Matthew Arran is a Research Associate at the LSRI, with a background in mathematics and a keen interest in applying it to our interactions with the natural world. Following doctoral work on sand dunes, in Cambridge, and research into landslide seismology, in Paris, he started his current project, on the potential economic impacts of a landslide-induced tsunami, in collaboration with Georgetown University’s Environmental Justice Program and the Institut de Physique du Globe de Paris. When not at work, he can often be found fixing bicycles, walking in the hills, or finding lakes in which to swim. He’s always happy to talk about sand!
