I am currently a Ph.D. student at the School of Computing, Macquarie University, Australia. Supervised by A/Prof. Jia Wu and Prof. Jian Yang. I hold a Master's degree in Information and Technology from the University of Queensland, Australia. My research interests include social event detection, graph neural networks, hyperbolic space representation, and heterogeneous information networks
