About

I am a Machine Learning Researcher at Apple's Machine Learning Research (MLR) team, led by Samy Bengio, in Cupertino, California. I obtained my PhD from the University of Amsterdam, where I worked with Maarten de Rijke and Julia Kiseleva. I completed my MSc in Artificial Intelligence, and my BA in Linguistics, at the University of Amsterdam and partially at the University of Edinburgh.

I am broadly interested in Human-Centered NLP, that is, centering the design and development of natural language technology around humans. My research is mostly motivated from two angles, roughly summarized as: (i) who are the users of NLP systems, and what do they want?, and (ii) how can we use our knowledge of human language processing and acquisition when developing these NLP systems?

You can find my CV here.
