Intrinsic and Extrinsic Control of Bioinspired Freeze Casting
Research into complex control of the bioinspired freeze casting process for structural and biomedical materials is ongoing in the Laboratory for Bioinspired Science and Engineering. This research focuses upon control through both intrinsic (enacted through internal chemical processes) and extrinsic (enacted through external forces) means to imitate the complex structures and impressive mechanical properties of biological materials.

Biomedical Dental and Bone Cements
Novel, glass- and microsphere-based biomedical dental and bone cements are being researched that hope to improve healing and patient outcomes by tailoring the cement microstructure and properties. By combining biology, chemistry and engineering we are working to create novel functionalities in bone cements while maintaining biocompatibility and promoting cell health.

Structural Design of Biological Materials
To perform bioinspired science and engineering, a deeper understanding of the properties and structures present within biological materials is required. This can be achieved through the process of biological materials science, which employs the tools and techniques available in the fields of engineering, chemistry and physics to theoretically and physically dissect natural organisms and understand how they thrive within their natural environments. In the Laboratory for Bioinspired Science and Engineering research is ongoing to understand the common structural design elements that are employed by nature to provide impressive mechanical properties.
