I am a post-doc at Imperial College London, where I work with Kim Jelfs. I completed my DPhil in Inorganic Chemistry at the University of Oxford with Andrew Goodwin, where I used coarse grained models to understand the formation and phase behaviour of complex materials. In the Jelfs group, I am interested in using coarse-graining to inform molecular materials design and develop our understanding of molecular crystal formation.

How molecules pack has vital ramifications for their applications as functional molecular materials. Small changes in a molecule’s functionality can lead to large, non-intuitive, changes in their global solid-state packing, resulting in difficulty in targeted design. Predicting the crystal structure of organic molecules from only their molecular structure is a well-known problem plaguing crystal engineering.

Developing models to represent structural phase behaviour is often a complex task due to the large number of degrees of freedom at play. My research aims to coarse grain these degrees of freedom, focusing on the most dominant interactions, and use these coarse-grained models to understand organic solid state phase behaviour. While presenting a lower computational cost route for predicting molecular crystal packing, coarse-grained models also allow for the development of design rules.
