Professor Nicholas Ashbolt is Dean of the School of Environment, Science and Engineering at Southern Cross University. He has more than 30 years’ experience in environmental microbiology, focusing on coastal pollution issues. His earlier wastewater research with the Australian sugar industry led to subsequent positions with ANSTO (Postdoc, acid mine drainage), Sydney Water Corp (Principal Microbiologist, impact of ocean outfall and riverine discharges) and the United States Environmental Protection Agency (Senior Research Microbiologist, urban water impacts) and establishment of national and international water quality targets through his pioneering quantitative microbial risk assessment research. Examples of his risk-based water quality targets are seen in guidelines for drinking and recreational waters (Health Canada, NHMRC, WHO, U.S. EPA), water reuse guidelines (Natural Resource Management Ministerial Council, WHO, Alberta Health) and ISO/ANSI water standards. His current novel research focuses on the fate and dispersion of enteric viruses and saprozoic pathogens in free-living amoebae in waters, and systems-based urban water approaches to aid in the remediation of coastal water systems.
