab (LTL), working on computational models of lexical representation in context and multilingual NLP. My supervisors are Professor Anna Korhonen, and Dr. Diana Mccarthy. I am a member of Peterhouse College and I am funded by Peterhouse Research Studentship.
