My research interest is focused on physics-based modelling and investigation of thermoelastic and dynamic phenomena for improved design and control of manufacturing and tribological systems. This research combines conceptual and theoretical development with numerical modelling and simulation, as well as experimental investigation and validation. Currently, my graduate students, Canadian and international collaborators and I are working on the following topics: Physics-based modelling of high speed machining HSM, multi-variable optimal numerical control of thermal deformation of machine tool structures, dry and minimum quantity lubrication machining, identification of materials constitutive laws and shear localization onset in HSM, thermal constriction phenomenon in multi-layer coated tool, effect of edge preparation on tool wear, characterization of the machinability of composites, laser assisted machining of nickel alloys, impact fretting wear and fretting fatigue in nuclear and aerospace components, modelling of friction-induced temperature rise in fretting considering the random distribution of contact asperities, thermometric design considerations in temperature measurement.
