Biography
I am a Ph.D. candidate at [Singapore Management University] , supervised by [Prof. Guansong Pang].
My research interests are in graph representation learning, graph retrieval augmented generation, graph anomaly detection and large graph modeling, with a special focus on generative model on graph, graph foundation model.
I feel excited to work with colleagues at Machine Learning & Applications (MaLA) Lab , we investigates novel machine learning techniques, with a research theme focused on abnormal/unknown
data instance detection and generalized learning algorithms for creating trustworthy continual AI systems.
[Job searching !!] I'm looking for a summer 2025 internship opportunity in the US, focusing on large language models, graph learning, or anomaly detection, feel free to contact me (hezheqiao[at]gmail.com, Linkedln, or WeChat ) if you have any job recommendations.
