About the Author

Technical Product Manager, Oxford Instruments

Dr Katherine MacArthur read for her Masters in Engineering and Materials Science at Corpus Christi College Oxford where she developed her passion for electron microscopy. When she moved on to her DPhil, she delved deep into the world of high-end aberration corrected scanning transmission electron microscopy (STEM) specialising in quantification of electron images and EDS. She continued to push the limits at atomic resolution trying to count atoms and quantitatively measure the localised structure of core-shell catalyst nanoparticles. Later moving to the Ernst Ruska Centrum in the Forschungszentrum Juelich, Kate continued to play with TEMs understanding the fundamental limitations of EDS quantification in a STEM and expanding into both in-situ heating and gas experiments. In early 2023 after a short parental leave, Kate relocated back to the UK stepping away from the dark room of TEMs to join the Technology team at Oxford Instruments. In this role she carried on developing algorithms for improved EDS processing, including contributing to bringing the Unity detector to market and expanding our open-source data export. In September 2024, she changed roles to become Technical Product Manager for AZtec. In this new role she interfaces between the software and marketing teams aiming to support technical solutions for our software development and ensuring a uniform end product for our customers.
