Research interests

Damien is a Research Fellow at Extremes dealing with the development of high pressure and high temperature experimental devices for national facilities. They allow is situ measurements of indirect physical observables or direct visualisation with synchrotron imaginging techniques. He is particularly interested in 4D characterisation of reacting and deforming rocks, subsurface resources and engineering, and reactive materials.
