I am a geologist, glaciologist & material scientist, who is charmed with the beauty of minerals' microstructures. From laboratory experiments, I correlate minerals' microstructural development with their mechanical behaviour and build experiment-based flow laws. From numerical modelling, field investigation, and ice-core study, I test and upscale the flow laws to natural conditions to estimate the deformation condition and quantify the rheology of terrestrial ice flow and lower crust / upper mantle.
