Diana Rios

Profile

I am a PhD researcher at the University of Leeds, undertaking my doctoral studies through the EPSRC SATURN Centre for Doctoral Training (CDT). My research focuses on investigating porosity changes and stress mechanics of corroding nuclear waste under confined expansion, contributing to a better understanding of material behaviour and long-term challenges associated with nuclear waste management.

I hold an MSc in Engineering Geology and a BSc in Physical Geography. My academic background has provided me with a strong foundation in engineering geology, geotechnics, hydrogeology, soil and rock mechanics, and the behaviour of geological materials under changing environmental conditions.

During my MSc at the University of Leeds, my research investigated the effects of rainfall, drought-rewetting cycles and transient seepage on the stability of historic canal embankments. This involved integrating ground investigation data, laboratory testing, groundwater monitoring and numerical modelling to assess seepage behaviour and slope stability.

My doctoral research builds on my background in geotechnical engineering and material behaviour, examining how corrosion-induced expansion influences porosity development and mechanical stresses within confined nuclear waste systems. I am particularly interested in understanding the interactions between material degradation, evolving pore structures and stress generation, and their implications for the long-term management of nuclear waste.

My wider academic interests include engineering geology, geomechanics and environmental sustainability. I am motivated by applying interdisciplinary scientific and engineering approaches to complex challenges in nuclear decommissioning, infrastructure safety and environmental protection.
