Centre for Big Data Research

My research focuses on answering questions related to health and healthcare. I apply statistical and machine learning methods to large electronic health record datasets to identify and explore outcomes for patient groups, improve patient care, and streamline clinical processes.

As part of of the MSc Health Data Science, I currently coordinate and teach the course 'Machine Learning I' (HDAT9500) and I am currently designing and creating the content for 'Machine Learning II' (HDAT9510).
