Joel Meyer


Professor of Environmental Genomics in the Division of Environmental Sciences and Policy

Dr. Meyer studies the effects of toxic agents and stressors on human and wildlife health. He is particularly interested in understanding the mechanisms by which environmental agents cause DNA damage, the molecular processes that organisms employ to protect prevent and repair DNA damage, and genetic differences that may lead to increased or decreased sensitivity to DNA damage. Mitochondrial DNA damage and repair, as well as mitochondrial function in general, are a particular focus. He studies these effects in the nematode Caenorhabditis elegans, in cell culture, and collaboratively in other laboratory model organisms as well as in human populations in the USA and globally.
