A/Prof Dagmar Wilhelm is a vertebrate developmental biologist with a background in molecular biology and cancer research. Using mouse as a model system, the ultimate goal of her research is to understand the genetics of sex determination and gonad development, and how failure results in human disorders of sex development and infertility. Dagmar received her PhD in Cancer Biology (Heidelberg, Germany) and completed her postdoctoral training with Prof Christoph Englert at the Research Centre Karlsruhe, Germany and Prof Peter Koopman at the Institute for Molecular Bioscience (IMB), Brisbane. She started her own lab after receiving an NHMRC CDA level II, followed by an ARC Future Fellowship. In 2016 she took on a T&R position at the University of Melbourne. Dagmar has has made seminal contributions to the field including the identification of the first in vivo targets of WT1, the elucidation of a back-up mechanism to ensure testis differentiation, the role of miRNAs in testis differentiation, and, more recently, ovarian development and function.
