Dr George Janes is a Volunteer Writer at BioNews. He obtained his PhD in the field of developmental biology, with his thesis focussing on the developmental responses of plant roots to mineral deficiency stress. He went on to postdoctoral positions at the University of Nottingham (where he studied the role of plant hormones in root growth) and at the Swiss Federal Institute of Technology in Zurich (where he studied vascular development in plant roots).
