Research Interests

My research focuses on volcano deformation analysis and understanding, from large caldera collapses to volcano flank instability and dike intrusions along rift zones. To reach this aim, I integrate different tools and datasets, such as remote sensing, fieldwork (structural volcanology), analogue and/or numerical modeling. One of my research goals focuses on long-term timescale analysis (101-104 years) to catch and understand the background deformation behavior of volcanic areas.
