Our research focusses on-
1. Elucidating pathophysiological mechanisms of neurological disorders focusing on ion channels.
2. Creating novel brain models using human induced pluripotent stem cells (hiPSCs) from patients
to study neurological disorders.
3. Translating novel mechanisms to develop therapy against neurological diseases.
