Doris Wagner PhD

Doris Wagner is an American biologist who is the Robert I. Williams Term Professor of Biology at the University of Pennsylvania. Her research looks to better understand the structure-function relationships of plant cells. She established the Epigenomics of Plants International Consortium. Wagner is a Fellow of the American Society of Plant Biologists. Wagner was an undergraduate student at the Technical University of Munich. She started a graduate degree at the University of California, Berkeley, where she studied the structure-function properties of phytochrome B. After earning her doctorate, Wagner joined the California Institute of Technology as a Helen Hay Whitney Foundation research fellow.

Wagner is interested in how the genomes within chromatin are altered in response to environmental signals. She has focused on ATP-dependent chromatin remodeling and shown that chromatin remodeling regulates many distinct processes. In 2010, she founded the Epigenomics of Plants International Consortium (EPIC). Wagner also investigates the fundamental mechanisms that underpin the reproductive development of Arabidopsis thaliana. This includes how the helix-turn-helix transcription factor LEAFY (LFY) directs the formation of primordium and the onset of reproduction. To investigate LFY, Wagner uses global expression and binding studies. Wagner believes that LFY gets hold of particular parts of the chromatin bundle, loosens the structure, and recruits new proteins. This eventually permits genes to be transcribed into RNA.
