Kirk McKenzie is a Professor in the Centre for Gravitational Astrophysics at the Research School of Physics and Research School of Astronomy and Astrophysics, and he holds the SmartSat CRC Professorial Chair for Precision Measurement in Space. Kirk and his team are developing lasers for precise measurements that will map Earth’s water to measure climate change effects, ice-cap melt, and monitoring of water basins such as the Murray-Darling. Kirk leads one of the Moon to Mars missions to develop laser measurement technology for the next Gravity Recovery and Climate Experiment (GRACE) Mission, in partnership with CEA Technologies.
