Dr Daniel S. Hussey
Dr. Hussey is a research scientist at the National Institute of Standards and Technology, where he leads a team in the development of novel neutron imaging and optics techniques for materials science applications. To enable the visualisation of the water content in the catalyst layers of operating hydrogen fuel cells, Dr Hussey works to improve the achievable spatial resolution of neutron imaging. This includes the development of new detectors, such as micro-channel plates, and wholly new neutron imaging methods, notably a neutron analog to Hooke’s microscope using Wolter optic mirrors.
One of the most exciting new research projects in the field is under development by Dr Hussey and other participants in the INFER collaboration. Together they are building a far field grating neutron interferometer that will provide multi-scale images, spanning length scales from the femtometer to the decimeter. Dr Hussey is also engaged in developing quantitative image analysis routines, for instance, data fusion algorithms that permit researchers in the fields of batteries, concrete, and geosciences to take fully advantage of the NIST-NeXT data sets.Dr Hussey holds one U.S. and one world patent in the area of signal processing, has co-authored over 180 peer-reviewed journal articles and book chapters, has been a co-PI on three funded NIST Innovations in Measurement Science projects, is a fellow of the American Physical Society, and has received several awards including the Presidential Early Career Award for Scientist and Engineers, the Arthur S. Flemming Award, an R&D 100 award, and the Department of Commerce Silver Award.
