Pr. Christophe Grova is directing The Multimodal Functional Imaging Laboratory, a multidisciplinary team composed of neurologists and methodologists, investigating multimodal data fusion to characterize brain mechanisms in healthy conditions and also during epileptic activity.
Being affiliated to both Biomedical Engineering and Neurology and Neurosurgery Departments at McGill University since July 2008, Dr. Grova investigates the integration of multimodal functional data to study brain mechanisms at the time of epileptic activity. His research project aims at combining multimodal data in order to detect additional information that could be missed by considering each modality individually. His project involves the integration of three promising functional modalities:
The comparison of EEG/fMRI and EEG/NIRS offers a unique way to address in vivo the question of the integrity of the neurovascular coupling in the epileptic brain. In addition of studying brain mechanisms at the time of epileptic discharges, Dr. Grova is currently applying similar methodologies to study resting state functional connectivity in epilepsy patients.
In July 2014, Christophe Grova became an assistant Professor in the Physics Department and a researcher in the brand new multimodal imaging platform of the PERFORM centre at Concordia University, while remaining an adjunct Professor in Biomedical Engineering Department and Neurology and Neurosurgery Department of McGill University. This new imaging platform of PERFORM is equipped with a 3T MRI, simultaneous SPECT/CT and PET/CT devices, TMS and high density MR compatible EEG. His research projects are about to evolve to incorporate these new modalities, in order to study epileptic activity, but also many other applications in neurosciences including healthy aging, exercise and multimodal analysis of resting state functional connectivity.
