Biography

Dr Bo Su is Professor of Biomedical Materials within the Bristol Dental School at the University of Bristol. He has research experience in materials for over 30 years, including structural, functional and biomedical materials. After obtaining his PhD at the University of Birmingham in 1998, he spent five years as a post-doctoral researcher at Imperial College and Birmingham University respectively and was awarded an EPSRC Advanced Research Fellowship in 2003. He joined Bristol as a Senior Lecturer in 2005 and was promoted to Reader in 2009 and Professor in 2013. He has published more than 100 journal papers and holds two patents. He has received funding from EPSRC, BBSRC, MRC, NIHR, GWR, charities and industries.

Bo is a Fellow of Institute of Materials, Mineral and Mining (FIMMM) and a member of EPSRC Peer Review College.  His research interests are in materials processing and fabrication, including micro- and nano-fabrication and surface patterning of titanium metals, ceramics, polymers and composites for biomedical applications. He leads the Biomaterials Engineering Group (bioMEG) and is currently the School Postgraduate Tutor.

Abstract

Natural materials such as human teeth and bones have remarkable mechanical properties. However, nature grows these biological materials from a bottom-up approach using a biologically controlled self-assembly process. In this talk, I will discuss a top-down approach from a powder processing route for the fabrication of hierarchically structured ceramic/polymer or metal/polymer composites to offer cost-effective engineering solutions for potential applications in orthopaedics and dentistry. Freeze casting technique was used to create such hierarchical structures in metals (e.g. Ti) and ceramics (e.g. alumina). Biomimetic composites were produced with infiltration of polymers or hydrogels. The composites possess anisotropic, graded and interpenetrating multi-phase microstructures with performance surpassing conventional monolithic and isotropic materials currently used in clinic.
