My main research area is luminescence dating of sediments using quartz and feldspars. The focus of my research is on developing new luminescence dating techniques and improving them. Over the last decade, I have established several new dating techniques using quartz and feldspars.
Apart from the development of advanced luminescence dating techniques, my research also involves application of luminescence dating technique to answer important geological and archaeological questions. More recently, I have been more focused on dating key archaeological sites from Asia, Europe and Africa. My research is to develop new luminescence dating techniques and then apply them to these important archaeological and fossil hominin deposits to answer questions about human evolution, dispersals and extinctions.
To achieve the reliable dating task in luminescence dating, fundamental studies on the luminescence properties from quartz and feldspars are necessary. Understanding of the physical features of luminescence signals, such as thermal stability, anomalous fading and kinetics process of charge movements are important for developing reliable dating procedures. Since 2006, I have been studying the luminescence behaviours of quartz and feldspars from various geological settings.
