Robert Gourdie, Ph.D.
- Center Director at Heart and Reparative Medicine Research, FBRI
- Cardiovascular engineering
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 heart bioelectricity - including new ideas on how cardiac conduction may occur via an ephaptic-electric field based 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, radiation injury and cancer.
- Research on how connexins are involved in the development of drug resistance by glioblastoma, breast cancer, melanoma and other cancers.
- Development of novel orally administered drug delivery devices based on milk exosomes.
- University College London, United Kingdom: British Heart Foundation Postdoctoral Fellowship, Developmental Biology and Anatomy
- University of Canterbury, New Zealand: Ph.D. , Biophysics
- University of Auckland, New Zealand: M.S. (1st class honors)
