I am a volcanologist, with broad interests in understanding how volcanoes work, and in the causes and consequences of volcanic activity.
Active research topics include: using historical sources to extend our knowledge of past eruptions and their societal impacts; understanding the response of volcanoes in once-glaciated regions to the end of the last glaciation; and piecing together records of past volcanism, and understanding contemporary volcanic risk, in the Ethiopian Rift Valley and the Eastern Caribbean.
