PhD thesis: TBC

Provisionally, my research will focus on the development of a new theoretical model to describe liquid crystal elastomers (LCEs) - networks of cross-linked liquid crystalline polymers.

The physics of LCEs is incredibly rich. They are elastic, like conventional rubbers, but the liquid crystal component introduces elements of orientational order with responsive molecular shape. This combination, unique to these materials, can give rise to a great range of exotic properties. Perhaps the most striking is an ability to undergo dramatic and reversible deformations in response to an external stimulus like a change in temperature, making LCEs attractive candidates for use in micro-robotics and as artificial muscles.

Though these materials are well studied, it has recently become clear that current models cannot adequately explain some of their observed properties. I aim to develop a new comprehensive microscopic theory of LCEs which addresses this.

Who or what inspired you to pursue your research interests?

Physics reveals the great beauty of the natural world and I believe that the study of physics for its own sake is deeply valuable and meaningful. The modelling of soft systems often depends wholly on the branches of physics and maths which are to me the most appealing and inspiring. I’ve previously found related theoretical work in soft matter incredibly engaging and I thank my masters supervisor for his guidance and example. I owe a lot to the authors of the many great physics texts which have shaped and nurtured my interests throughout my studies.
