About College
- I used to be a junior member of St Anne's College, but now I'm a senior member.
- I have no responsibility whatsoever within St. Anne's College MCR .
- I used to be the Advisor to Associated Colleges at St. Anne's, looking
afer Americans from both the WISC and Boston programmes, and Japanese
students from Rewley House. Now Fat Jim has that job.
- I am the recent graduate representative and financial secretary of the
St. Anne's Association of Senior Members. We do things like organising the
Gaudy. I organised a careers day, uniting past and present
St. Anne's members, a few years ago. Last year we had the first "young" asm
reunion at Shoeless Joe's in London. I'm also the chairman of the brand new
Oxford Branch of the ASM. My ASM plans for this year are to set up a careers
database to help the current JCR members.
- Every now and again I return to Oxford and prop up the front of the bar.
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 outside university
- I am involved with the Air Training Corps (ATC), and am currently a
Squadron Officer with 367 (South Sheffield) Squadron. I used to be the
Commanding Officer of 2267 (Lechlade) Detached Flight. The unit has recently
been upgraded to Squadron status: it's now 1970 (Lechlade) Squadron. In
the move, I've been demoted...Boo! All ATC units are always on the lookout
for new members: young people between the ages of 13 and 18 who have an
interest in aviation and adventure. I have, in the past, been a member of
150 (City of Oxford), 878 (Highworth) and 2182 (Dorchester) Squadrons. Here's
a picture of me in posh togs.
- Do you really think I have time for anything else?
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!
