Julien Dirani

Julien Dirani is a Distinguished Postdoctoral Fellow at Carnegie Mellon University's Neuroscience Institute, with additional affiliations at the University of Pittsburgh Medical Center. His research investigates the neural mechanisms of semantic cognition using multimodal neuroimaging and computational methods.

Dirani's work examines how conceptual knowledge is represented across brain regions during language tasks, with emphasis on cross-modal processing and lexical-semantic interfaces. Recent MEG studies explore temporal dynamics of conceptual representations, dissociating visual and lexical features. His publications span neuroimaging techniques (MEG/fMRI), cognitive models of language, and cross-linguistic validation of psychological instruments.

Collaborations include developing benchmarks for AI reasoning and investigating syntax processing in Arabic. Research integrates cognitive neuroscience with computational modeling to understand semantic memory organization.
