During his professional career as a field archaeologist (2008-2013), Sibrecht worked in the governmental and private sector (Belgium and France), where he developed his research skills both on terrain and during post excavation. From 2013 onwards Sibrecht started a PhD project at Ghent University. During this project he investigated Roman stone implements as an important proxy to study socio-economic processes within the Gallo-Roman society (e.g. provenance, distribution networks, technology, etc.).
After finishing his Phd in 2018, Sibrecht continued his academic career with the establishment of a reference collection for stone and ceramics (FWO Hercules project) at the Department of Archaeology (Ghent University). This ongoing FLEPOSTORE (Flemish pottery and stone reference collection) project is a collaboration with the Department of Geology from Ghent University and (co-)supervised by Prof. Dr. W. De Clercq, Prof. Dr. P. Crombé, Prof. Dr. V. Cnudde and Prof. Dr. T. De Cock.
Since 2021 he started a new postdoc project funded by the Special Research Fund: “Whetstones” on the cutting edge. Understanding the cultural
biography of Roman and medieval macrolithic tools through the application of use-wear analysis. From domestic and agricultural activities to specialized craft productions. For this project he will focus on the application of use-wear analysis on historic macrolithic tools. An approach that has proved its merits in prehistoric archaeology, but which is highly innovative within historical archaeology. In this project he will focus on tools that are generically determined as “whetstone”, referring to the sharpening function for the cutting edge of metal implements. Their specific function could be much more diverse than is generally assumed. As such they can contribute to the wider socioeconomic debate on domestic, agricultural and (specialized) craft activities.
