I hold a bachelor degree in Communication Science, a master’s degree in Life Science and Technology and a PhD in Neuroscience from the Federal Institute of Technology in Lausanne (EPFL, Switzerland). During my thesis, conducted at the Laboratory of Cognitive Neuroscience, led by Prof. Olaf Blanke, I studied the functional mechanisms of specific aspects of bodily self-consciousness; the sensation that the body we occupy belongs to us (body ownership), that we are located somewhere in space (self-location) and that we are directed at the world (first-person perspective). Furthermore, I was interested in whether and how these “high-level” aspects compare to behavioral and neural mechanisms of “low-level” multisensory integration specifically within the peripersonal space. To this aim, I employed multisensory bodily illusions inspired from experimental psychology coupled with psychophysics, electric vestibular stimulation, functional magnetic resonance imaging (3T and 7T), virtual reality and MR-compatible robotics.

I have joined the MySpace lab in March 2018 where I currently act as the lab manager and coordinate, in parallel, the Neuroscape@NeuroTech research platform for clinical neuroscience at the University Hospital of Lausanne (CHUV). I am currently involved in several research projects whose aims are (1) assessing the immunological behavioral and biological responses triggered by exposure to pathogen-carrying faces in virtual reality, (2) assessing the potential of using adaptive physical and cognitive training in immersive video games for cognitive rehabilitation in patients with multiple sclerosis and (3) validating a novel tablet-based cognitive assessment tool against gold-standard neuropsychological examinations for quantifying memory impairments.
