About Me

I am a final year PhD student at University of Liverpool supervised by Prof Bollegala Danushka and Dr. Bei Peng. Prior to that, I obtained Master degree with Distinction from University College London and Bachelor degree with First Class from University of Liverpool.

My main research interests include commonsense reasoning and text diversification. Also, I do some research about RAG. I focus on using AI to solve practical problems.
