Dr. Newton is a lecturer in the Physics & Astronomy department of the University of Southampton. He is interested in understanding phenomena in correlated electronic materials such as vanadium dioxide and zinc oxide. His research is focused on coherent X-ray diffraction imaging (CXDI) of nanoscale materials using hard X-ray synchrotron sources such as the SACLA X-ray free electron laser (XFEL) facility and the Diamond Light Source. He is also at the forefront in the study of self-assembled nanoscale materials and devices. These include group II-VI semiconductor materials such as zinc oxide (ZnO). Dr. Newton also conducts theoretical research into non-linear optimisation and the phase retrieval problem which is encountered in a number of disciplines including X-ray crystallography, sparse-aperture imagery and astronomy. He is also the author of the "Interactive Phase Retrieval Suite", the first software package that allows for real-time visualisation of the reconstruction of phase information in both two and three dimensions. This is used for analysing diffraction data obtained from coherent X-ray diffraction imaging experiments. |
