James Suter


Welcome to my homepage!

I am a Postdoctoral Research Assistant in the group of Professor Peter Coveney in the Centre for Computational Science at University College London.

From 2000 to 2004 I did my PhD in the group of Prof. Michiel Sprik at the University of Cambridge, in collaboration with Schlumberger Cambridge Research and Dr Edo Boek. Since 2005 I have been at the Centre for Computation Science at UCL. I am currently supported by the UK Technology Strategy Board on the NIMES project (www.nimes.org.uk)

Research Interests

My research focuses on the structure and dynamics of layered nanomaterials.

Layered mineral systems fall within the realm of the emergent area known as nanotechnology, where materials are designed and built at the atomic level, an area of science currently at the forefront of academic, industrial, health and public interest. Layered nanomaterials consist of mineral layers separated by polymeric or organic material.Tailoring the structure on the nanometer scale produces composites with novel material properties, which can be significantly different from bulk properties and have already been applied in numerous commercial applications. Applications include: (i) improving the materials performance of biodegradable polymers; (ii) clay swelling inhibitors for drilling fluids; (iii) novel high clay fraction composite materials.

I study how the behaviour and properties of the composites emerges from the underlying interactions between the atoms comprising the mineral and the organic material. I use different computer simulations techniques, depending on the lengthscale of interest. The majority of my work has used Molecular Dynamics (MD) simulations, which model individual atoms as classical particles. I have also used ab initio molecular dynamics, which also simulates the electronic degrees of freedom. I am currently developing more "coarse grained" approaches,  where atoms are grouped together to form “blobs”, which then interact in a realistic way.

One of the aims of my current work is to combine these levels of simulation into a hierarchal multiscale model.

Within the NIMES project, we are developing new clay swelling inhibitors for use as drilling fluid additives. It is hoped that these improved additives will boost cost effective accessing of reserves, sustain and improve existing production and enhance the environmental requirements for production in the UK continental shelf.
