About
Jay Bullen studied chemistry at UCL (MSci) before completing a PhD at Imperial College focused on water quality and the detection and removal of contaminants, including a research placement in Mexico where he created a low-cost, open-source Arduino method for electrochemical arsenic detection that the NGO Caminos de Agua now uses. He was also seconded to the civil service during his doctorate, leading a project on real-time water quality monitoring that grew out of early interest in wastewater surveillance.
