Profile

My research aims to better understand the hydromechanical behaviour of unsaturated soils, and its influence on civil infrastructure under changing climatic conditions,

Dr Tiago Gaspar

Tiago received his PhD from the University of Pretoria in 2020. As part of his doctoral studies, he led the element testing and centrifuge modelling aspects of an international research project, which aimed to investigate the design of wind turbine foundations constructed in expansive clays. During this time, he was a recipient of the Newton Fund UnsatPractice PhD exchange programme with Durham University, and conducted some work as a geotechnical consultant looking at issues related to swelling clays and piled foundations.

Following completion of his PhD, Tiago spent two years as a postdoctoral researcher at Durham University. In this position he gained experience in constitutive modelling of unsaturated soils, field instrumentation for the purposes of slope stability/landslide investigations, and developed advanced laboratory equipment for the element testing of unsaturated soils. He is also involved with a project in collaboration with the National University of Malaysia to investigate rainfall induced landslides. Tiago is also a member of the South African Institution of Civil Engineering (SAICE) Journal Editorial Panel.

Tiago joined the department in 2023. His research is aimed at understanding the hydromechanical behaviour of unsaturated soils under changing climatic conditions. Specifically, the investigation of rainfall induced landslides, the stability of tailings storage facilities, and the performance of various infrastructure constructed on/in swelling/shrinking clays. His research is conducted by incorporating a combination of centrifuge modelling, element testing, and field monitoring. His work also involves collaboration with institutions across the UK, Europe, Southeast Asia, and South Africa.
