Profile

Dr Helen Roberts joined the Institute in 1998 as a post-doctoral research assistant in the Aberystwyth Luminescence Research Laboratory, and was appointed to a lectureship in Physical Geography in 2005. Prior to coming to Aberystwyth, Helen worked in the Luminescence Laboratory at the University of Durham, and also taught in the Department of Geography at the University of Exeter.

Research Interests

The development and application of luminescence geochronology, with particular interest in rates of geomorphic change, and also studying deposits of wind blown dust ('loess') and the dust record. Dust in the atmosphere has a potentially significant impact on the climate system, but its role in climate change is not well understood. The application of high resolution OSL dating to loess provides an unparalleled record of changing dust deposition rates, giving important information regarding atmospheric dust fluxes for use in climate models.
