Alicia Medialdea is a postdoctoral researcher at the Department of Geography. She is working with Mark Bateman on the luminescence dating for Britice-Chrono project.

Alicia was awarded her PhD from Universidad Autonoma de Madrid in February 2013. Her research focused on the luminescence dating of flash flood deposits in the Iberian Peninsula. This research project was undertaken as a collaboration between the National Museum of Natural Sciences in Spain and the Nordic Laboratory for Luminescence Dating in Denmark.

Research interests

Her research interests include geochronology of the Quaternary and studying the physics involved in luminescence dating procedures.

Current research

Her current research is focused on:

  • Determining the time frame of the last British and Irish ice sheet by applying luminescence dating to date glaciated sediments from different locations along UK and Ireland.
  • Understanding the impact of fault activity for environmental risk assessment.
  • Developing the protocols in luminescence dating for establishing precise flood chronologies.
  • Exploring the physical properties of the luminescence signals with the aim of proposing new protocols to extended the age range and improve the accuracy of equivalent dose estimation.
