Researcher profile

Tomas Ros

My career has been focused on applications of real-time EEG signal processing, and how BCI and neurofeedback may be used to modulate the brain and behavior. My interdisciplinary background in physics, neuroscience and psychology has driven my interest for combining multiple modalities with human EEG recordings (e.g. EEG-TMS, EEG-fMRI, EEG-PET). During my PhD, I used transcranial magnetic stimulation (TMS) to probe for the effects of neurofeedback, showing for the first time neuroplastic changes in cortical excitability directly after a training session (Ros et al, 2010). During my postdoc at Western University in Canada, I developed a neurofeedback protocol for reducing mind-wandering, which in parallel modulated functional connectivity in fMRI salience/default-mode networks (Ros et al 2013). This led to the first translational study investigating the impact of this protocol on patients with post-traumatic stress disorder (PTSD), revealing a positive effect on their symptoms and large-scale brain networks (Ros et al, 2014, 2017). During my postdoc at the University of Geneva, I worked on several EEG projects for the rehabilitation of visuospatial attention in stroke patients (Ros et al, 2017), demonstrating network disruptions of EEG source connectivity (Ros et al, 2022). Following this, I led and contributed research to the NCCR-Synapsy program showing that alpha-rhythm neurofeedback can enhance executive functions in ADHD (Deiber et al, 2020, 2021). I have also collaborated with the UNIGE Functional Brain Mapping Lab in the advancement of spectral methods of EEG microstate analysis (Ferat et 2022) and clinical applications of machine learning (Terpou et al 2022). I am currently principal investigator and senior lecturer at the Department of Clinical Neuroscience and the CIBM Center for Biomedical Imaging at the University of Geneva.
