In my lab, I analyze ‘invisible’ artifacts with the help of the PartAn3D, a dynamic image particle analyzer (starting int he Spring of 2024, the lab is in Stevenson SC2337A). I collect soils, mortars, and other granular dry materials from archaeological sites and use the PartAn3D to measure several dozen variables for\u00a0each particle in a sample. To define the shape of the ancient artifacts I am looking for, I use experiments. In 2019, I invited stone-knapper Mike McBride to make\u00a0stone tools from chert and obsidian. Together with graduate students, I have also participated in knap-ins.\u00a0We have\u00a0collected all the debris that the stone knappers produced and used it to define stone-knapping debitage. Machine learning and other data science approaches then allow me to identify these microartifacts in my archaeological samples.<\/p>\n
