About Dr. Mandel
Dr. Mandel joined the department in 2014. She received a B.A. from Carson Newman University with a focus in organismal biology, ecology, and natural history. Her Ph.D work involved plant conservation and evolutionary genetics both in rare, endangered species as well as weedy, invasive. Following this, her post-doctoral research at The University of Georgia was aimed at identifying the genetic basis of evolutionary and agronomically important traits in cultivated sunflower. Her research at the UofM includes plant population and quantitative genetics, evolutionary genetics, and phylogenetics. She employs field, laboratory, and greenhouse approaches to gain an understanding of the processes and mechanisms that lead to the genetic, phenotypic, and ecological diversity we see in the world. Courses taught include Ecological Genetics 7795/8705, Plant Ecology 4053/6053, and General Biology 1110.
