<h3>Current Research</h3>
<p>Most of my current projects involve enhancing deep parsing with
statistics, specifically using the <a
href="http://wiki.delph-in.net/moin/PetTop">PET</a> <a
href="http://hpsg.stanford.edu/">HPSG</a> parser. In October, 2011 I moved
to the University of Oslo to take up a postdoctoral position on the
WeSearch project. Previous to that, I was employed for two years on the
OLE project (Online Linguistic Exploration: Deeper, Faster, Broader
Language Documentation) at the University of Melbourne, where my main role
was to produce large amounts of multilingual parsed text. Both project
have involved looking at supertagging configurations that can prioritise
robustness or efficiency. I'm also looking at using statistical
information to improve parsing of under-resourced languages, through
developing methods of training statistical models without manual
annotation.
<p>I have a few side projects involving parser evaluation, looking at
questions regarding how deep parsers should be evaluated, what is common
between different frameworks, and what these differences mean in practice.
