My research explores the cognitive neuroscience of episodic memory using behavioural, eye-tracking, and functional neuroimaging methods. I am particularly interested in how past events are reconstructed during memory retrieval and how brain network dynamics influence this process. My projects ask questions such as: how are multimodal event details integrated and consciously reinstated as a coherent representation? What determines the precision and transformation of our memory for spatial-temporal details over time? How do contextual factors such as emotion modulate episodic retrieval? And how do neural network connections flexibly support these operations?

Ongoing Research Projects

  • Brain network dynamics supporting the quality of episodic memory

    Using fMRI and EEG methods, we are investigating how the hippocampus interacts with cortical networks to support the quality of multimodal episodic memories, and how different memory features are reactivated over time.

  • Temporal event integration and reconstruction

    We are using continuous video and auditory stimuli to investigate the temporal dynamics of event integration and reconstruction, focusing on how parallel streams of information are bound in memory and the neural mechanisms that support the unfolding of these episodic features over time.

  • Qualitative changes to memories as they 'fade' over time

    We often experience the feeling that our memories ‘fade’ over time, but exactly what changes memories undergo as they become weaker are still unclear – do our memories simply lose detail and become more less precise, or can their qualitative features also become transformed? To answer this question, we are running a series of behavioural experiments in which participants reconstruct the visual-perceptual appearance of complex scenes.
