Doctor Kate Umbers

Senior Lecturer Zoology,


Kate grew up in western Sydney and completed her PhD at Macquarie University in 2011 under the supervision of Prof Marie E Herberstein. She then moved to Canberra for a year to take up a Postdoctoral position at The Australian National University with Prof J. Scott Keogh and Prof Hanna Kokko. In 2013, Kate was awarded a Vice Chancellor's Postdoctoral Fellowship at the University of Wollongong hosted by Dr Phillip G Byrne and spent much of this time concurrently working at the University of Western Australia with Prof Leigh Simmons. Since 2015 Kate has been a Lecturer in Zoology at UWS, Hawkesbury.

Kate's research focuses on a variety of topics, usually (but not always) related to understanding the mechanisms, functions and evolution of biological colouration. In addition to her fascination with animal colouraiton she loves investigating research questions on animal behaviour, genetics, thermoregulation and mating systems. Kate can often be found around Kosciuszko among the snow gums chasing colourful insects and frogs, tromping through mud on rainy nights looking for toxic frogs, or with her head in the ocean searching for nudibranchs.
