Data Science

Data Science studies the tools and methods to organise and process data sets. As data sets become larger and more interconnected, they carry a greater potential for detecting patterns that prove useful for science, industry, and healthcare. Yet large sets of complex data, often composed of both structured and unstructured data, also present significant challenges with regard to organising, storing, and processing them.

The Data Sciences Research Group studies the use of large databases, distributed databases, and cloud computing. We also develop and adopt various methods including evolutionary computing, statistical methods, visualisation, agents, pattern recognition, and machine learning.

Our work and that of our postgraduate students directly informs our teaching in the Master of Business Data Science (MBusDataSci).
