I am a researcher at Cranfield University, investigating nitrogen fate, speciation and management in an ISO 30500-aligned reinvented non-sewered sanitation system. I hold an MSc in Water Resources Development from BUET. Before joining Cranfield, I worked with the World Bank as an Industrial Water Consultant, focusing on industrial water reuse and recycling. Previously, I worked as a Research Coordinator on the REACH programme, a collaborative water-security research programme between BUET and the University of Oxford, and also gained experience working with UNICEF Bangladesh.
