Wei Song

I am a fourth-year PhD student in Compiler Optimization Research Group (CORG) at Computer Science and Engineering school of UNSW Sydney (UNSW/CSE), supervised by Scientia Professor Jingling Xue. Before joining CORG, I received my Master in Information Technology at UNSW/CSE. My research interests lie at the adversarial attacks/defenses in deep learning, and security in IoT Systems.
