Biography
I joined Durham University as a PhD student in Nov 2019. My research interests are Knowledge Representation Learning (KRL) and its application in different domains. I mainly aim to investigate how to enhance the representation learning ability of models and I have applied them in various tasks including medical vision question answering, natural language processing, financial investment, social network and structural learning of molecules. I demonstrated two modules: Bias in AI and AI Search for undergraduates in the Spring term 2022.
I am also a member of the Alan Turing Institute Knowledge Graph Interest Group and currently working on a UKRI project as research assistant, in charge of developing chatbot. If you are interested in collaboration in any capacity, do not hesitate to get in touch.
