About Me

I am a Monash Scholar, currently studying for a PhD in Computer Science at UC Berkeley. My research focus is Natural Language Processing — in particular, developing new methods to analyse errors in parsing, coreference resolution, and machine translation. I am a member of the Berkeley NLP Group, and my advisor is Dan Klein.

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. Since graduating I have continued to collaborate with members of the lab.

I completed my Higher School Certificate at Emanuel School, receiving the Premier's Award for my results in English, Mathematics, Physics, and Cosmology.
