Research Interests

  • Bioelectric control of cell behaviour and positional identity during regeneration
  • Role of neural-supplied physical guidance cues in regeneration
  • Reprogramming of cell identity by neural-based environmental cues
  • Common molecular pathways regulating regeneration and cancer

Upon injury, there are three ways that a tissue can respond: 1) scarring, 2) regeneration, or 3) neoplasia. In mammals, the default response is scarring. Many cell-intrinsic and environmental factors play a role in the response to injury, but induction of complete regeneration in mammals remains elusive. Understanding the key regulatory signals in the cellular response to injury can give insight into promoting regeneration. The overarching goal of our lab is to identify the environmental cues that drive cell behaviour following wounding and to understand how cells sense and respond to these cues to promote regeneration.

It is well established that innervation is essential for regeneration in both non-mammalian and mammalian species. Nerves are one of the first structures to infiltrate into an injured tissue and their ablation inhibits regeneration, resulting in aberrant tissue patterning. While nerves have been recognized as a potential means to promote regeneration, the exact mechanisms remain largely unknown. By identifying the core neural-mediated drivers of regeneration, we can target their deficiency in mammals to develop new regenerative medicine strategies
