Geert J. Verhoeven is a senior scientist who left Belgium for Austria after obtaining his PhD in Archaeology from Ghent University in 2009. Geert is passionately curious about airborne and terrestrial imaging, image-based 3D surface modelling, metadata and semantic technologies, spatio-temporal reasoning, colour science, image processing, data visualisation and statistics. His endeavours in these fields aim to improve and standardise data acquisition, data management and information extraction procedures for the benefit of archaeology and the broader cultural heritage field.

Geert has a weak spot for research on contemporary graffiti because it illustrates that archaeological methods and cultural heritage frameworks also apply to yesterday's social practices and cultural artefacts, not solely those of the remote or ancient past. This vision transpired in INDIGO, an academic project on contemporary graffiti coordinated by Geert and funded by the Austrian Academy of Sciences.

Most of Geert's academic work is open-access and shared via various platforms. He is a member of various international organisations (AARG, CIPA Heritage Documentation, ISAP and ISPRS), sits on six editorial boards and has reviewed papers for over 60 international journals. Some of his photos appeared in National Geographic, newspapers and local magazines.
