Geography

Fields of Research

  • Processes, hazards and risks of high energy flows (e.g. tsunamis, lahars...)
  • Computer vision, image analysis and automation (aerial photographs, videos...)
  • Non-linear dynamics and applied mathematics to geomorphology

Researcher Summary

My research deals with the chain of environmental-processes that act at the landscape scales, integrating hydrology, sediments, vegetation and human activities, with an emphasis on hazardous earth-processes.
- Up to present I have been working mainly on the tsunamis of Sumatra (2004), Java (2006) and Tohoku (2011); on the volcanoes Semeru, Merapi and Merbabu in Indonesia, and on the volcanoes Unzen-Fugendake, Towada and Numazawa in Japan. More recently, I have also started to develop a portfolio on tsunamis and floodplain/estuarine processes in the Canterbury area (New Zealand).
This apparently broad research scope aims at breaking free from the disciplines that we are educated in, in order to look into scientific questions from a different stand.

Subject Area: Disciplines

Future Research

  • Flood hazards and management in Japan
  • River restoration and floodplain analysis in Japan
  • Development of the AMS method (Anisotropy of Magnetic Susceptibility) on unconsolidated sediments in New Zealand
  • The combined effects of rainfalls and wind on sediments
  • Debris flow triggering processes in the light of climate change

Key Methodologies

  • Applied remote sensing and GIS
  • GPR Ground Penetrating Radar
  • AMS: Anisotropy of Magnetic Susceptibility
  • Matematical and physical modelling (Modflow, NaSt3DGP, Hec-HMS, Hec-RAS, Gerris, Matlab, Octave...)
  • 3D reconstruction with 3DS Max, Maya...
  • Digital signal processing using Matlab
