Biography

I took up my current position in 2007. Prior to this I completed a PhD in Computational Solid State Chemistry with Prof SC Parker before undertaking postdoctoral research in Bath and in the Materials Science department in Cambridge, where I was part of a consortium modelling the interface of biological molecules with mineral surfaces.

In addition to teaching physical chemistry, I am actively involved in researching many aspects of solid state chemistry, particularly mineral surfaces, using computer modelling techniques as part of the Catalysis Research Centre in the Department of Chemical and Biological Sciences.

Research & Scholarship

Computational Solid State Chemistry

We use computational models to simulate the structure and stability of materials at the atomic level. These calculations are based on the Born Model of Solids and Molecular Mechanics force fields.

In such a model the forces are dominated by the long range electrostatic interactions, but the model also includes short range, van der Waals attractions, electron . electron repulsions and polarisability. Modelling provides a complementary approach to experiment by making predictions for future experiments and by interpreting existing data.

Bulk and Surface Defects

Crystals are rarely pure. Understanding how defects behave gives us an insight into the important physics and chemistry. Calculating the stability of bulk defects tells us the likely macro structure of the material and enables us to determine properties such as ion diffusion. Modelling can predict the optimum concentration of impurities on a surface.

Interfaces

Understanding how two phases interact makes it possible to predict new mechanisms for mineral growth. Organic molecules can cause crystals to grow in elaborate shapes. Modelling enables us to begin to understand the processes involved.

Crystal Growth

Being able to grow crystals in new, safer and greener ways is the focus of an important area of research. For example, the presence of a template causes the resulting crystal to be a particular shape. Modelling how nano particles aggregation gives us an insight into crystal nucleation.

Materials modelling is at its most powerful when the problem being considered is of direct interest to experiment. Consequently much of my research involves direct collaboration with related experimentalists both in the UK, internationally and, most importantly, within the Catalysis Research Centre in collaboration with Prof Brown and Dr Lamont.

Areas for Research Supervision

Developing new composites for Bio medical applications

Hydroxy-apatite (HA) has long been used as replacement bone because of its similarity in composition to bone. However its mechanical properties are inadequate and consequently there is a need to develop new materials which maintain the bioactivity of HA whilst increasing its mechanical strength. In this project we will use computer modelling to investigate the suitability of potential composite materials.

Atomistic simulation of fast ion conduction

Many inorganic materials conduct an electric current in the solid sate because one or more of the ions is capable of diffusing rapidly through the system. We will use MD simulations to study how the choice of dopant cation affects the rate of conduction as a first step to designing new solid oxide fuel cell materials.

Simulating the surface structure of materials

Understanding how impurtities interact with the surfaces of materials can enable us to investigate problems including, how heavy metal pollutants interact with the major components of soil, how organic molecules can control the growth of minerals to designing new catalytic materials.

In this project we will use a combination of atomistic and ab-initio technques to make an important contribution to this area of science.

Atomistic simulation of dissolution and growth processes

There are many examples in nature minerals with the same composition, grow in completely different ways depending on their chemical surroundings. In this project we will investigate how the presence of various impurities affects stability and use this information to propose potential new growth mechanisms.
