Basic research in the Kumar laboratory is focused on synaptic physiology underlying neocortical function and plasticity. We are particularly interested in understanding the workings and role of glutamatergic AMPA and N-methyl-D-aspartate receptors in these processes.

Translational research efforts of the lab are focused on deciphering basic pathophysiological mechanisms underlying Temporal Lobe Epilepsy, the most common type of epilepsy in adults. Here, we seek to identify/isolate ictogenic cells and circuits within the parahippocampal region for the purposes of developing therapeutic/interventional strategies to combat TLE.

We use a variety of tools and techniques with electrophysiology being the mainstay of our research. We are innovators- click here to see our latest inventions.
