Dr Alison Parker is engaged in research and teaching at Cranfield University in water and sanitation in low income countries. She is leading Cranfield University's response to the Bill and Melinda Gates Foundation's challenge to "Reinvent the Toilet", using novel membrane technology to treat human waste on-site. She is also involved in developing and testing technologies to treat faecal sludge from pit latrines and container toilets including anaerobic digestion and pyrolysis. This involves characterising the waste and optimising its reuse. She is working at both ends of the technology development process - helping to develop a novel technology for EPSRC and in testing "off the shelf" systems for WSUP.
