Ir Sheldon Yau Siu-lun has been a leader in mobile technology advancements in Hong Kong for over three decades. Since the early 1990s, he has helped pioneer innovative features for mobile networks such as mobile coverage in subways. These innovations have helped expand and improve mobile phone coverage in Hong Kong. As mobile networks evolved from traditional voice to data services in the late 1990s, Ir Yau designed antennas that could work with different radio frequencies. In the 2000s, Ir Yau helped set up one of Hong Kong's first 3G mobile networks, which involved changing the way mobile signals were transmitted. His master's degree from PolyU was valuable during this time. In the 2010s, when 4G networks were introduced, he tackled challenges such as using more radio frequencies and combining signals from different frequencies. He also applied technologies from fixed-line networks to improve mobile networks. Subsequently, Ir Yau led a project to consolidate the PCCW and CSL networks. In 2020, he helped HKT launch Hong Kong's first 5G network. Ir Yau is currently working on advanced 5G technology, AI, and ways to use mobile technology for the emerging low-altitude economy. His goal is to keep HKT at the forefront of innovation. He hopes to continue contributing to the progress of the mobile communication industry in Hong Kong and around the world.

Dr Mai Weijie received his Bachelor of Engineering with first class honours from The University of New South Wales, Australia in 2012, and his Doctor of Philosophy from PolyU in 2017 as an awardee of the Hong Kong PhD Fellowship Scheme—both in electrical engineering. In 2020, he was also recognised as Overseas High-Caliber Personnel under the Shenzhen Peacock Plan. Dr Mai currently serves as Vice President of Shenzhen Auto Electric Power Plant Company, Limited—a listed, state-recognised high-tech enterprise.  The company, established in 1993, designs, develops, manufactures, and operates high-power industrial charging equipment. He is responsible for managing the daily operations of the Department of New Energy, overseeing various divisions. His primary objective is to ensure smooth and efficient operations across all divisions while driving the company's strategic initiatives in new energy. Dr Mai and his team have significantly impacted the new energy industry by contributing to the development of the groundbreaking Mega-Watt Adaptive Charging Power Pool, and the establishment of an Electric Vehicle (EV) Ultra-Fast Public Charging Network with a capacity of 235MW across China. Dr Mai’s achievements exemplify a commitment to building safer, greener, and more efficient charging solutions. These efforts minimise the use of valuable public resources such as land and power, marking a notable step towards a sustainable EV charging infrastructure.
