Self Assembly

From cells building a human embryo to robots using swarm intelligence to work together, the amazing world of self assembly. With Jamie Davies, Sharon Glotzer and Roderich Gross.

Cells working together to build a human embryo, a swarm of bees, robots joining forces to explore challenging terrain. These are all examples of self assembly – the coming together of simple units to form something of great complexity. To explore this wide-ranging area of research Bridget Kendall is joined by experimental biologist Jamie Davies, chemical engineer and physicist Sharon Glotzer and robotics engineer Roderich Gross.

Jamie Davies

Jamie Davies is Professor of Experimental  Anatomy at the University of Edinburgh.  He unravels the processes by which a fertilised human egg is able to develop into an embryo without any external input.  He also talks about using cellular self assembly to grow kidneys in the laboratory.


Roderich Gross

Roderich Gross

Roderich Gross  is Senior Lecturer in Robotics and Computational Intelligence at the University of Sheffield.  He uses small, simple robots – ‘swarmbots’ – to work together without an overall blueprint to carry out a variety of tasks.  Their behaviour is modelled on the swarm intelligence which can be observed in the natural world – flocks of birds, swarms of bees, shoals of fish etc.

Sharon Glotzer is Professor of Chemical Engineering at University of Michigan College of Engineering.  Her work with nanoparticles and molecules uses self assembly to create new materials with properties such as the ability to change shape or colour.  She also envisages using the technology to store data not on hard drives, but in clusters of particles suspended in liquid.

60 Second Idea to Change the World

Jamie Davies feels that the car horn is a blight on urban living.  He proposes a way of using the principles of local control and feedback (both central to cellular self assembly) to reward drivers who refrain from honking their horns when waiting at stop lights.  Jamie proposes that the lights should be fitted with directional microphones which help to dictate the traffic flow, so that a noisy queue of honking  cars will have to wait longer for a green light than a quiet one.
