    Collapse research overview
    I have been directly involved of multidisciplinary groups to develop expertise in the area of biomedical signal processing to apply new techniques for electrophysiological signals from large array of sensors. I have a strong background in advanced neuroimaging methods to process brain signals measured with non-invasive techniques such as fetal magnetoencephalography (fMEG), adult and pediatric magnetoencephalography (MEG) and electroencephalography (EEG).I had the opportunity of acquiring advance technical understanding of MEG/MRI, EEG and fMEG technologies through training internships at the Dynamic Neuroimaging Laboratory at the McGill University (Montreal, Canada) and the SARA/Fetal MEG Research Center in the University of Arkansas for Medical Sciences (UAMS, USA). Both universities have major research and core facilities for adult and fetal brain research imaging with prominent expertise in biomedical signal processing analysis.

    Currently, I am the Scientific Director of Arkansas Children’s Hospital (ACH) MEG laboratory to perform clinical MEG in pediatric epilepsy. Additionally, I perform translational MEG research together with epileptologists, neurosurgeons and other researchers. I still maintaining strong collaborative ties today at UAMS fMEG laboratory to study the maternal-fetal physiology. I expand my collaborations with the UAMS Women’s Mental Health Program to study the effects of clinical drugs on fetal brain activity. I am actively involved in the adult EEG community through collaborative work, developing and applying signal processing techniques to intracranial and high density EEG data in epilepsy and Parkinson’s disease. My research interests are to expand the clinical applications of neuroimaging MEG technology to study cognitive brain development and function across the lifespan and apply novel computational strategies to process bio-electromagnetic signals.
