Ronny Bujok is a Postdoctoral Researcher at the Donders Center for Cognition [DCC], part of the Donders Institute at Radboud University, Nijmegen, The Netherlands. He is a member of the Speech Perception in Audiovisual Communication [SPEAC] research group, funded by the ERC Starting Grant ‘HearingHands’ [101040276; PI: Hans Rutger Bosker] that started in September 2022. He performed his PhD research at the Max Planck Institute for Psycholinguistics, investigating how simple up-and-down hand gestures (‘beat gestures’) influence low-level speech perception. After his PhD, he took up a postdoc position with Dr. Lieke van Maastricht at the Centre for Language Studies, Radboud University, Nijmegen. After that, he started his current postdoc with the SPEAC group. Present research lines focus on individual differences in gesture-speech synchrony in production and perception.
