Sleep Memory

sleep and episodic memory reorganisation

How does deep sleep reshape our memories? Our new study shows that slow-wave sleep (SWS) reorganises episodic memory networks, shifting recall from the parietal cortex to the anterior temporal lobe (ATL).

Visual-Semantic Brain Abilities

individual differences in visual-semantic brain representations

We explore how inter-individual differences in visual (face) cognition relate to visual and semantic representations in the brain, combining EEG decoding, behavioural metrics and representations in vision and language computational models.

Visual Content

visual content behind face representations

This line of work maps the content of visual representations across different face recognition tasks using "reverse correlation" psychophysical techniques.

EEG-fMRI Fusion

spatiotemporal fusion of EEG and fMRI

By combining EEG and fMRI, we uncover the spatiotemporal code the brain uses to represent visual objects. This fusion approach captures the millisecond-level dynamics underlying high-level visual processing.

about me

human memory | vision | sleep | EEG | Intracranial EEG | fMRI | deep learning

My research focuses on understanding how the specific content of our perception and experiences guides our behaviour, with a specific focus on visual recognition and episodic memory. I'm interested in characterising how our internal representations — such as visual information about objects and faces — are supported by the brain, how idiosyncrasies in behaviour (e.g. memorisation ability across individuals) affect these representations, and in understanding how the specific content our mind represents (e.g. visual or concept-like information from an every-day scene at the office) is transformed with the learning of new memories, specifically during sleep. To understand these processes, I use a combination of behavioural and brain imaging techniques (electroencephalography, functional MRI, EEG-fMRI) as well as machine learning to probe brain representations in a range of different individuals.

During my Postdoctoral research (University of Oxford, Staresinalab), I am tackling questions related to the neural code of episodic memories as they are transformed during sleep.

I was funded by a Newton International Fellowship from The Royal Society (2023-2025). I am currently a Banting Postdoctoral Fellow in the Department of Experimental Psychology at the University of Oxford, and a Junior Research Fellow at Wolfson College.
