Rex Parsons

I’m currently a Senior Data Scientist at Nous group.

In my recently completed PhD at AusHSI (QUT), I worked on prognostic models for inpatient falls using electronical medical records and developed software to evaluate/optimise clinical prediction models from a health economic perspective. At Nous, I spend most of my time either analysing health data for large healthcare evaluations or developing Shiny apps and R packages for both client facing or internal use.

In general, I enjoy learning new things, programming with R, and applied problems relating to healthcare and biomedical research.

Outside of work, I enjoy riding motorbikes, filter coffee and strength training.
