Dr. Daniel JohnsonScientist | Water Desalination and Reuse
Dr. Johnson's research interests focus on: Characterisation of surfaces using atomic force microscopy (AFM), particularly in the assessment of fouling and biofouling of polymer filtration membranes, understanding of their interaction mechanisms and other surfaces of relevance to water purification processes and in the development of novel membranes with improved fouling and biofouling resistance.

Daniel Johnson joined QEERI in February 2016. Over the past 10 years he has made a significant contribution to the characterisation of process equipment surfaces using atomic force microscopy (AFM), particularly in the assessment of fouling of polymer filtration membranes and other surfaces of relevance to water purification processes and in the development of novel membranes with improved fouling and biofouling resistance. Recent work has been in the fields of organic fouling of membranes developed for MBR treatment of industrial wastewater, mitigating scaling in membrane distillation systems for desalination of sea water; polymeric membranes for removal of toxic heavy metals from wastewater and contaminated groundwater and the development of low-fouling membranes, as well as examination of the fine structure of biological samples including mollusc shell morphology and human skin. Previously he worked as a research officer in the Centre for Water Advanced Technology and Environmental Research at Swansea University and as a research fellow at the University of Nottingham, both in the UK.
