Li Chaohao


My name is Chaohao Li and I’m a Ph.D. student at the College of Electronical Engineering, Zhejiang University. As part of the research team in the Ubiquitous System Security Lab, my research spans IoT security, AI security and Analog security. I’m committed to explore the vulnerabilities of Internet of Things (IoT) or other hardware and then try to build the defense mechanism for them.
