Volcanic Margins Research Consortium


Career Research Interests


Volcanology in general, pyroclastic sedimentology, and the mass movement of debris across the Earth's surface following geo-catastrophes. Primarily use field studies of deposits to derive information about emplacement processes. Application of volcanology to the petroleum and mining industries. Specifically interested in:

  • impact of volcanic and igneous rocks on hydrocarbon systems (Volcanic Margins Research Consortium).
  • the transport and deposition of tephra by pyroclastic density currents;
  • basaltic volcanism, effusive and explosive;
  • volcanic edifice growth and evolution, encompassing all scales from monogenetic cones, to calderas, ocean island volcanoes and large igneous provinces;
  • aggregation mechanisms in atmospheric dust clouds applied to volcanic eruptions and meteorite impacts;
  • kimberlite volcanism and conduit processes;
  • dispersal of ejecta following large meteorite impacts.

I currently have ongoing research projects in El Salvador (AD563 Tierra Blanca Joven eruption of Ilopango); Campi Flegrei and Ischia, Italy; Tenerife; Iceland, UK Lake District.
