I grew up in France and received my Ph.D. in Neurosciences from the Claude Bernard Lyon I University. I studied the role of the medio-posterior cerebellum in gaze orientation (eye and head coordination) in  monkeys. After, several postdoctoral positions at the University of Rochester, Rochester, NY; at the UMMC, Jackson, MS and at the Institut de Neurosciences de la Timone, Marseille, France where I continued to study the oculomotor system in non-human primate, I came to UAB in the laboratory of Dr. Paul Gamlin in the Department of Ophthalmology and Visual Sciences to focus my research on vision and how the brain computes eye movements to orient gaze in 3D-space.

To orient our gaze in space and consequently, the foveae of our eyes, we perform a variety of eye movements as a function of where the object of interest is located in the visual field. Thus, my research is motivated by the understanding of the neural circuitries involved in the control of gaze movements in the 3D-space both to increase our understanding of the oculomotor system, and to work towards treatments for ocular disorders.

Teaching/research interests:

Dr. Quinet current research focus is the study of the oculomotor system and more specifically, the neuronal network involved in coordinated eye movements in three-dimensional space. For this purpose, by using different neurophysiological techniques such as single unit recording, electrical micro stimulation, and pharmacological injection, she will study brain areas which are interconnected while the awake non-human primate is orienting its gaze in space. The clinical relevance of Quinet’s research is to understand the physiological basis of disorders like strabismus, which can lead to amblyopia and a substantial vision loss in one eye.
