My research focuses on Iran and Central Asia (currently co-directing an active archaeological fieldwork program in Tajikistan). I specialize in archaeological textiles, studying textile materials from several vantage points. A palaeo-environmental perspective sets the stage for understanding fiber procurement, botanical dye materials, local ecologies of production, and differentiating between local and exotic sources. A material perspective enables sharper interpretation of value, symbolic resonance and other semiotic domains in the material record. From a physical and biochemical perspective, I utilize and sometimes modify high-resolution instrumentation and biochemical protocols in order to identify organic textile materials of a highly degraded nature, to better understand and more fully interpret information gleaned from rare archaeological textile remains.
