I'm a member of the NLP group in the Department of Computer Science at Sheffield University, where I work with the GATE team.

My research interests are social informatics, social media analysis, big data, web science, data mining.

Here's the GATE blog, where we talk about our work in this area, including our recent work on online misinformation.
