Research

Welcome to our lab! We currently have two research directions: (1) channelopathy, (2) signaling mechanisms underlying the neuroinflammation. By understanding the pathophysiological mechanisms of ion channel diseases and the impact of neuroinflammation, we may develop ways to prevent and treat these diseases in the future.

Research Area

  1. Molecular assembly and gene regulation of ion channels.
  2. Biosynthesis and trafficking of ion channels.
  3. Pathophysiology of ion channel diseases.
  4. Neuroinflammation.
