Project Description

Energetic materials (explosives, propellants and pyrotechnics) are used in a broad range of public and private sector applications. The design of novel, safe materials is therefore of critical importance. At present, the development of new energetic materials requires production and experimental testing, with a posteriori rationalization of its properties. This poses obvious safety hazards, yields limited fundamental understanding of structure/property relationships, and does not permit the targeted design of new materials with tailored properties.

Recent work in our group has shown that mechanical impact sensitivity can be predicted from first principles simulation if the crystal structure of a material is known. [1-3] Combining this modelling ability with advanced crystal structure prediction tools [4-6] therefore offers the potential to computationally design new energetic materials with tailored properties, and to explore the broader relationship between structure, energetic power and material safety.

The successful candidates will possess, or expect to obtain, a first class or upper-second class undergraduate degree (or equivalent) in chemistry. Essential qualities include a strong background in computational modelling. Other essential attributes are good presentation and communication skills (written and oral). In the first instance, informal enquiries (accompanied by a CV) should be directed to: Prof. Carole Morrison, School of Chemistry, University of Edinburgh, David Brewster Road, Edinburgh EH9 3FJ, UK. Email: and Prof. Graeme Day, School of Chemistry, University of Southampton, Southampton, SO17 1NX, Email:

The University of Southampton and the School of Chemistry both hold Athena SWAN Silver Awards, reflecting their commitment to equality, diversity and inclusion, and particularly to gender equality.

Funding Notes

The two studentships (one based at Edinburgh, one in Southampton) are fully funded by the U.S. Air Force for 3.5 years, covering tuition fees and an annual stipend (starting at ca. £15k per annum) for a candidate satisfying EPSRC’s criteria (View Website). Together, the students will develop a computational screening methodology for energetic materials discovery. The student based in Edinburgh will develop the first principles simulation of impact sensitivity and the Southampton student will develop the use of crystal structure prediction.
