Dr Joao Mendes

Assistant Professor

Department: Mechanical and Construction Engineering

My research interests are primarily related to the understanding of the hydro-mechanical behaviour of unsaturated soils through laboratory and field experiments.

On one hand, understanding the impact of future climate and its effects on the stability and serviceability of earth structures (e.g. embankments); and, on the other, in the development and optimisation of new and existing methodologies for the study of unsaturated soils in laboratory (e.g. development of double cell triaxial cells) or as means of monitoring the water retention behaviour in earth infrastructure (e.g. in the improvement of high capacity tensiometers or HCTs). On the latter, I have a particular interest in understanding and how to prevent/minimise cavitation in HCTs.

Other research interests are related to the development of eco-friendly construction materials and to the capillary pressure build up in early age concrete.
