The goal of my research is to understand the meaning in text and speech (semantic analysis), in order to automatically generate language that is fluent and appropriate to the context. This involves observing statistical patterns of language use, and then developing algorithms that can automatically reason with these statistically derived meaning representations (distributional semantics). The reasoning and inference component can then be used in language generation applications, such as in automatic summarization.
Topics in computational linguistics that I have published on include computational semantics, parsing and discourse analysis, and automatic summarization.
I was supported by a Facebook Fellowship for 2013–2014.
News: I am starting as an Assistant Professor in the School of Computer Science at McGill University in January, 2015! I will be looking for motivated and qualified students who are interested in undertaking research in computational linguistics.
