About

I investigate the neural correlates and behavioural mechanisms that underpin how people apply physical effort to avoid unpleasant situations. I am also interested in computationally modelling biases and affective states that contribute to evaluations of effort cost, with the aim of better understanding the roles that differing cognitive mechanisms play in people’s perception of effort. I am supervised by Dr. Rebecca Todd and Dr. Alan Kingstone, and also collaborate with Dr. Kiran Soma and Dr. Tim Murphy.

Research

I’m interested in the cognitive processes and neural representations underpinning how people learn to avoid unpleasant outcomes and approach pleasant ones, from the perspectives of behavioural tasks, neuroimaging, and computational modelling. Separately, I also collaborate on a variety of fMRI data analysis projects; develop statistical models of glucocortioids in mouse brain and immune tissues; and help develop computer vision methods for closed-loop mouse behavioural analysis and mesoscale calcium imaging of mouse cortex.
