Research

My main research interest is in experimental studies of rate-dependent plasticity in materials with a particular focus on the effect of microstructural interfaces, such as grain boundaries and interphase boundaries, on local variations in plasticity in a material.

My lab at Western University is equipped with High Temperature Nano/Micro-Indentation facilities. My research group also makes use of specialized materials characterization facilities found at Western and at other Universities in Southern Ontario.
