Bronagh has been working in archaeology since 2014, where she got her first job working through the summer between years at university. She continued working part time throughout her degree, specializing in environmental archaeology. Since graduating in 2016, Bronagh has developed specialist skills within archaeological survey, as well as working on a wide range of sites from large-scale Roman settlements to smaller, deeply stratified sites. Notably, Bronagh was part of a team excavating at the nationally important Lincoln Eastern Bypass project, during which she took part in excavations of a Roman villa as well as an early Christian cemetery and Mesolithic flint scatters.
Since joining AOC Archaeology in May 2018, Bronagh has worked on a multitude of sites, including the important excavations in Sandy of a Roman settlement, including the original town walls and a small cremation cemetery, in which Bronagh found two complete vessels. As well as working in Sandy, Bronagh has been part of the HS2 works and has supervised several watching briefs, including a large site on the Isle of Sheppey, where both Roman and Medieval remains were found.
