Strain Engineer

Posted on: 04 March 2022


Colorifix was founded by two synthetic biologists who were developing biological sensors to monitor heavy metal contamination in drinking water in rural Nepal.

While testing these sensors in Kathmandu,  Jim and Orr began to learn about the enormous impact of the dyeing industry on water and human health; and realised that,  rather than simply monitoring the problem,  they had the tools to solve it. With some creativity and a bit of luck,  Colorifix was founded in 2016.
