Summary

My research looks at the role of dopamine in reinforcement learning and memory, and I test Parkinson's Disease patients, varying their medication states in order to affect the level of dopamine in their brains. I also fit computational models of reinforcement learning to the patients' data, in order to see whether dopamine medication changes parameters of the models when fit to data.

 

Biography

I completed my BSc. (Hons) in Psychology and the University of York, before starting my PhD in Neural Dynamics.

Activities / Findings

I completed my PhD in Neural Dynamics at the University of Bristol, and my BSc in Psychology at the University of York. My PhD work focused on the roles of dopamine in human memory, using psychological testing of human Parkinson's disease patients on several reinforcement learning and memory tests. I also used computational modelling of their behaviours on the tests to investigate the mechanisms behind dopamine's effects on memory.

My current work looks at the role of genetic polymorphisms in dopamine-related genes (e.g. receptor genes, enzyme genes) in human memory across different ages.
