Department of Electronic and Information Engineering

Doctor of Philosophy / Master of Philosophy

Sept 2019 Entry


Electronic Engineering at PolyU dates back to the early 1970s. In the 1980s, the Department of Electronic Engineering was one of the first academic departments in Hong Kong to introduce research and teaching in this field. Since then, the Department has gone through an exciting course of development, rapidly becoming one of the leading departments in selected fields of Electronic and Information Engineering worldwide.


The Department of Electronic and Information Engineering (EIE) aims to solve complex problems with innovative ideas and to produce high-impact research that is relevant to industry and society. Major research endeavours within the Department are conducted within four research groups. The foci of these groups are nonlinear circuits and systems (including power electronics, wireless power transfer technologies, renewable energy systems, LED lighting systems and complex networks), communications (including optical and wireless communications, vehicular communications, channel coding, optical sensor systems), signal processing and artificial intelligence (video and image coding, speech and pattern recognition, artificial intelligence and machine learning) and photonic systems and devices (information optics and photovoltaic devices). Other research topics include information security, bio-inspired optimisation techniques and forensics. Currently, over a hundred funded research projects are being undertaken. These projects are funded by the Hong Kong government, the Chinese government or our industrial partners such as Huawei Technologies and PCCW/HKT. Most of the Department’s research students will receive financial support during their PhD study. Every year, a few candidates nominated by the Department will be awarded the prestigious Hong Kong PhD Fellowship (HK$20,000 per month studentship).


Applications are now invited for registration on our full-time programme leading to the Degree of Doctor of Philosophy (PhD)/Master of Philosophy (MPhil) by research in EIE. Please browse the e-prospectus to learn more about our research degree study programmes and EIE research interests.


We very much look forward to welcoming you to EIE!
