About Me

I am a Postdoctoral Research Fellow, working at the University of Michigan, in Computer Science and Engineering. My research focus is Natural Language Processing — in particular, I am working on Project Sapphire, a collaboration with IBM, developing a conversational academic adviser. I am also a member of two research groups: Computational Linguistics And Information Retrieval, and Language and Information Technologies.

I completed my PhD in the Berkeley NLP Group in 2016, advised by Dan Klein, with a thesis on new algorithms for syntactic parsing. I graduated from the University of Sydney with a Bachelor of Science (Advanced) with First Class Honours and Medal in Computer Science in 2009. For my honours thesis, "Adaptive Supertagging for Faster Parsing", I studied in the Schwa lab, advised by James Curran. I received my Higher School Certificate at Emanuel School, receiving the Premier's Award for my results in English, Mathematics, Physics, and Cosmology.
