Staff profile

Alexander manages the Digital Visualisation Laboratory and teaches subjects ranging from photography and 3D scanning to GIS to undergraduate and postgraduate students (and provides workshops for our PhD students). He also assists our post-docs, PhD students, and UG and TPG students in developing their research methodologies on an individual basis. He manages the Departmental digital equipment such as specialised 3D scanners (and in the near future our 3D printers), photography gear, software, and other audio-visual equipment. He provides our students and staff with the tools and methodological knowledge they need to conduct their research. Alexander also produces videos and handles photography for our department, which are shared through our YouTube channel and/or on social media.

He joined Durham University in 2021, after having obtained a MSc (cum laude) in Digital Archaeology from Leiden University, the Netherlands, and a BA in Mediterranean Archaeology (with a second specialisation in Near Eastern Archaeology). During his BA studies, he also completed the extracurricular “Honours College: Crossing the borders in World Archaeology” track, with excellent grades (equivalent of cum laude).

Alexander has experience with archaeological excavations and fieldwork all over the Mediterranean, as well as in the Netherlands, Germany, and the United Kingdom. This fieldwork ranges from geophysical surveying to 3D drone surveys, as well as conventional excavations. His own research focuses on the spatial analysis of the built environment and 3D modelling. He specialises in Structure-From-Motion (photogrammetry), with both conventional cameras as well as drones and multispectral photography, but also other digital data (including 3D) acquisition methods.

Since 2018, he has been a member of CAA International (“Computer Applications and quantitative methods in Archaeology”), and is one of the founding committee members of the CAA Special Interest Group "3D Spatial Analysis" (3D Spatial Analysis - CAA International). At the CAA 2021 conference in Cyprus, he was the main organiser of the “Exploring the possibilities of 3D Spatial Analysis” session.
