data & cognitive science
I'm a part-time Experimental
Psychology PhD Student @ University
and a Senior Data Scientist @ dunnhumby. I'm also an Industrial Fellow
of the 1851 Royal Commission.
I'm interested in human decision-making and the ways it can be improved. My PhD research (in collaboration with Professor Brad Love and dunnhumby) aims to understand how consumers develop preferences for products in the supermarket. I combine experimental psychology, big data analyses and cognitive modelling.
At dunnhumby, I develop and deploy machine learning models at scale. I'm particularly interested in model deployment, natural language processing and reinforcement learning algorithms.
If you would like to get in touch, please email me.
Several in preparation.
