Research Description

The research in our laboratory is primarily dedicated to a better understanding of neuroinflammatory processes following brain insults such as prolonged seizures. We have also recently begun to explore the neuron-glia interactions in malignant gliomas, the most devastating brain tumors that constitute a major cause for epilepsy, particularly in the elderly. We attempt to unlock the cellular and molecular mechanisms whereby normal brains are transformed to generate spontaneous recurrent seizures, i.e., acquired epileptogenesis. We are also interested in developing novel antiepileptic and/or antiepileptogenic therapeutics in close collaboration with medicinal chemistry laboratories. To achieve these goals, we use a variety of technologies and experimental systems, such as high-throughput screening, chemical genetics, TR-FRET, RNAi, CRISPR/Cas9, microdialysis, time-locked video EEG, behavioral tests, etc.
