My research experience and interests are primarily focused on solving fundamental and challenging problems pertaining to the field of computational geomechanics. The motivation is to account for the geometric and material non-linearities involved in different geotechnical boundary value problems. This enabled me to engage in the learning and employment of advanced numerical techniques particularly designed to analyse large deformation problems. Appropriate utilization of such techniques can be instrumental in capturing the continuously evolving stress and displacement fields within the zone of influence. Furthermore, I have experience in the development, calibration and implementation of sophisticated soil constitutive models which can be a prerequisite in the precise modelling of complex soil mechanical response. I hold a specific interest in the analysis and design of offshore geosystems. Consequently, such modelling techniques and methodologies possess an immense potential in realising the associated complexities.
My research interest also includes exploring the fundamentals behind temperature induced alterations on soil mechanical behaviour. These geotechnical problems involve complicated thermal, hydraulic and mechanical processes that have significant mutual interactions. Inclusion of the phase changes for the pore fluid caused by temperature variations extends the multiphysical nature of these problems. Extensive investigation on such coupled aspects of soil response is crucial to comprehend as well as to provide solutions for various complex real-world challenges such as design of energy foundations, modern infrastructure development, and the impact of global climate change in cold regions.
I wish to continue my pursuit in performing exciting research in the aforementioned directions. Please feel free to contact me if you are interested to participate and contribute in these research directions.
