Jiazheng Li

I am a first-year PhD student at the University of Warwick in the Department of Computer Science, under the supervision of Prof. Yulan He and Dr Lin Gui. My research focuses on natural language processing (NLP) and pays particular interest in language model interpretability. I am also the 1st Year representative of the Computer Science PGR SSLC.

Prior to joining Warwick, I obtained my bachelor’s degree in computer science with First-Class Honours from the University College Dublin in 2021. I completed my final year project under the supervision of Prof. Pádraig Cunningham.

In 2020, I worked as a data scientist under the lead of senior data scientist expert, Dr Ying Wu at SAP Ireland. During my undergraduate study, I worked as a research assistant at the Science Foundation Ireland's Insight Centre for Data Analytics for two years. I conducted NLP research under the supervision of Prof. Barry Smyth and Dr Ruihai Dong, and signal processing research under the supervision of Dr Andrew Hines.
