    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 develop new computational strategies to process bio- electromagnetic signals measured with fetal magnetoencephalography (fMEG), adult and pediatric magnetoencephalography (MEG) and electroencephalography (EEG). As part of fetal MEG laboratory, I collaborate with the UAMS Women’s Mental Health Program to study the maternal-fetal physiology including the effects of various clinical drugs on fetal brain activity. I am actively involved in the adult EEG/MEG community through collaborative work, developing and applying signal processing techniques to intracranial and high density EEG data. Currently, I am the scientific director of Arkansas Children’s Hospital (ACH) MEG laboratory to perform clinical MEG in pediatric epilepsy, brain tumor and translational MEG research together with epileptologists, neurosurgeons and other researchers.
