I'm an applied scientist at Amazon. I did a postdoc with Ivan Titov at the University of Amsterdam and the University of Edinburgh. I got a PhD from the University of Amsterdam under the supervision of (Jelle) Willem Zuidema. 

I'm interested in neural networks and deep learning. My current work is to employ them to solve natural language processing tasks such as entity linking, coreference resolution, and dependency parsing.  I'm also interested in semantic parsing, which is the topic of my master thesis.
