Understanding the evolution of Earth and life over the last 4.5 billion years is both a fascinating topic and essential knowledge. Scientists in the Department of Earth Sciences undertake world-class research in geology, geochemistry, geophysics, geobiology/palaeobiology, planetary science and current issues such as global change. This provides our postgraduate students with a wealth of knowledge and experience to draw from, so that they can build a solid foundation for their future careers in science. Our postgraduate students, like our staff scientists, also visit important field sites worldwide and perform experiments using cutting-edge instrumentation. Our postgraduate programs aim to produce well-rounded Earth scientists, with a global perspective by encouraging creative and critical thinking, and developing their capability for making original discoveries.
