Research interests

Conditions for fault creation and fault re-activation. Critical stress state. Instability/sliding phenomena. Frictional behaviour (focus on stable sliding and stick-slip sliding modes). Interaction of sets of fractures and faults.
Induced seismicity due to fluid and gas flows. Understanding the role of pore pressure, fluid/gas flow and temperature variations on the creation and/or re-activation of micro-faults at the laboratory scale.
Localised deformation. Nucleation and evolution of deformation bands, such as dilatant and compactant shear bands and shear-enhanced and compaction bands at the laboratory scale. Transition from brittle to ductile behaviour.
Application of a range of experimental methods with different resolution and sensitivity such as: a) X-ray Computed Tomography, b) Neutron Radiography and Tomography, c) 3D Digital Image Correlation, d) Passive wave monitoring (e.g. Ultrasonic Tomography), e) Active wave monitoring (e.g. Acoustic Emission monitoring), f) Source Mechanisms and Moment Tensor Analysis, g) Microstructural analysis based on optical and scanning electron microscopy.
Pore-scale characterisation, pore network extraction and fluid flow simulations.
Shear experiments on 2D (analogue) granular materials. Investigation of the impact of different shape of grains on the mechanical behaviour of a granular material. Comparison of experimental results with numerical simulations using Discrete Element Method (Molecular Dynamics).

Fingerprint Fingerprint is based on mining the text of the persons scientific documents to create an index of weighted terms, which defines the key subjects of each individual researcher.
