Computational colloids

This project investigates how Civil Engineering may be integrated with the emerging field of Synthetic Biology. Combining these fields has potentially transformative implications for both and may generate a new field of Engineering Design.

Imagine a column of sand saturated with billions of engineered bacteria cells. As a force is applied to the top of the column, bacteria in the sand detect an increase in pressure. The bacteria respond by synthesising a new biological material to bind the grains together and resisting the load. The resulting structure would consist of a material where sand grains are only cemented where the forces through the material require.

We are building a proof of concept to show how we might design a manufacturing process where the material itself acts as manufacturer and designer, modelling and responding to its environment. Such a technology would push well beyond the current state of the art and challenge a new generation of engineering designers to think at multiple scales from molecular to the built environment and to anticipate civil engineering with living organisms.
