The central goal of my research has been to characterize cannabinoid signaling in the brain and the eye. Cannabinoids have been with us for thousands of years but only recently have we begun to learn how they work in the body. Cannabinoid CB1 receptors are nearly ubiquitous in the CNS and are involved in many important functions including (un-)learning and memory, pain, and motor control. The cannabinoid signaling system includes several receptors, endocannabinoids, enzymes that produce and break them down. In neuronal studies my primary approach is to use electrophysiology in combination with molecular biology and anatomy to investigate specific mechanisms of cannabinoid signaling. I have also gradually returned to the subject of my graduate work—cannabinoid signaling in the eye—where we have several projects relating to glaucoma, cell migration, and retinal function.
