Research Interests

My research interest lie in Mineral Physics and Materials Science. Each study in these two disciplines finds application to specific and different physico-chemical problems/investigations. The unifying theme that binds them is my primary goal of understanding the effects of high pressures and temperatures on solids and liquids, particularly as these parameters perturb and present the promise of control of physical properties. Knowledge of physical property behavior is pivotal for understanding many Earth processes as well as for tailoring specific responses in materials for applications. Many of these studies utilize equipment in the UWO Experimental High Pressure / Temperature Mineral Physics / Materials Science Laboratory.
