My research aims to understand and predict the behaviour of geomaterials and geotechnical systems under complex loading, large deformation, and failure. I combine computational geomechanics, physical modelling, and increasingly data-informed approaches to address fundamental and applied problems in offshore engineering, soil–structure interaction, progressive failure, and geohazards. Current research activities are organised around four interconnected themes.

Offshore Geotechnics   •   Computational Geomechanics   •   Progressive Failure & Geohazards   •   Data-Informed Geomechanics 

Offshore Geotechnics & Seabed–Structure Interaction

This research theme investigates the behaviour of offshore foundations, marine sediments, and seabed–structure systems subjected to installation, environmental, monotonic, and cyclic loading. Particular interests include offshore wind foundations, cyclically loaded monopiles, seabed characterisation, penetration problems, subsea infrastructure, and scour. Computational modelling is combined with physical modelling and experimental observations to improve the understanding and prediction of offshore soil–structure interaction.

Topics: Offshore wind foundations · Monopiles · Marine sediments · Seabed characterisation · Penetration problems · Soil–structure interaction · Scour


Computational & Large-Deformation Geomechanics

This theme focuses on the development and application of advanced computational methods for geotechnical problems involving large deformation, failure, and post-failure behaviour. Particular emphasis is placed on the Material Point Method (MPM), finite element methods, meshless approaches, limit analysis, constitutive modelling, and coupled formulations. The objective is to develop robust computational frameworks capable of modelling the complete response of geotechnical systems from initial deformation through failure and large-scale post-failure movement.

Methods: MPM · FEM · Large-deformation analysis · Limit analysis · Constitutive modelling · Meshless methods · Coupled formulations


Geohazards & Progressive Failure

Research in this area addresses the initiation, evolution, and consequences of progressive geotechnical failure. Current interests include slope instability, landslides, strain localisation, progressive failure, and post-failure runout, with particular attention to the influence of spatial variability, soil–water interaction, and large deformation. The long-term objective is to improve the mechanics-based assessment and prediction of geotechnical hazards and contribute to the development of safer and more resilient infrastructure.

Topics: Landslides · Slope instability · Progressive failure · Post-failure runout · Spatial variability · Soil–water interaction · Geotechnical risk


Physics-Informed & Data-Driven Geomechanics

This research direction explores the integration of physics-based computational modelling with data-driven methods to improve the interpretation, identification, and prediction of geotechnical systems. Areas of interest include inverse parameter identification, surrogate modelling, uncertainty quantification, model updating, and efficient prediction of complex geotechnical behaviour. The broader objective is to combine observations, mechanics-based models, and computational intelligence to develop more reliable and computationally efficient approaches for geotechnical prediction.

Topics: Inverse analysis · Parameter identification · Surrogate modelling · Uncertainty quantification · Physics-informed learning · Data assimilation · Predictive modelling


Research Approach

Across these themes, my research seeks to connect fundamental soil mechanics, advanced computation, experiments, and observations. The aim is not only to simulate geotechnical behaviour, but to develop modelling and interpretation frameworks that improve our understanding of the mechanisms governing deformation and failure and ultimately support more reliable engineering prediction.

Teaching Philosophy

My teaching philosophy emphasises fundamental understanding, physical interpretation, and the critical use of experimental and computational tools. Students are encouraged not simply to follow established procedures, but to understand why an experiment, analytical method, or numerical model works, recognise its assumptions and limitations, verify results, and relate observations back to the physical behaviour of soils and geotechnical systems.

I aim to develop students' ability to move from observation → physical understanding → modelling → interpretation, while promoting independent thinking, careful verification, and research-oriented problem solving.

My academic journey combines advanced training in geotechnical and earthquake engineering with international research experience in computational geomechanics, offshore geotechnics, large-deformation analysis, and soil–structure interaction. My research career has included academic and research appointments across India, Hong Kong, Finland, the Netherlands, the United Kingdom, and the United Arab Emirates.
