His early research focused on the modulation of
glutamate receptor-mediated
synaptic transmission. During this period he and his team discovered that
glycine is a coagonist rather than modulator of
NMDA receptors, that shrinkage of extracellular space mediates the transition between interictal and ictal states in the high potassium model of seizures, that a single amino acid residue controls calcium permeation in glutamate receptor channels, and that
ifenprodil analogs inhibit NMDA receptors by increasing the sensitivity of receptors to proton inhibition. His current research focuses on the myriad roles of
neuroinflammation in neurologic disorders. He demonstrated a profound role for
EP2 receptor activation by prostaglandin E2 in
COX-2 related pathologies. His work highlights the importance of neuroinflammation in epilepsy. == Awards and honors ==
