My primary research goal is to define the cognitive and functional impacts of obesity and nutrition on the brain. This research program has immediate relevance to a growing public health issue in Australia, where nearly a third of all children, and two-thirds of all adults, are overweight or obese. I use a multidimensional approach involving cutting-edge behavioural and neuropharmacology paradigms – including transgenic mice (Cre-lox, KI and KO models), in vivo fiber-photometry, chemogenetics, and optogenetics to study cognition and the functional effects of simulated ‘junk food’ diets in rodents; combined with molecular and chemical profiling of the post mortem rodent brain. This framework spans from individual gene expression, neurochemical alterations of neurons and their surrounding extracellular components (perineuronal nets), to long-lasting effects on neurodevelopment to provide a comprehensive picture of the neurobiological impact of obesity from the micro- to macro-scale.

I have built a strong reputation as an emerging thought leader in neuroscience and nutrition fields, demonstrated through numerous grants, awards and speaking invitations.
