Development of germ cells, environmental epigenetics, and transgenerational inheritance of phenotypes.
Research descriptionDeveloping germ cells are susceptible to environmental stress and consequences of exposure are both short-term and long-term. Short-term effects are limited to reproductive failure in the generation of exposed organism, whereas long-term effects are passed onto offspring across several generations in the form of both reproductive and non-reproductive diseases. Our laboratory studies epigenetic and gene expression changes associated with environmentally induced transgenerational reproductive diseases using fish and mice as experimental subjects.
