Stewart Agar is a Postdoctoral Research Assistant (PDRA) in the Geotechnics section of the Department of Civil and Environmental Engineering at Imperial College London

Stewart's research is focused on Remote Sensing and analysis of Interferometric Synthetic Aperture Radar (InSAR) in particular. His principle work from April 2023 concerns development a highly automated system for InSAR monitoring of nuclear decommissioning assets, in collaboration with EDF Energy.

Stewart has applied InSAR technology in industry, including a project monitoring ground conditions for high-speed rail and projects concerning mine stability analysis.

Stewart worked as part of the Secretariat for the Committee on Radioactive Waste Management, between 2017 and 2018. In 2017 Stewart recieved a MRes in Nuclear Energy from Imperial College London. Before this, he graduated from Lancaster University in 2014 with a MEng in nuclear engineering.
