Position: Postdoctoral Researcher

Research interests:

Analogue and numerical models of volcanic processes. Special interest on collapse caldera processes. Creation and maintenance of the CCDB (Collapse Caldera DataBase) and webmaster of the IAVCEI (International Association of Volcanology and Chemistry of the Earth's Interior) and the GVB web sites. Currently working on a database of volcanic unrest signals.
