Dr. Ribeiro-da-Silva received his MD and PhD in Porto, Portugal. His main research interest is the unravelling of the mechanisms underlying persistent pain, both in the central and peripheral nervous systems. He is particularly interested in animal models of arthritis pain and of neuropathic pain. Methods used in his lab include: immunocytochemistry at the light and electron microscopic levels, animal behaviour testing, and neurochemistry. He uses advanced tools such as replication deficient viral vectors and transgenic models to study synaptic circuits in the spinal cord and their changes in pain states. He is a core member of the Alan Edwards Centre for Research on Pain and an investigator of the Quebec Pain Research Network (QPRN).
