MY RESEARCH INTERESTS
PALAEOCLIMATE AND PALEOENVIRONMENT
Provenance is often neglected in Quaternary environmental reconstructions. Sediment source, whether geomorphological (more immediate) or geological (the proto-source), can provide information about past landscapes and sediment transport including sediment production, atmospheric circulation, landscape evolution, and the wider dust cycle.
The key techniques I use to address provenance questions revolve around sediment geochemistry, in particular single grain zircons. Zircon U-Pb dating and isotopic hafnium content enable tracing individual loess grains to the bedrock(s) they were eroded from.
GEOCHEMISTRY - ZIRCON DATING AND ISOTOPES
Geochronology provides a basis for a robust comparison of environmental change between sites, regions, and archives. I am an OSL specialist with an extensive background in dating quartz and feldspars minerals, and using luminescence dating to determine the timing of loess deposition.
GEOCHRONOLOGY - LUMINESCENCE DATING (OSL)
Loess typically provides lithological evidence of past processes. In my research I focus on stratigraphic description and sedimentological proxies, such as grain size, colour, magnetic susceptibility, and organic and carbonate content.
