Ricardo-Bruña

I have an MsC. on IT engineering by Universidad de Valladolid and a PhD. on biomedical engineering by the Technical University of Madrid. I work on the Laboratory for Cognitive and Computational Neuroscience since 2011, and my focus is on the development of methods to clean and analyze electrophysiological signals as measured by EEG and MEG.

In these years I have worked both on methods development and on its application to aging, tremor and alcohol consumption. I have also worked on the development of HERMES, a toolbox for the calculation of functional and effective connectivity.
