Kate Trinajstic is a vertebrate palaeontologist. She received a Bachelor of Sciences (Hons) from Murdoch University and a Ph.D. from the University of Western Australia (UWA). She then continued at UWA as a postdoctoral research assistant, examining the biostratigraphic utility of microvertebrates. Kate was appointed as senior Curtin Research fellowship at Curtin University in 2008 looking at mechanisms of extinction and faunal changes at the end Devonian. Her current research includes the evolutions of reproductive structures and strategies, as well as ontogenetic change and skeletal differentiation. Kate’s currently holds of professorship at Curtin University.
