Solving Complex Engineering Problems Through Research

My research explores the behavior of soils and infrastructure under different conditions, helping engineers design stronger, safer, and more sustainable structures.

Featured Research Topics

efficiency of energy piles in the saturated and unsaturated soils

This research examines the thermal and structural efficiency of energy piles embedded in saturated and unsaturated soils. It focuses on heat transfer mechanisms, soil-structure interaction, and the impact of moisture conditions on pile performance, contributing to sustainable energy solutions in variable geotechnical environments.

Hydro-mechanical behaviour of Tropical soils

This study explores the hydro-mechanical response of tropical soils under varying suction and stress conditions. Emphasizing their unique fabric and mineralogy, it links water retention, permeability, and shear strength to improve the prediction of slope stability, settlement, and foundation performance in tropical regions.

Thermo-mechanical behaviour of Tropical soils

This research investigates how temperature influences the mechanical response of tropical soils. By evaluating changes in stiffness, strength, and thermal conductivity, the study reveals the complex interactions between heat flow and stress-strain behaviour, providing insights into infrastructure performance under climate-driven thermal variations.

Microstructural Evolution of Soil during extreme wetting

This study examines how extreme wetting affects the microstructure of soils, particularly in tropical environments. Using imaging and porosimetry techniques, it identifies changes in pore structure, fabric arrangement, and particle bonding, and links them to macroscopic behaviours such as volume change, permeability, and strength loss.
