Peter Barham

My main research work concerns very long molecules (polymers). My main area of interest is how these molecules rearrange themselves when a molten polymer is solidified. In the liquid state the molecules are quite random (rather like many balls of wool after a lot of kittens has played with them); but on solidification the molecules become highly ordered and form beautiful crystals.

I am also interested in the production and processing of environmentally friendly plastics. In particular a range of biodegradable plastics (poly hydroxy alkoantes) that are produced by bacteria and whose use is completely carbon neutral.

The picture shows crystals of polyethylene seen in an electron microscope.

I really do have a life outside Polymer Physics! I am particularly interested in food and penguins and the public understanding of science.

Penguin Research

I have been able to combine my passion for penguins with some of my expertise as a Polymer scientist, by helping to design and now, to test, novel plastic flipper bands. This work is being carried out in conjuntion with the Avian Demogrpahy Unit at the University of Cape Town and with Earthwatch Institute.

Recently, together with colleagues in the Computer Science Department, I have developed a system for the automatic recognition of pengiuns

Food and the Public Engagement with Science

I am very interested in promoting the public engagement with science and combine most of my interests through public and schools lecture demonstrations, most of which involve some aspect of the science of food and cooking.

I have been very much involved in the development of what has become known as "Molecular Gastromony". In particular, my collaborations with Heston Blumenthal, the chef/owner of the Fat Duck have proved most fruitful.
