Dr Marlton is a materials scientist who is primarily interested in understanding structure-property relationships in functional materials. His main focus is determining the atomic-scale features in ferroelectric materials that improve their performance in solid-state cooling.

Dr Marlton obtained his BEngn and BSci from the Australian National University in 2013. He completed his PhD at the University of New South Wales with Associate Professor John Daniels, focusing on using combinatorial methods and high energy X-ray diffraction to explore lead-free ferroelectrics. He has worked as a postdoctoral researcher at Aarhus University in Denmark and the University of Sydney, where he became highly experienced in using total scattering to understand disorder and local structures in functional materials.

Dr Marlton regularly conducts neutron and X-ray experiments at large-scale facilities, such as the Australian Synchrotron, the Australian Centre for Neutron Scattering, Oak Ridge National Lab, Diamond Light Source or European Synchrotron and Radiation Facility.
