Research Interests

I am interested in non-classic approaches to study the physiology and cognition of consciousness.

I have wide Interests in Cognition and neurophysiology. In the last few years I have been mainly concentrating in describing different states of consciousness such as awake, sleep, sedation, vegetative state. My latest line of work is primarily looking at how we lose consciousness and how we get it back.

I am mainly attacking the limits of cognition in the process of falling asleep or getting sedated (losing consciousness) with a combination of behavioural measures, brain markers of cognitive processes and brain markers of the micro-conscious state. Together with my students and collaborators, we use behaviour measures, electromyography, electroencephalography, functional MRI, intracranial electrodes and transcranial magnetic stimulation, to respond the main questions at the intersection between awareness and wakefulness.
