I am a senior lecturer (associate professor) at Queen Mary University of London, where I co-lead the Social Data Science lab and I'm Director of Graduate Studies. I'm also part of the leadership team of the Centre for Human-Centred Computing.
My research lies in the intersection between Computational Social Science and Natural Language Processing. I'm broadly interested in furthering NLP and LLM methods for processing social media and Web data, with a key focus on tackling problematic issues that can have a damaging effect on individuals or society at large, such as hate speech, misinformation, inequality, biases and other forms of online harm. I'm also interested in detecting and addressing irresponsible use of AI, where LLMs are used for malicious purposes such as misinformation and abusive content, for augmenting existing societal biases or for producing content that is claimed to be human generated. Check out my research interests for more.
I have published 180+ papers, including 60+ journal articles, in some of the most selective venues including ICWSM, WWW, ACL, EMNLP, EACL, NAACL, COLING, SIGIR, CIKM, and a wide range of selective journals.
I'm currently involved in the HYBRIDS MSCA Doctoral Network (PI).
