Structure from Motion

Much of my field documentation uses Structure from Motion from aerial and terrestrial imaging in order to generate high-precision geospatial data. My projects incorporate these methods into our normal workflow at scales ranging from landscape survey to archaeological contexts to individual objects.The final output of these models are high-precision DEM, orthomosaic, and vector datasets that can be integrated into GIS applications.

GIS

Using real-time vectorization on devices, geospatial datasets, and archaeological data, my survey and excavation data are fully integrated into GIS databases were they are managed and analyzed.

Material Analysis

I conduct regular sedimentology to characterize sediments for two primary purposes: on one hand, I analyze samples from landscape contexts in order to characterize Holocene geomorphology as a means for assessing environmental dynamics; on the other hand, I analyze archaeological building materials, namely sundried mud-bricks, in order to interpret the chaîne opératoire involved in the process of manufacture and construction. 

I use XRF to characterize bulk elemental compositions of materials, including metals, sediment, and stone. In my fieldwork, I regularly collaborate with several specialists to conduct geoarchaeological research dealing with chronometric dating, paleomagnetism, infrared spectroscopy, phytolith analysis, and micromorphology. Likewise, I am currently coordinating an international team of collaborators studying aDNA, pathologies, diet, residues, mobility, environment, seasonality, provenience, and taphonomy from an exceptional Bronze Age burial context.
