Data Analytics


Asia is an integral part of a world immersed in service systems that are often large and complex. In this era of information explosion, an enormous amount of data has been collected by organizations for various reasons and there is great potential to harness this data to improve individual, organizational and societal well-being.

Analytics deals with the study of data with the aim of discovering new and useful information, validating/refuting existing hypotheses, and creating realistic data-driven mathematical models that facilitate complex decision and policy making.  It empowers stakeholders with the knowledge and tools to make informed and timely decisions in a complex environment with risk and uncertainty.   

Data Analytics @ GAI explores the integration and development of state-of-the-art analytics with the goal of understanding and addressing relevant and important issues in Asia such as healthcare services and costs, and life cycle financing, among others. It aims to foster inter-disciplinary research that leverages analytics expertise within NUS.

At present, data analytics at GAI is represented by an initiative called HEARTS (Healthcare Analytics Research and Technologies), led by Prof Melvyn Sim of the NUS Business School. Please go to the HEARTS homepage to learn more.
