Professor Ken Baldwin is a laser physicist based at the Australian National University, where he is Director of the ANU Energy Change Institute, and Deputy-Director of the Research School of Physics and Engineering.

Professor Baldwin is a Fellow of the Australian Institute of Physics, The Institue of Physics (UK), the Optical Society of America and the American Physical Society. He is a past-President of the Australian Optical Society, and is the first Australian to be elected to the Board of Directors of the Optical Society of America. In 2007, Professor Baldwin was awarded the W.H. Beattie Steel Medal, the highest honour of the Australian Optical Society, and in 2010 he was awarded the Barry Inglis Medal by the National Measurement Institute for excellence in precision measurement.

Professor Baldwin is also a past-President of the Federation of Australian Scientific and Technological Societies (FASTS). In 2004 he won the Australian Government Eureka Prize for Promoting Understanding of Science, for his role in initiating and championing "Science meets Parliament".

### Research interests

Professor Baldwin's research interests lie in developing new laser technologies for precision measurement to test quantum theories of atomic and molecular structure that can be used, for example, to determine how air molecules react to ultraviolet light, thereby enabling better understanding of energy balance and ozone formation in the earth's atmosphere. He is also a pioneer in atom optics - a field which uses lasers to create new technologies for atoms which are the analogue of optical elements for light - that can be used e.g. to create nanostructures for better microchips. Lasers can also be used to cool atoms to the lowest temperatures in the universe, at which point they behave more like waves than particles, enabling them to be used as sensitive detectors e.g. of changes in the earths gravitational field for mineral exploration.

Professor Baldwin is also the Director of the ANU Energy Change Institute (www.energy.anu.edu.au). A key to many challenges facing the world today is a world-wide change to carbon-free forms of energy production. The ECI provides authoritative leadership in Energy Change research through a broad portfolio ranging from future energy technologies, to energy efficiency, regulation, economics, sociology and policy. The ECI comprises more than 300 staff and PhD students and around $100 million in infrastructure and facilities, supported by a major portfolio of external grant funding. ### Groups • Do, Thang N., Burke, Paul J., Baldwin, Kenneth G.H., and Nguyen, Chinh T. 2020.
