Biography

I am a Lecturer (Assistant Professor) at the School of Computer Science and Informatics at Cardiff University. I lead the CardiffNLP group and am also a Visiting Academic at the University of Cambridge.

Previously, I was a Postdoctoral Research Associate at the University of Cambridge, working with Andreas Vlachos. I completed my PhD at the Hong Kong University of Science and Technology (HKUST), where I was supervised by Yangqiu Song and Dit-Yan Yeung.

My research focuses on Natural Language Processing and Computational Social Science, particularly in automated fact-checking, toxic content detection, and low-resource languages.
