Teaching

Research

Professor Helen M. Roberts is Co-Director of the Aberystwyth Luminescence Research Laboratory (ALRL), where she has been based for over 20 years. During this time she has helped to develop the Aberystwyth Luminescence Research Laboratory’s international reputation for excellence in luminescence research through the development of both pure and applied research strands. Her research focuses on the development and application of luminescence methods for dating Quaternary sediments, with particular interest in rates of geomorphic change, coastal change, and long terrestrial records of climatic and environmental change. Helen’s current research includes deciphering the record of past environmental change preserved in lake sediments in Africa, and the links to human evolution, innovation, and dispersal of our human ancestors. She is also interested in the wind-blown dust deposits known as ‘loess’; these deposits contain important information about past levels of dust in the atmosphere, which can be used in climate models to study the impact of dust on the climate system, and to improve our understanding of the role of dust in past and future climate change.

She is Vice President of the Stratigraphy and Geochronology Commission (SACCOM) of INQUA, the International Union for Quaternary Research (2019 – present).
