The Department organized a Homecoming event on 5 November 2022 to celebrate PolyU’s 85th Anniversary. The event was supported by the Alumni Association of Electronic and Information Engineering (AAEIE) and the Electronic and Information Engineering Student Association (EIESA). More than 20 alumni came back to their alma mater with their family members together for reunion. They were welcomed by Prof. M.W. Mak, Interim Head of Department, and Mr Dominic Tse, AAEIE Chairman. Prof. Mak introduced the latest development of EIE, while Mr Tse shared about the AAEIE activities with the participants. A laboratory tour was guided by the EIESA committee members for the guests to visit the PolyU-Innovation Technology (HK) Audio and Speech Signal Processing Joint Laboratory, PolyU-Huawei Joint Laboratory for Optical Interconnection Network and Advanced Computing System, Information Security Laboratory, and Microfabrication Laboratory. Our graduates enjoyed this event very much to tour around the EIE facilities with state-of-the-art technologies and to catch up with the professors and their classmates.
