Lecturer (Assistant Professor)

OusidhoumN (at) cardiff (dot) ac (dot) uk
Office 5.50 Abacws building, Cardiff.

I am a Lecturer (Assistant Professor) at Cardiff University and a Visiting Academic at the University of Cambridge. Prior to this I was a Postdoctoral Research Associate at the University of Cambridge advised by Andreas Vlachos. I did my PhD at the Hong Kong University of Science and Technology (HKUST) under the supervision of Yangqiu Song and Dit-Yan Yeung.

I am interested in automated fact-checking, toxic content detection and evaluation in NLP, and NLP for low-resource languages. For more information, you can check my curriculum vitae and my Google Scholar.
