Richard Bailey is a lecturer in Geochronology, Director of the School of Geography and the Environment Luminescence Dating Laboratory and Tutorial Fellow of St Catherine's College. He is also the Departmental Safety Officer. Prior to September 2006, he held positions including a Lecturership in Physical Geography (Royal Holloway, University of London), NERC Postdoctoral Research Fellowship (University of Oxford), Research Fellowships at St John's College and the Research Laboratory for Archaeology and the History of Art (University of Oxford); and a Stipendiary Lectureship in Physical Geography, St Catherine's College (Oxford).
He is a member of the Editorial Board of Quaternary Geochronology and of the Review Panel for the luminescence research journal Ancient TL. He also acts as a reviewer for several other international journals in the fields of geography, environmental change and applied physics (including Quaternary Science Reviews, Holocene, Palaeogeography-Palaeoclimatology-Palaeoecology, Radiation Measurements, Journal of Applied Physics) and has reviewed grants for NERC and the Austrian Science Fund (FWF). Invited contributions include journal articles for Quaternary Science Reviews and Radiation Protection Dosimetry, and oral conference presentations for the International Conference on Solid State Dosimetry and the International Quaternary Research Association (INQUA). He is a member of several learned societies including St John's College, Oxford, the American Geophysical Union, Quaternary Research Association and the Royal Geographical Society. He is also the creator of WikiLum, a 'wiki' for the luminescence community which acts as an internationally-fed database, message board and file-swapping point for those involved in luminescence dating.
Dr Bailey's research is focused primarily on the development of Luminescence Dating techniques and their application to research topics in Quaternary science, including climate/environmental change, geomorphology and human evolution/dispersion. His work on the development of luminescence methods involves laboratory-based experimental work, the development of numerical models (of quartz electron population dynamics) and of statistical models of dating results. He also has a more general interest in quantitative methods and their application in physical geography.
Aspects of this work have been funded by the Natural Environment Research Council, Leverhulme Trust, Royal Society, Australian Research Council, private commercial contracts and internal University grants.
