My research uses both neuroimaging (fMRI, DTI) and neuropsychology to investigate brain networks underpinning human memory and perception. In particular, our research focuses on how the brain represents specific - and evolutionary relevant - categories, such as faces and scenes. Our ultimate aim is to understand how these neural circuits are affected in ageing, dementia, and neurological disease, and to identify imaging biomarkers in individuals at increased risk of later-life cognitive decline.
I have previously supervised both MSc and undergraduate projects, and have co-supervised several doctoral students. In terms of teaching, I have delivered level 2 statistics practicals and have marked undergraduate assignments and final year projects.

Research topics and related papers
Currently, I am working on a project investigating the memory and perception of young, healthy individuals who possess a genetic risk factor for Alzheimer’s disease (AD). Previous research suggests an overlap between the brain regions implicated early on in AD and those active during spatial processing in healthy participants. As individuals with AD also show impairments on spatial/scene memory, this research investigates whether those individuals at genetic risk show differential activation in those regions that have been marked in both spatial memory and early on in AD.
Similarity and conceptual knowledge
Another aspect of my research focuses on what makes things similar. Specifically, I am investigating a new theory of similarity based on the number of transformations between object representations. Transformations are an important part of our visual and conceptual experience; objects and scenes transform continuously as we move about the world, organisms transform in principled ways, and man-made artefacts deteriorate over time. Our goal is to understand how transformational relationships, through their real-world prevalence, serve important cognitive and conceptual functions.

I was awarded my undergraduate degree (BSc Psychology, 2.1) from Cardiff University in 2006. During this period, I worked as a research assistant with Professor Ulrike Hahn where I programmed and developed cognitive tasks.
Following on from my undergraduate experience, I was awarded a joint School of Psychology/EU funded studentship to undertake a PhD in Cognitive Science at Cardiff University. During this time, I worked with Ulrike Hahn and Nick Chater, exploring the relationship between similarity, categorisation and object representation (Hodgetts, Hahn & Chater, 2009; Hodgetts & Hahn, 2012).
