Assistant Professor at the Bioengineering Dept. of Instituto Superior Tecnico (IST)/University of Lisbon, and Researcher at the Institute for Systems and Robotics (ISR/LaSEEB). My main research area involves the use of EEG-based Brain-Computer Interfaces (BCI) with interactive systems for neurorehabilitation. Specifically, the study of cortical potentials that may be used to convey information about the user's brain activity to a computer system (e.g. user-interfaces, virtual environments, or robotic devices) and to develop methods that will allow improving the quality-of-life in assistive or restorative ways. Overall, my research is in the intersection between the fields of computer and biomedical engineering with a two-fold objective: On the one hand, to design robust brain-computer interaction for communication and control, while on the other hand, to identify the underlying mechanisms of brain recovery after stroke or other cerebrovascular and neurological disorders.
