Topic: tomography in biology Stuart received his MSc in materials science and engineering at Northwestern University and his PhD in metallurgical engineering at University of Illinois. He was on the materials science faculty at Georgia Tech for 16 years where he became a professor. He then returned to Northwestern Uni as a research professor in the medical school. He has used X-ray diffraction for material characterisation for nearly 40 years and revised Cullity's classic text: Elements of X-ray diffraction. He has employed X-ray imaging for the same length of time, travelling to the Advanced Photon Source for synchrotron radiation 6 or more times per year for the past 35 years. He has published results of microCT studies of inorganic materials and composites and of mineralised tissues in mammals and echinoderms for the 30 years. He has over 240 publications, was the conference chair of the SPIE conference "Developments in X-ray tomography" from 2005 until 2015, and has written the book: "MicroComputed Tomography: Methodology and Applications"
