Dr Knock is a senior lecturer at Cranfield University and an expert in blast waves, ammunition safety and blood stain analysis. Clare's research on blast waves includes studying the shock waves from non-spherical chares such as cylinders, cuboids, crosses and truncated cones and the TNT equivalence of explosives. Her work on ammunition safety has included preventing mutual detonation in weapon systems. Clare's work on blood stain analysis includes developing methods for predicting the size and shape of blood and liquid impact onto porous, non-porous and granular materials, in particular fabrics, carpet sand and paper.
