Professor Stuart Gregson has thirty years of experience working in the space, aerospace and communications sectors and is Director of Operations and Research at Next Phase Measurements, and an honorary visiting professor in the School of Electronic Engineering and Computer Science at Queen Mary University of London. He received his BSc degree in Physics, his MSc degree in Microwave Solid State Physics, both from the University of Portsmouth and his PhD degree from Queen Mary University of London. From his time with: Airbus, Leonardo, NSI-MI, NPL, and Next Phase Measurements; Prof. Gregson has developed special experience with near-field antenna measurements, finite array mutual coupling, computational electromagnetics, installed antenna and radome performance prediction, compact antenna test range design & simulation, electromagnetic scattering, 5G OTA measurements and has published more than a hundred peer-reviewed research papers on these topics, regularly contributing to and organizing industrial courses in these subject areas. At the end of 2007 he was the lead author of the research text, Principles of Planar Near-Field Antenna Measurements, and in 2014 he co-authored a second text, Theory and Practice of Modern Antenna Range Measurements, both of which are in their second editions and are published by the IET within their Electromagnetic Waves Series. He has twice received the AMTA Best Technical Paper award.  In 2015 he jointly presented the AMTA Sunday Short Course on Near-Field Measurement Error Analysis & Computational Electromagnetic Modelling and currently organizes and presents the IET’s annual short course on Modern Antenna Range Measurements. In 2018, Prof. Gregson was elected to the AMTA Board of Directors where he served first as Treasurer, then as Vice President and until 2025 as Chair of the AMTA Growth Committee.  In 2022 he received the AMTA Outstanding Service Award.  He is a Fellow of the Antenna Measurement Techniques Association, a Fellow of the Institution of Engineering and Technology, a Fellow of the Institute of Physics, and is a chartered Engineer and Physicist.
