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 embedded system security, home automation system security and other hardware security, especially for hard drive. 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. My strengths include circuit design, PCB design and embedded system development. I am currently working on acoustic attacks on hard drives and security protocols for smart homes.
