Mariagrazia Ranzini graduated in Psychology in 2004 and obtained a PhD in Psychology from the University of Pavia in 2010. She worked as a postdoctoral researcher at the University of Bologna, University of Padua, and Université Libre de Bruxelles (ULB). From 2020 to 2023, she was a Marie Curie Fellow (Individual Fellowship) at the University of Padua. Since 2025 she has been serving as Associate Professor at the Department of General Psychology (DPG) at the University of Padova.

Mariagrazia Ranzini’s scientific research focuses primarily on the field of cognitive psychology. Her main research area is numerical cognition, specifically investigating how attention, memory and action processes contribute to the mental representation and processing of numerical, spatial and temporal quantities. She also studies synesthesia, embodied cognition, attention deficits and calculation deficits. She conducts her research using behavioural investigation methods, such as analysing accuracy, reaction times and eye movements, as well as the effects of prismatic adaptation and optokinetic stimulation, and hand kinematics. She also employs neuroimaging techniques (EEG, MEG, fNIRS): in particular, she has recently initiated a series of studies on the neural correlates common to quantity processing and manual actions (e.g. pointing, grasping objects) using functional near-infrared spectroscopy (fNIRS).
