Paleoarchean terrestrial hot springs: The ~3.5 billion year old Dresser Formation, Pilbara, Western Australia

Tara is a PhD candidate at the Australian Centre for Astrobiology of the University of New South Wales Australia. Her research interests include astrobiology and science education. Her PhD work is focussed on the geological setting and ecology of some of Earth’s oldest evidence of life in the c. 3.5 Ga Dresser Formation in Western Australia. Tara’s work has also led to the production of an online, virtual field trip based on observations from the Pilbara. The VFT has been used in an online Astrobiology course at UNSW since 2016 to teach multidisciplinary science students about early life on Earth, geology and scientific practice.

Supervisor: Professor Martin Van Kranendonk
