About me

My broad interests are in the intersection of computational linguistics and statistical learning. I am interested in developing ways to computationally reason about structured objects. Such structured objects are prevalent in natural language processing, for example, in syntactic analysis.

Much of my research has relied on capturing the syntax of natural language using probabilistic grammars -- grammars that originate in linguistics and formal language theory, and that have been augmented with a probabilistic interpretation. My most recent work treats the problem of predicting syntactic structures from text using spectral methods (in the supervised or unsupervised settings) and other linear algebraic methods. Most recently, we applied these ideas to machine translation and to social media.

We recently organised a workshop about vector space modelling in NLP at NAACL 2015 (workshop's website with post-workshop materials and pictures).
