Xi Huang

Dr. Xi Huang’s lab decodes ion channel functions in brain cancer. While extensive research has informed genetics and biochemical mechanisms in tumorigenesis, how bioelectrical and biophysical signaling regulates cancer is less defined. Ion channels regulate cellular bioelectrical and biophysical properties by perceiving stimulations (mechanical force, membrane voltage, temperature, pH etc.) to control ion flux across membranes.

Using multi-disciplinary approaches in bioinformatics, Drosophila and mouse genetics, xenograft modeling, cell biology, advanced imaging, and electrophysiology, the Huang lab discovers ion channels as regulators of brain tumors and develops ion channel-targeting therapeutic strategies.
