I am a postdoctoral researcher at Queen Mary University of London. My current focus is on label aggregation techniques and the training of models on data with disagreements.

I am part of the DALI project, in charge of the analysis of the annotations collected using Phrase Detectives, a GWAP (game with a purpose) developed for gathering labels for coreference resolution, with over 5 million judgements collected.


[!!] A book on Statistical Methods for Annotation Analysis is to be released, in collaboration with Ron Artstein and Massimo Poesio. This is going to be part of the Synthesis Lectures on Human Language Technologies (morganclaypool.com) series.

[!] A tutorial on aggregating and learning from multiple annotators has been accepted at EACL 2021. More details on its website. You can watch the recorded video here.
