How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I'm a postdoc in the lab of Prof. Stefan Treue and study how social information impacts perceptual decisions in dyadic settings. Specifically, my work addresses where/how the brain incorporates information that becomes available by observing and interpreting the choices and actions of others. My research involves psychophysics as well as electrophysiology.

- PhD student in the lab of Prof. Tim Griffiths. Studied auditory cognition and the mechanisms the brain uses to make sense of the acoustic world. Specifically, my work addressed how the brain segregates auditory objects from complex acoustic scenes. My research involved behavioural tests, fMRI and electrophysiology.
Figure-ground segregation, the brain’s ability to group related features into stable perceptual entities, is crucial for auditory perception in noisy environments. The neuronal mechanisms for this process are poorly understood in the auditory system. Here, we report figure-ground modulation of multi-unit activity (MUA) in the primary and non-primar...
Information from Magnetic Resonance Imaging (MRI) is useful for diagnosis and treatment management of human neurological patients. MRI monitoring might also prove useful for non-human animals involved in neuroscience research provided that MRI is available and feasible and that there are no MRI contra-indications precluding scanning. However, MRI m...
Segregating the key features of the natural world within crowded visual or sound scenes is a critical aspect of everyday perception. The neurobiological bases for auditory figure-ground segregation are poorly understood. We demonstrate that macaques perceive an acoustic figure-ground stimulus with comparable performance to humans using a neural sys...
Natural sensory scenes are often very complex, with a multitude of overlapping objects in space and time. In order to direct behaviour, a critical aspect of everyday perception is the segregation and grouping of relevant features from those scenes, known as figure-ground segregation. The neurobiological basis of auditory figure-ground processing is...
In this study, we show direct electrophysiological evidence of figure-ground segregation in primary and non-primary auditory cortex, with a systematic effect of figure saliency in the anterior, non-primary areas.
In this study, we demonstrate that macaques are, similar to humans, able to extract auditory objects from complex acoustic scenes. Moreover, we present evidence that perceptual organisation takes place in rostral parts of the auditory belt and parabelt.
