Research Areas

  • Cardiovascular engineering

Research Interests

The research of the Gourdie Laboratory is on the subunit proteins of gap junctions, which are called connexins. Connexins are the channels that enable direct communication between cells. Projects in the laboratory include:

  • Research on connexins in cardiac electrical excitation spread – including new ideas on how conduction of electrical impulses in the heart occurs via an ephaptic mechanism.
  • Studies of how connexin hemichannels are involved in determining injury severity following heart attack, stroke and traumatic brain injury.
  • Drug discovery – development and testing of new compounds targeting connexin channels for use in diseases of the heart and brain, wound healing, and cancer.
  • Research on how connexins are involved in the development of drug resistance by glioblastoma brain cancer patients being by treated anti-cancer drugs.
  • Studies on preventing excessive scarring in breast cancer survivors undergoing breast reconstruction following mastectomy.
