Jack graduated in 2016 from Bournemouth University with an honours BSc in Archaeology. His degree course focused heavily on British Archaeology and remote sensing applications, with a dissertation analysing the Iron Age to Roman Co-Axial Field systems of the Yare-Bure river valley. The project involved analysing datasets alongside select air photos and discussing the results with recent theories surrounding planned landscapes. As part of Jack’s degree course, he opted to undertake a year in industry with the New Forest National Park Authority. Within this role, Jack worked as part of a project team to deliver geophysical survey, assisted with research including extensive LiDAR and ground-truth survey, managed teams of volunteers and helped to deliver public engagement events with the archaeology team.
