About College

Sheffield University

I'm now a postdoctoral research associate at the University of Sheffield. I'm working on spatio-temporal patterning in vascular tumour growth. More about that on this website .

About my work

BREWARD IS NOW A DOCTOR. Yes it's official. There's nothing anyone can do about it!!
My D.Phil. (not a scummy PhD) involved studying the mathematics of foam. This was based on fluid dynamics, thin film theory and surfactants. It was about washing up liquids and beer, effectively. Since my webpage is on the mathematics network, here's a bit in detail.

Liquid foams occur in a wide variety of contexts. Practically, they are important, for example, in dampening explosions, collecting radioactive dust, dyeing materials and crop spreading. Foams may also be unwanted: in distillation colums for example. Foams are gas-liquid mixtures where the volume fraction of the liquid phase is small. They are stabilised by one of two effects. Firstly, the presence of surface active agents (surfactants such as washing up liquid) can create small changes in surface tension which greatly increases a foams lifetime. Secondly, if there is a second (volatile) liquid component in the system, evaporation causes changes in concentration of this component which consequently effects the surface tension. My work so far has been in modelling the flow of liquid between two bubbles in a foam.

Anyway, enough of that, here I am doing some practical research in my local pub 'The Horse and Jockey'.

I've got a few publications under my belt, well an M.Sc. thesis on The Spreading of Solder, a D Phil thesis on foams. I've also written a couple of papers with my DPhil supervisors PD Howell, RC Darton, and JR Ockendon. Yes, I did have three supervisors. I used to have another one (T.G Myers ), but he went to Cranfield and then Argentina in an attempt to distance himself from me. I've also written a tumour paper with Helen Byrne and Claire Lewis.

I used to share an office with a few clever people. These were James Oliver, who is never actually there because he's busy following in my footsteps, John Coats, who is in when he isn't pulling Louisa, Mark Shepherd, Keith Gillow and David Epstein . Fat Jim and Tall John are still there: Shepherd and Epstein earn a million pounds an hour in the private sector, while Gillow now gets paid to be a computer agony aunt.

In the future, apparently I invent a time machine. I know this because I came and visited myself several years ago. So here's a picture of me aged 22, 73 and 49.

This is what I look like now. When I grow up, I want to change my hairstyle!
