Research Interests
Dr. Esdras Ngezahayo’s research interests lie at the intersection of geotechnical engineering and climate resilience. His work addresses the behaviour of problematic soils, particularly in the context of rural and urban infrastructure subjected to climate change. Key topics include erosion and soil stability, shrink-swell phenomena in clay soils, slope stability, buried utilities, and transportation geotechnics. He is actively engaged in investigating sustainable materials for road construction, including rice husk ash and modified epoxy asphalt, and has contributed to assessing geotextile effectiveness in railway subgrades. His interdisciplinary work also explores equity in transportation systems for vulnerable populations. With a growing research portfolio, Dr. Ngezahayo aims to contribute toward net-zero goals by focusing on sustainable geotechnical solutions for developing countries, particularly in Sub-Saharan Africa. He is a prominent contributor to global discussions on infrastructure adaptation and has presented his work at leading international conferences and in collaborative research initiatives.
Awards
Dr. Ngezahayo’s academic journey is decorated with numerous awards and recognitions. He secured full PhD studentship funding twice to investigate geotechnical challenges like gully erosion and electrokinetic stabilization of clay soils, funded by EPSRC and the University of Birmingham. His laboratory received infrastructure grant to modernize testing facilities. He received the ICE West Midlands Commendation and CIHT-PIARC Awards for best research in sustainable mobility and adapting road infrastructure to climate change. The Horizon Award for teaching and learning excellence was bestowed by the University of Birmingham, reflecting his pedagogical leadership. He also earned a C-DICE micro-credential badge for innovation in net-zero-aligned research. Earlier recognitions include the Commonwealth Scholarship for PhD studies and a national scholarship for his MSc. These accolades underscore his contributions across academia, research innovation, and professional development in engineering for global sustainability and education excellence.
