Blossom received a B.S. in Natural Sciences (1992). She earned her PhD (1999) from the University of Arkansas for Medical Sciences. She completed a 3 year postdoctoral fellowship in Immunotoxicology at Arkansas Children's Hospital Research Institute in 2003.

Personal Statement

My research is focused on studying impacts of environmental toxicants on autoimmunity and hypersensitivity disorders in animal models. I am a basic scientist/immunologist/T cell biologist by training with specific expertise in immunotoxicology of water contaminants, namely the industrial solvent, trichloroethylene. I have been continuously funded as a PI since 2010. In my new R01 we will investigate the epigenetic impacts of TCE exposure in pathogenic subsets of CD4+ cells and study how they promote autoimmune disease.
