Research Interests
Our lab is interested in understanding the organization and the functioning of the spinal cord, and the neural networks that drive and modulate this integral part of the nervous system. The spinal cord not only gates sensory input and controls motor output, it also governs a wide range of involuntary functions in the body, such as blood pressure control, heart rate, and it is involved in a number of neurological disorders, such as Restless Legs Syndrome, or RLS.

Using electrophysiological and pharmacological approaches as well as gene expression analyses, research in the lab is focused on the deciphering the dynamic actions of the neurotansmitter Dopamine in the spinal cord, to better understand how the actions of the this neuromodulator can dynamically adapt the performances of an organism.
