Current Interests

Dr Paul Weaver's research includes the application of piezoelectric and ferroelectric materials for novel sensing, actuation, energy storage and energy harvesting applications. A particular aspect of Paul's work is the science and measurement of functional materials' behaviour under extreme conditions such as harsh environments at elevated temperature or high humidity.

Biography

Paul graduated with an MA degree in natural science from Cambridge University, and a PhD from Southampton University in measurement of energy exchange in multi-phase flow. He has over 15 years' industrial experience in research and development of electro-mechanical systems and applications of functional materials, prior to joining NPL in 2008.

Paul is a chartered engineer, member of the IET and is a visiting Reader at Southampton University.
