Mateusz has completed his MA degree in Applied Psychology and PhD in Psychology at Jagiellonian University in Cracow where he was investigating neurocognitive mechanisms underlying identification with a virtual body (avatar) as an example of plasticity of one's self-representation. During studies he extensively worked with the SOMBY Lab at Radboud University in Nijmegen and at Central European University in Budapest. After completing his PhD he worked as a Post Doc at Monash University in Melbourne in the Cognition & Philosophy Lab investigating self and consciousness within the framework of predictive coding/Bayesian brain. In 2019 he rejoined the SOMBY Lab. His current work involves behavioral and neuroimaging research on bodily self-representations, self and other in joint action, as well as coordination and communication.
