I am currently a research fellow in the Cognitive Neurology Lab led by Dr. Trevor Chong at the Turner Institute for Brain and Mental Health, Monash University, Australia.

My research focuses on the interaction between effort and reward signals in the human brain, and how these signals may be disrupted in neurological and psychiatric disorders. I use a range of methods, including behavioural experiments, pharmacological interventions, studies in clinical populations (e.g. Parkinson's disease, depression), neuroimaging (fMRI), and computational modelling of cognition.

In 2021-22 I was a Fulbright Scholar in the lab of Dr. Robb Rutledge at Yale University, where I worked on computational models of momentary mood and motivation based on data collected remotely from smartphones.

In 2016-17 I worked at the National Health and Medical Research Council (NHMRC) of the Australian Government, assisting with the translation of research findings into clinical practice guidelines and public health policy.

I have also undertaken internships at the World Health Organization headquarters in Geneva (2015), at the Grattan Institute in Melbourne (2015), and at Akim Oda Government Hospital in Ghana (2013).

I am interested in bringing computational tools out of the lab and into the clinic to improve treatment for people with psychiatric and neurological disorders.
