Areas of interest: His current research interests are functional neuroimaging, specifically functional Magnetic resonance Imaging (fMRI), Magnetoencephalography (MEG) and electroencephalography (EEG). The aim is to apply those techniques to evaluate the neuronal modulation promoted by different drugs and to investigate stroke survivors.

The Functional Neuroimaging Lab (NeuroImago) was established in 2003 and is focused on the application of non-invasive tools to investigate questions related to the field of cognitive and clinical neurosciences. For now, we have devoted special interest to Functional Magnetic Resonance Imaging (fMRI), electroencephalography (EEG) and magnetoencephalography (MEG).

Currently, the lab is installed in Hospital Universitário Onofre Lopes (HUOL) of the Federal University of Rio Grande do Norte (UFRN) and Brain Institute.
