I'm a postdoc working with Dr. Ivan Titov.

I'm interested in neural networks and deep learning. My current work is to employ them to solve natural language processing tasks such as coreference resolution, dependency parsing, semantic role labelling, and sentiment analysis.  I'm also interested in formal semantics, especially learning semantic parsing, which is the topic of my master thesis.
 
I did a PhD at the same university, under supervision of Dr. (Jelle) Willem Zuidema. My promotor is Prof. Rens Bod.
