About Me
I am currently a Research Fellow at Nanyang Technological University (NTU), working with Prof. Wei Yang Bryan Lim and Prof. Cyril Leung in MIDORI Lab. Before this, I received my Ph.D. degree in 2025 from the School of Cyberspace Science and Technology at Beijing Jiaotong University, supervised by Prof. Jiqiang Liu and Prof. Wei Wang. From 2024 to 2025, I was a visiting student at Nanyang Technological University.
My research mainly focuses on Trustworthy AI, with a particular focus on poisoning attacks and defence mechanisms in distributed deep learning systems. Recently, my research has shifted toward trustworthiness in Multimodal LLM and Agent, where I explore potential vulnerabilities and develop robust defence mechanisms to enhance their integrity and user trust.
