Research Interests

The primary foci of my research are within several domains, including: 1) the functional organization of sensory-cognitive systems, 2) multisensory processing, and 3) the development of methodological and analytical tools for electroencephalography (EEG) in conjunction with functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS). These topics have been addressed by applying a wide breadth of state-of-the-art brain imaging and psychophysical methodologies, with a parallel objective being to facilitate transversal interpretations across species, brain imaging techniques, and populations (e.g. healthy cohorts and neuropsychological and neuropsychiatric patients).

The underlying technical approach in my group is to use EEG as a neuroimaging technique. This is predicated on the notion that spatio-temporal information is critical for a comprehensive understanding of brain function. Electromagnetic recordings have a major advantage in their high temporal resolution, which is essential for addressing when during sensory-cognitive processing during brain areas become active and in what processing step(s) each is involved. Temporal information is equally critical for addressing questions of sequential versus parallel activation, feedforward versus feedback processing, and how information is ‘bound’ into unified percepts. However, it remains debated how to use such non-invasive recordings to actually glean statistically-based, neurophysiologic interpretations of response modulations. My ongoing work in this area, in strong collaboration with the group of Prof. Christoph Michel (www.brainmapping.unige.ch) as part of our joint direction of the EEG Brain Mapping Core of the Centre d’Imagerie Biomedicale (www.cibm.ch), is directed at developing analysis techniques that benefit from the added information of high-density electrode montages. These efforts have lead to the development of an analysis software Cartool that is freely available to researchers and is now used by leading EEG laboratories world-wide.
