I am currently a PhD student at The University of Queensland (UQ), supervised by Helen Huang and Xue Li. I obataied my Bachelor of Law (LL.B.)⚖️ and Master of Law (LL.M.)⚖️ degrees in 2018 and 2021 respectively.
My research focuses on artificial intelligence in legal domain, including legal case retrieval and graph neural networks for legal cases etc.
I speak Cantonese, English, and Mandarin.
