Selected publications

Modulating speech tracking through brain state-dependent changes in audio loudness. Journal of Neural Engineering (2026).

This study suggests that neural speech encoding is governed more by internal attentional state than by external stimulus salience, providing proof-of-concept evidence for brain state-dependent stimulation as a principled approach to adaptive speech enhancement.

Speaking and listening to inter-brain relationships. Cortex (2023).

This viewpoint article offers insights to improve the conceptual clarity and empirical standards of inter-personal interaction studies using hyperscanning.

Differential brain-to-brain entrainment while speaking and listening in native and foreign languages. Cortex (2019).

This study was the first to report differences in brain-to-brain synchronisation for verbal communication in native and foreign languages.

Brain-to-brain entrainment: EEG interbrain synchronization while speaking and listening. Scientific Reports (2017).

This study was one of the first to demonstrate inter-brain coupling during speaking and listening using EEG hyperscanning.
