Jonathan is a Senior Engineer within the Atomic Clocks and Sensors group at the National Physical Laboratory (NPL), working on compact optical reference cavities and Sr+ optical clock technologies for potential use in future space missions. He joined NPL in 2020 following his undergraduate (Aerospace Engineering) and doctoral studies (Advanced Composites) at the University of Bristol.
With a background specialising in structural mechanics, Jonathan leads the design, analysis and assembly activities across a portfolio of projects funded by the UK and European Space Agencies and contributes to numerous publications and technical reports. Jonathan has also undertaken a part-time secondment with the NPL Partnerships team to help build strategies for developing our optical clock technologies for future use in space.
Jonathan is a Chartered Engineer and a Member of the Royal Aeronautical Society.
