Chi-kiu, LO received her Master of Philosophy (MPhil) in Computer Science and Engineering in 2009 and Bachelor of Engineering (BEng) in Computer Science (minor in Social Science) in 2004 from the Hong Kong University of Science and Technology (HKUST). She is currently pursuing her Doctor of Philosophy (PhD) degree in the Department of Computer Science and Engineering, HKUST under supervision of Prof. Dekai, Wu. Her research interest is statisitcal natural language processing with particular focuses on machine translation and semantic role labeling. She is experienced in instructing computer science courses of different levels, rangeing from computer literacy for non-CS undergraduates, fundamental programming for non-CS undergraduates, advanced programming for junior CS undergraduates, artificial intelligence and natural language processing for senior CS undergraduates, knowledge management for IT taught postgraduates and natural language processing for CS research postgraduates.

Research interests

Semantic Machine Translation Evaluation; machine translation; semantic analysis of text; statistical natural language processing; text mining; machine learning and data mining; customer relation management (CRM).
