Giovanni M. Di Liberto

Giovanni received his Master's degree in Computer Engineering from the University of Padova, Italy in 2013. After a period working at his thesis at University College Cork (UCC, Ireland), he joined Edmund Lalor’s research lab in Trinity College Dublin where he pursued a PhD in auditory neuroscience in the Department of Electronic & Electrical Engineering. Giovanni received his PhD in 2017 and he joined the Laboratoire des Systèmes Perceptifs at École Normale Superieure (Paris) immediately after, under the supervision of Alain de Cheveigné. Giovanni currently holds a postdoctoral researcher position under the supervision of Shihab Shamma.

Giovanni's scientific interests centre on understanding the brain mechanisms underlying speech comprehension. In his work, he develops data analysis methods and apply them to brain data to identify the neural processes responsible for the transformation of a sensory stimulus into its abstract meaning. Brain electrical data is measured with either non-invasive (e.g., electroencephalography – EEG) or invasive (e.g., electrocorticography – ECoG) instrumentations. A first aspect of his research is methodological and has produced novel experimental and analysis frameworks to investigate cortical auditory processing. A second aspect of his research is to use such novel methods to test theories on auditory perception, such as the hierarchical processing of speech and predictive processing theories (e.g. predictive coding). Finally, a third part of his work is translational and involves the identification of solutions to utilise my novel methods in applied settings, for example as tools to develop brain-computer interfaces (cocoha) or as objective measures for the monitoring of language development and healthy ageing.
