Areas of expertise
- Smart Materials
Dr Chris Shaw obtained his BSc(Hons) in Chemistry from the University of Liverpool in 1985 before joining Cranfield University to study an MSc in Molecular Electronics (Thesis: ElectroRheology (1987)) and PhD in Molecular Electronics (Thesis: Polymeric Materials for Piezoelectricity and Second Harmonic Generation (1991)). He subsequently returned to Cranfield to join the Microsystems and Nanotechnology Group in 1997, and is now a Research Fellow in the Surface Engineering and Precision Institute within the Manufacturing Department. Recent project work has focused on ferroelectric, piezoelectric and pyroelectric materials and their applications. Dr. Shaw has acquired many years experience in cleanroom processing techniques within these research projects and provides support within the cleanroom facility on other projects, and on MSc teaching courses.
