Thomas Willett, PhD, PEng (He/Him)

Professor Willett’s research interests concern the mechanics and engineering of skeletal biomaterials and tissues. He specializes in:
1) Bone Tissue Mechanics - developing improved understanding of the mechanisms that determine the mechanical behaviour and failure of bone and how collagen modifications due to ageing, disease, irradiation, and other causes alter these mechanisms and the mechanical behaviour of the tissue.
2) Engineering of bone-inspired materials for skeletal reconstruction –

• Mechanics of Biomedical and Biological Materials
• Bone Mechanics, especially Fracture Mechanics
• Bone Quality and Fragility
• Biomaterials & Tissue Engineering
• Additive Manufacturing/3D Printing
• Mechanical testing
