Louis-Eric Trudeau, PhD, is a neuroscientist focusing on the connectivity and vulnerability of dopamine neurons and other neurons perturbed in Parkinson’s disease. After graduate training at the Université de Paris and Université de Montréal, he completed postdoctoral training at Iowa State University and was recruited to the Université de Montréal in 1997. His lab is well known for its uses a range of in vitro and ex vivo assays in the study of dopamine neuron function, including their neurochemical identity, connectivity and vulnerability, with a present focus on the implication of mitochondrial dysfunction and immune mechanisms in Parkinson’s disease.
