Understanding the Digital Society

Digital Society

Digital innovations are reshaping our society, economy, culture, and lifestyle. Their ability to impact – and potentially advance – all aspects of our society cannot be overstated, resulting in a need for vigorous interdisciplinary research, from the application of digital innovations to benefit our daily life to a thorough understanding of the relationship between digital progression and society.

Multidimensional data is an important part of “big data”, which is a buzzword for the unprecedented development of internet and communications systems, and computing and mobile devices in the digital era. While big data promises great potential, fundamental mathematics and computing concepts are still being actively developed and hotly debated.
Professor Hong Yan, chair professor of Electrical Engineering, is leading research examining mathematical models and computer algorithms for a computing model – tensor computing – and its application in multidimensional data analysis, and image and biomedical data analysis.


One of his projects uses biomedical data to look into the causes of drug resistance in lung cancer cases with the aim of personalizing treatment.
In the digital age, privacy, trust, and security are some of the key concerns for online activities and platforms. Researchers from the field of computer science at CityU are leading a collaborative research project, which includes experts from other universities in Hong Kong, to develop new security and privacy-enhancing technologies for cloud storage to enable users to search encrypted data, verify results from data analytics and safely access cloud services.


Academics from the department of information systems are beginning research related to blockchain technology, extending its uses beyond banking and financial services, from encrypted keyword searches to information security in the food supply chain system.
CityU scientists are leading interdisciplinary research to understand the impact of digital technology on society. Dr. Ayoung Suh, a social scientist in the School of Creative Media and the department of data systems, is exploring how people’s virtual experience using media technologies affects their attitudes, thoughts, and behaviors, such as “nomophobia” – the stress of being without a mobile phone.

City University of Hong Kong’s digital technology research Digital Society


The first data science school and research institute in Hong Kong

In reply to the increasing demand for data scientists and engineers, CityU started the School of Data Science and the Hong Kong Institute for Data Science.

The first such freestanding academic unit concentrating on data science in Hong Kong, the SDSC serves as a campus-wide educational resource, fostering collaboration and training high-caliber students from data science-related industries.


The HKIDS serves as a hub for joint research to tackle challenging problems in data science.

These actions reflect CityU’s strategic development to meet the demands of a data-driven economy now and in the future.
