Research Interests

I’m currently focused on studying the interbrain synchronization that takes place during speech production and speech perception by using EEG. Understanding how and when the rhythms of brainwaves of different people match each other is a key factor in understanding language and social interactions in general.

Brain-to-brain entrainment, brain-to-speech entrainment, interbrain synchronization, language, neuroimaging (EEG, hyperscanning, TEs, MRI), interpersonal communication.
