Profile

Biography

I am a Lecturer at the University of Essex. Before that, I was a post-doctoral researcher at the Queen Mary University of London, working with Professor Matthew Purver on the EMBEDDIA and SoDeStream projects. I obtained a Ph.D. at DISI, the University of Trento. I was supervised by Dr. Raffaella Bernardi, University of Trento, and co-supervised by Prof. Raquel Fernández, University of Amsterdam. My research interests include Natural Language Processing, Cross-Lingual Representation, Language and Vision Interaction, and Social Media Analysis.
