About me

I am a second 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 knowledge graph, commonsense reasoning and text classification. Also, I do some research about text generation. I focus on using AI to solve practical problems.
