I am Wellcome Trust Biomedical Research Fellow Since 2011. This is a 5-year scheme for young researchers to establish their own lines of research. After four years of postdoctoral studies, one in Paris and three here at the CBU I am now an Independent Researcher mainly linked to the Executive Processes Group.

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 new 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.

A full CV, publications and miscellanea are here. In the page of the Consciousness and Cognition Lab.
