Research Interests

My research interest is focussed on the understanding how damage mechanisms evolve in different types of materials and throughout their different length scales, in order to develop more accurate prevention techniques, allowing for a reduction in weight and cost by the industry. Furthermore, I am interested in Structural and Machine Design, focussing on Machine Dynamics, Lubrication and Contact Mechanisms, Fracture Mechanics and Fatigue and the Finite Element Method.
