My major research interests are in the areas of computational mechanics and material modelling with a particular focus on large deformation and failure of geomaterials. Leading the Monash Computational Geomechanics (MCG) Lab, I work on theoretical and computational modelling of geomaterials (e.g. granular materials, rocks and concretes). The objective of my research is to develop robust computational methods and advanced constitutive models to solve future challenges in geotechnical engineering and geomechanics, with reference to related engineering applications. Typical examples of those problems include slope stabilises and slope failures, gravity-driven flows (e.g. granular flows, landslides and avalanches), coupled flow-deformation in porous medium (e.g. multi-phase flows, internal erosions, hydraulic fracturing), damage and fracture of brittle and quasi-brittle materials (e.g. rock fractures, fatigue in pavements), thermal-hydro-mechanical coupling processes (e.g. expansive soils and desiccation cracking in soils) and soil-structure interactions. Through my research, I aim to advance our understanding of underlying processes that govern the macro-behaviour of geomaterials and make use of these understandings to further advance our current predictive capabilities with references to real-life engineering applications.
