Joel Meyer is principal investigator on a new five-year grant from the National Institute of Environmental Health Sciences (NIEHS) that will provide nearly $2 million to support research aimed at identifying which mechanisms of pollutant-induced mitochondrial dysfunction cause dopaminergic neurodegeneration. Dr. Meyer hopes to narrow the field of candidate chemicals that might be linked with Parkinson’s by defining which mechanisms of mitochondrial toxicity cause dopaminergic neurodegeneration.
