Liang Zhou is a full professor of School of Electronic Information and Electrical Engineering, Shanghai Jiao Tong University. His main research interests include Microwave and Millimeter wave Passive/active Components, RF system on packaging (SOP) design and modeling, EMC and High Power Microwave (HPM) protection of communication platforms, and multi-physics and its application.

Heterogeneous 3-Dimensional Integration is his first interest. He proposed several ideas of heterogeneous integration methods by incorporating active components, such as silicon, GaAs, or even GaN transistors using benzocyclobutene (BCB)-based polymer dielectric fabrication process. He also investigated some miniature RF passive components for SOP. Reliability issues of high-density devices in the system have also been examined through electro–thermal–mechanical (ETM) analysis using multi-physics methods.
Another interesting research area is investigations and demonstrations of electro-thermal or even stress breakdown of RF semiconductors caused by high power microwave pulses (intentional Electromagnetic Interference). The temperature and stress distributions and transient performance of the LDMOS FET and GaN HEMT are able to be characterized by using their own developed time-domain finite-element numerical algorithm. Further, he also developed some protection circuits and methods to evaluate the immunity of the low-noise amplifier (LNA) and help to decrease the susceptibility of the semiconductors.
