Geochemical Sediments and Landscapes

David J. Nash is Reader in Physical Geography at the University of Brighton. He is widely known for his publications on the links between silcretes, calcretes and landscape evolution in southern Africa, southwest Europe and the UK, as well as his broader research into the geomorphology of dryland regions and Quaternary to recent environmental changes in deserts.

Sue J. McLaren is Senior Lecturer in Physical Geography at the University of Leicester. Her research expertise is in terrestrial geochemical sediments (particularly aeolianites and calcretes), reconstructing palaeoenvironments in drylands, and geoarchaeology. Sue has worked extensively in northern and southern Africa, the Middle East, Mexico and the Caribbean, as well as in the Mediterranean and Borneo.
