I'm an assistant professor at the University of Warwick. My research revolves around Human Factors in Natural Language Processing, which involves interdisciplinary research in NLP and HCI, furthering understanding and methods for the analysis of text and conversations online with an awareness of how people interact with information as well as with one another. Examples include leveraging online data (social media, web, open data) to model, track and understand real world phenomena, and furthering approaches to mitigate the vulnerabilities of the Web and social media, such as hate speech, misinformation and inequality. My work involves research in natural language processing, social media mining and computer-supported cooperative work, amplified by an interdisciplinary perspective involving social sciences such as journalism, sociology and psychology. I've published over 80 peer-reviewed publications, including 25+ journal publications. According to Google Scholar, my research has been cited over 1,200 times, with an H-index of 21 (as of September 2018).

I'm currently the module organiser for CS918 Natural Language Processing, and previously was a module co-organiser for CS909 Data Mining at Warwick. I'm also teaching social media mining (in Spanish) as an external collaborator at UNED's online MSc course in Human Language Technologies.

I'm open to collaboration, do drop me a line if you're interested in discussing.
