Huw is a Research Fellow at the Turner Institute for Brain and Mental Health in the School of Psychological Sciences, where he studies reward, motivation, and decision-making processes in the brain, and how these might be disrupted in neurological and psychiatric disorders. He uses a range of methods to investigate this topic, including behavioural experiments, pharmacological interventions, studies in clinical populations (e.g. Parkinson's disease, depression), neuroimaging (e.g. fMRI), and mathematical modelling of cognition.

Huw completed his PhD at Monash in 2024, investigating the computational mechanisms underlying effort and reward valuation in the human brain. In 2021-22 he was a Fulbright Scholar at Yale University, where he worked on models of momentary mood and motivation based on data collected remotely from smartphones. Prior to this, he worked in research translation at the National Health and Medical Research Council (NHMRC) of the Australian Government (2016-17), and undertook 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).
