The main thrust of my research is complex rheology of non_Newtonian fluids and its link to the fluid mechanics of these fluids. In particular, my research is centred around the yield stress fluids. These fluids can be found in many natural and industrial settings, for example mud, cements, crude oil, lava, etc. The applications of my research are so diverse ranging from controlling green house gas emissions from ponds to extrusion bio-printing. Methodologically, we exploit a high level of experimental, mathematical and computational techniques to study the rheology and fluid mechanics of yield stress fluids.
