We study physical properties and mechano-electrical-chemical signalling in cancer. While extensive research has informed genetics and biochemical mechanisms in tumorigenesis, how mechanical and electrical signalling regulate cancer is less defined. Ion channels govern cell behaviours by perceiving physicochemical cues (mechanical force, membrane voltage, temperature, pH etc.) to control ion flux across membranes. We ask the following questions:

  • At the systemic level, what are the mutational landscape and functional alterations of ion channels in cancer?
  • At the tissue level, how do ion channels regulate tumour initiation, progression, metastasis, and drug resistance in genetically tractable animal models?
  • At the cellular level, how do ion channels perceive physicochemical cues to control cancer cell state?
  • At the molecular level, how do different ion channels form a functional network to regulate cancer cell behaviours?
  • Can we use ion channel-targeting drugs to treat cancer?

Using multi-disciplinary approaches in bioinformatics, Drosophila and mouse genetics, xenograft modelling, advanced imaging, electrophysiology, and bioengineering, we discover disease mechanisms and therapeutic vulnerabilities at the interface of cancer biology, neuroscience, and mechanobiology.
