Research interests

I am interested in the growth of active normal faults and how their slip-rates and growth control earthquake recurrence and seismic hazards. Active faults make beautiful landscapes, but kill people through building collapse.

Research roles

Current research

I am currently seismic hazard working in Italy and Greece. The work involves:

  • Structural geology fieldwork and mapping, concentrating on the geometry, kinematics and rates of deformation of active normal faults, and utilising kinematic measurements, shallow geophysics and LiDAR laser scanning.
  • Quaternary and Holocene dating of deformed geomorphology, through study of Holocene fault scarps and Quaternary marine terraces, using 36Cl cosmogenic exposure dating and U/Th coral dating.
  • Observations and modelling of rivers deformed by active normal faults.
  • Developing theoretical and numerical models of fault growth.

I am also working on Martian faults as exceptional exposure aids understanding of terrestrial faults. I am involved in studying deformation of the surface of Mars using NASA (MOLA; MOC; VIKING; HiRISE) data.
